WEBVTT - Ep 202 Cancer Part 1: What is it?

0:00:00.080 --> 0:00:03.720
<v Speaker 1>Throughout this series, we'll be discussing many aspects of cancer

0:00:03.760 --> 0:00:07.080
<v Speaker 1>diagnosis and treatment, and we will be sharing several personal

0:00:07.120 --> 0:00:11.119
<v Speaker 1>stories related to cancer. Some listeners might find this content upsetting.

0:00:11.320 --> 0:00:12.640
<v Speaker 1>Please listen with discretion.

0:00:15.000 --> 0:00:17.720
<v Speaker 2>Do you know that you can live without a jugular vein?

0:00:18.600 --> 0:00:21.640
<v Speaker 2>Those were the first words my surgeon told us after

0:00:21.720 --> 0:00:25.400
<v Speaker 2>he removed sed vein during my second excigen surgery for

0:00:25.560 --> 0:00:30.760
<v Speaker 2>sway MISSL carcinoma six months earlier. The newly discovered cancer

0:00:30.920 --> 0:00:34.360
<v Speaker 2>was isolated to my tongue and lymph. Notes the cancer

0:00:34.479 --> 0:00:39.280
<v Speaker 2>was brought on by the human papaloma virus HPV. As

0:00:39.320 --> 0:00:43.159
<v Speaker 2>a gen xer, I probably got it long ago. However,

0:00:43.320 --> 0:00:46.479
<v Speaker 2>my children are likely to be spared HPV and this

0:00:46.640 --> 0:00:50.440
<v Speaker 2>kind of cancer because of the gardess of vaccine. The

0:00:50.520 --> 0:00:53.840
<v Speaker 2>cancer was removed with good margins me and that I've

0:00:53.880 --> 0:00:58.240
<v Speaker 2>probably gotten at all. Then came the radiation to sweep

0:00:58.320 --> 0:01:02.520
<v Speaker 2>up any stray cells hanging around. I received the largest

0:01:02.600 --> 0:01:06.679
<v Speaker 2>dost possible, thirty sessions directed in my neck and mouth.

0:01:07.920 --> 0:01:11.759
<v Speaker 2>Before radiation began, I was told there was a deterioration

0:01:12.000 --> 0:01:16.440
<v Speaker 2>risk to surrounding bone structures. I brushed it off, thinking

0:01:17.040 --> 0:01:21.840
<v Speaker 2>save my life. Nothing else matters. However, the radiation did

0:01:21.840 --> 0:01:25.839
<v Speaker 2>not stop an immediate recurrence. That's when it was drapped

0:01:25.840 --> 0:01:30.119
<v Speaker 2>around my jug of the rain. Then I began chemotherapy.

0:01:30.840 --> 0:01:33.920
<v Speaker 2>This required me to mask after each treatment so as

0:01:33.959 --> 0:01:37.600
<v Speaker 2>not to contaminate the air with chemo. I was only

0:01:37.680 --> 0:01:40.679
<v Speaker 2>a few treatments in when the world shut down due

0:01:40.720 --> 0:01:44.640
<v Speaker 2>to the cod pandemic. Because the public was buying up

0:01:44.680 --> 0:01:48.920
<v Speaker 2>medical protection, supplies on cology ran short and I had

0:01:48.920 --> 0:01:53.800
<v Speaker 2>to source my own masks. Chemo worked where radiation had not.

0:01:54.760 --> 0:01:57.240
<v Speaker 2>I'm in a remission, but cancer is still a part

0:01:57.280 --> 0:02:01.920
<v Speaker 2>of my life. As predicted, the large radiation dose ravage

0:02:02.000 --> 0:02:06.360
<v Speaker 2>the bones of my jaw. It's been seven years since cancer,

0:02:06.400 --> 0:02:10.160
<v Speaker 2>and I still faced an extensive eight hour surgery just

0:02:10.200 --> 0:02:15.320
<v Speaker 2>to refer the damage from treatment itself. The inevitability is

0:02:15.400 --> 0:02:19.000
<v Speaker 2>that without this procedure, it's only a matter of time

0:02:19.040 --> 0:02:23.720
<v Speaker 2>before my jaw simply breaks. There was no saving my teeth.

0:02:24.639 --> 0:02:27.840
<v Speaker 2>Eating without them and with a partial scarred tongue is

0:02:27.880 --> 0:02:32.120
<v Speaker 2>difficult and limited. I needed physical therapy to learn to

0:02:32.200 --> 0:02:37.520
<v Speaker 2>swallow again. Since Stentser's a contraindicated I'll be living with

0:02:37.600 --> 0:02:42.440
<v Speaker 2>the stigma and drawbacks associated with toothlessness. For the rest

0:02:42.480 --> 0:02:45.639
<v Speaker 2>of my life. Still beats being dead.

0:02:46.919 --> 0:02:49.240
<v Speaker 3>My name's Louise Baines and I have stage four triple

0:02:49.280 --> 0:02:52.400
<v Speaker 3>negative breast cancer. I was first diagnosed stage three eight

0:02:52.480 --> 0:02:54.359
<v Speaker 3>years ago at the age of thirty nine. I have

0:02:54.480 --> 0:02:59.160
<v Speaker 3>the standard treatment chemotherapy, surgery, radiotherapy was eventually back to

0:02:59.160 --> 0:03:02.240
<v Speaker 3>some semblance of then in twenty twenty three, I found

0:03:02.240 --> 0:03:04.960
<v Speaker 3>a suspicious lump in my armpit, a new lymph no tumor.

0:03:05.400 --> 0:03:07.560
<v Speaker 3>I had more surgery, more chemo, but at the end

0:03:07.600 --> 0:03:10.560
<v Speaker 3>of that year, sadly, a ct scam found widespread bone

0:03:10.560 --> 0:03:13.280
<v Speaker 3>mets and lymph no tumors in my chest. My world

0:03:13.280 --> 0:03:17.040
<v Speaker 3>fell apart for the third and most ominous time. I

0:03:17.080 --> 0:03:18.840
<v Speaker 3>was told I'd need to be on treatment for whatever

0:03:18.880 --> 0:03:21.239
<v Speaker 3>time I had left, thought to be around two years,

0:03:21.639 --> 0:03:25.440
<v Speaker 3>treatable to a point, but not curable. Seeing palliative chemo

0:03:25.480 --> 0:03:27.880
<v Speaker 3>on my notes was a bit of a shock. Triple

0:03:27.919 --> 0:03:31.120
<v Speaker 3>negative is aggressive and can become resistant to treatment. My

0:03:31.160 --> 0:03:34.639
<v Speaker 3>first line of therapy, chemotherapy and immune therapy got me stable,

0:03:34.840 --> 0:03:37.560
<v Speaker 3>pretty much obliterated all my bone mets, but I had

0:03:37.560 --> 0:03:39.640
<v Speaker 3>progression after a year, so I moved on to a

0:03:39.680 --> 0:03:42.360
<v Speaker 3>new drug. This was a targeted chemotherapy that I had

0:03:42.400 --> 0:03:44.640
<v Speaker 3>only been around for a few years. It gave me

0:03:44.680 --> 0:03:46.640
<v Speaker 3>hope to find some of the ladies on that original

0:03:46.680 --> 0:03:49.880
<v Speaker 3>trial were still stable or no evidence of active disease

0:03:50.080 --> 0:03:52.960
<v Speaker 3>even after five years. I took part in a clinical

0:03:53.000 --> 0:03:55.680
<v Speaker 3>trial with my primary chemo which added an extra trial

0:03:55.760 --> 0:03:58.640
<v Speaker 3>drug into the standard treatment, and I became fascinated with

0:03:58.760 --> 0:04:02.280
<v Speaker 3>the science behind the treatment. Researching the history and development

0:04:02.280 --> 0:04:05.600
<v Speaker 3>of each drug became really interesting to me. That first

0:04:05.640 --> 0:04:08.640
<v Speaker 3>study didn't show any better outcomes than standard treatment, sadly,

0:04:08.840 --> 0:04:10.680
<v Speaker 3>but being part of the research made me feel like

0:04:10.720 --> 0:04:14.000
<v Speaker 3>I was helping in some small way. After my second

0:04:14.040 --> 0:04:16.719
<v Speaker 3>line of treatment started to show resistance after another year,

0:04:17.080 --> 0:04:20.360
<v Speaker 3>I decided to look for another clinical trial. I only

0:04:20.360 --> 0:04:22.640
<v Speaker 3>have a few options left for suitable chemos, and while

0:04:22.640 --> 0:04:24.240
<v Speaker 3>I'm still pretty fit and well, I don't want to

0:04:24.279 --> 0:04:26.840
<v Speaker 3>use them all up too fast. I was approved for

0:04:26.880 --> 0:04:29.320
<v Speaker 3>a trial at the Royal Marsden in the UK, and

0:04:29.360 --> 0:04:32.200
<v Speaker 3>I'm being really well looked after. I'm on my second

0:04:32.200 --> 0:04:35.160
<v Speaker 3>cycle of a targeted immune therapy plus a standard immune

0:04:35.200 --> 0:04:37.479
<v Speaker 3>therapy similar to what I had as my first line.

0:04:37.839 --> 0:04:40.479
<v Speaker 3>It's a phase one expansion trial, so the drug has

0:04:40.480 --> 0:04:42.719
<v Speaker 3>shown someone promising results in one type of cancer and

0:04:42.839 --> 0:04:45.880
<v Speaker 3>is being expanded to include other difficult to treat cancers

0:04:46.160 --> 0:04:49.640
<v Speaker 3>like mine. I'm quietly hopeful. I'm now two years into

0:04:49.640 --> 0:04:51.880
<v Speaker 3>my diagnosis, and I didn't expect to still be here.

0:04:52.279 --> 0:04:54.240
<v Speaker 3>Research is very important to me, and I will be

0:04:54.240 --> 0:04:56.960
<v Speaker 3>forever grateful for the extra time I've been given with

0:04:57.000 --> 0:05:00.080
<v Speaker 3>my son, my husband, and my friends. Statistics haven't quite

0:05:00.120 --> 0:05:02.159
<v Speaker 3>caught up with the current treatment, so I wouldn't recommend

0:05:02.160 --> 0:05:05.120
<v Speaker 3>googling for a prognosis. According to that, I should be

0:05:05.160 --> 0:05:07.720
<v Speaker 3>in the ground long ago. But right now I'm living

0:05:07.760 --> 0:05:10.280
<v Speaker 3>well and hopefully we'll continue to do so for as

0:05:10.320 --> 0:05:11.880
<v Speaker 3>long as I can thanks to science.

0:05:58.240 --> 0:06:01.160
<v Speaker 1>Thank you so so much for sharing your story with us,

0:06:01.200 --> 0:06:04.159
<v Speaker 1>and a huge thank you to everyone who has written

0:06:04.200 --> 0:06:06.880
<v Speaker 1>in with their experiences. It is, I mean, it is

0:06:06.920 --> 0:06:10.679
<v Speaker 1>so incredibly meaningful that so many of you are willing

0:06:10.720 --> 0:06:14.040
<v Speaker 1>to put yourselves out there and share such an intimate

0:06:14.040 --> 0:06:17.600
<v Speaker 1>part of your lives. These first hand accounts are truly,

0:06:17.800 --> 0:06:19.920
<v Speaker 1>truly are the backbone of this podcast.

0:06:20.000 --> 0:06:22.440
<v Speaker 4>They really are, Like this podcast would not be the

0:06:22.480 --> 0:06:25.520
<v Speaker 4>same without all of you and all of your stories.

0:06:25.839 --> 0:06:27.400
<v Speaker 4>And we have a lot more that we're going to

0:06:27.440 --> 0:06:30.640
<v Speaker 4>be sharing throughout this episode and throughout this series that

0:06:30.640 --> 0:06:33.680
<v Speaker 4>we're putting together. So truly, thank you so much to

0:06:33.800 --> 0:06:36.400
<v Speaker 4>everybody who took the time to submit your story, to

0:06:36.440 --> 0:06:39.480
<v Speaker 4>write in to record yourselves. We really wish that we

0:06:39.520 --> 0:06:41.760
<v Speaker 4>could have included every single story because they all mean

0:06:41.839 --> 0:06:43.279
<v Speaker 4>so much to us, So thank you.

0:06:43.520 --> 0:06:46.320
<v Speaker 1>Yeah. Hi, I'm Aaron Welsh.

0:06:46.080 --> 0:06:47.680
<v Speaker 4>And I'm Erin Alman Updike and.

0:06:47.720 --> 0:06:49.600
<v Speaker 1>This is this podcast will kill you.

0:06:49.720 --> 0:06:52.400
<v Speaker 4>Welcome to our series on cancer.

0:06:52.720 --> 0:06:57.840
<v Speaker 1>On cancer. Yeah, well I don't know this, I mean

0:06:58.240 --> 0:07:00.560
<v Speaker 1>such a big topic. I mean, we may the decision

0:07:00.560 --> 0:07:02.919
<v Speaker 1>because it is. It is a checked so many people.

0:07:02.960 --> 0:07:05.479
<v Speaker 1>It is such a big topic and if we ever

0:07:05.480 --> 0:07:08.080
<v Speaker 1>want to go into certain cancer episodes in the future,

0:07:08.200 --> 0:07:09.760
<v Speaker 1>we need to lay a foundation.

0:07:10.080 --> 0:07:13.440
<v Speaker 4>And that's what we're doing. That's to today.

0:07:12.640 --> 0:07:17.320
<v Speaker 1>Right right, We have got four absolutely info packed episodes

0:07:17.360 --> 0:07:19.080
<v Speaker 1>ahead of us where we're going to be covering this

0:07:19.480 --> 0:07:22.000
<v Speaker 1>tremendously huge, monumental.

0:07:21.480 --> 0:07:22.920
<v Speaker 4>Topic and only four episodes.

0:07:23.000 --> 0:07:25.720
<v Speaker 1>In only four episodes, Oh, there's like a lot of

0:07:25.960 --> 0:07:26.640
<v Speaker 1>material here.

0:07:26.680 --> 0:07:29.240
<v Speaker 4>Oh yeah, we'll yeah, you can't see our folders, but

0:07:30.320 --> 0:07:30.680
<v Speaker 4>this is.

0:07:30.680 --> 0:07:34.120
<v Speaker 1>One episode's worth. Yeah. But when we first decided that

0:07:34.160 --> 0:07:37.440
<v Speaker 1>we wanted to do these episodes, we immediately kind of okay,

0:07:37.480 --> 0:07:39.440
<v Speaker 1>we asked ourselves what do we want to cover, how

0:07:39.440 --> 0:07:42.640
<v Speaker 1>do we want to approach this, what aspects to focus on,

0:07:42.920 --> 0:07:44.880
<v Speaker 1>and how to organize them in a way that made

0:07:44.920 --> 0:07:48.480
<v Speaker 1>sense so that we could just like again, lay a foundation.

0:07:48.920 --> 0:07:51.280
<v Speaker 1>So our goal with this series is to do that,

0:07:51.440 --> 0:07:53.680
<v Speaker 1>is to kind of give you the background information about

0:07:54.040 --> 0:07:56.840
<v Speaker 1>what cancer is, how we treat it, and also where

0:07:56.880 --> 0:07:59.160
<v Speaker 1>do we go from here? And so with that in

0:07:59.200 --> 0:08:03.080
<v Speaker 1>mind are our first episode The one today explores what

0:08:03.160 --> 0:08:07.000
<v Speaker 1>cancer is, both conceptually and clinically, and how we came

0:08:07.040 --> 0:08:10.560
<v Speaker 1>by that knowledge. The second delves into what's happening inside

0:08:10.600 --> 0:08:13.080
<v Speaker 1>and outside of our bodies to make cancer so prevalent,

0:08:13.640 --> 0:08:16.720
<v Speaker 1>and the third is all about treatment, which.

0:08:16.520 --> 0:08:18.840
<v Speaker 4>Is a lot big it's a big top.

0:08:20.120 --> 0:08:23.560
<v Speaker 1>And the fourth and final episode surveys the current landscape

0:08:23.600 --> 0:08:26.320
<v Speaker 1>of cancer around the world and asks what can we

0:08:26.360 --> 0:08:26.920
<v Speaker 1>do about this?

0:08:27.040 --> 0:08:29.640
<v Speaker 4>Where do we go from here? So it's a lot

0:08:29.720 --> 0:08:31.760
<v Speaker 4>there's a lot of ground that we're going to be covering,

0:08:31.880 --> 0:08:33.920
<v Speaker 4>but as much as we are covering, there is a

0:08:33.960 --> 0:08:38.800
<v Speaker 4>lot that will necessarily remain unexplored in this first of

0:08:38.800 --> 0:08:42.719
<v Speaker 4>our cancer series. So please everyone listening and watching, No.

0:08:42.840 --> 0:08:47.080
<v Speaker 4>Two things Number One, we have a really huge list

0:08:47.080 --> 0:08:50.040
<v Speaker 4>of sources for these episodes that we put together, so

0:08:50.080 --> 0:08:52.120
<v Speaker 4>if you want to read more, there is tons that

0:08:52.160 --> 0:08:55.240
<v Speaker 4>you can look up and read just as a starting point.

0:08:56.360 --> 0:08:58.920
<v Speaker 4>And number two, these are not the only cancer episodes

0:08:58.960 --> 0:09:02.120
<v Speaker 4>that we've ever done that we ever will do. We

0:09:02.280 --> 0:09:04.200
<v Speaker 4>have a lot of plans to cover a lot of

0:09:04.200 --> 0:09:06.600
<v Speaker 4>the individual cancers that we'll be talking about and touching

0:09:06.600 --> 0:09:09.160
<v Speaker 4>on in this episode. So we also would love to

0:09:09.160 --> 0:09:12.120
<v Speaker 4>hear from you if you have particular cancers or particular

0:09:12.120 --> 0:09:13.560
<v Speaker 4>topics that you want to hear a lot more about.

0:09:13.640 --> 0:09:15.920
<v Speaker 4>I know, just like we know that we'll need to

0:09:15.920 --> 0:09:17.360
<v Speaker 4>do callon Cancer very soon.

0:09:17.480 --> 0:09:20.360
<v Speaker 1>Yeah, and we will be doing it. Let's tell your thoughts.

0:09:20.360 --> 0:09:24.439
<v Speaker 1>Like again, we always ask for thoughts, but like especially

0:09:24.440 --> 0:09:26.560
<v Speaker 1>in this what do you want to hear more about

0:09:26.600 --> 0:09:30.000
<v Speaker 1>exactly exactly and as you'll hear you know, know to

0:09:30.280 --> 0:09:33.520
<v Speaker 1>cancers or experiences with cancer are alike. And so we

0:09:33.600 --> 0:09:37.200
<v Speaker 1>are again so grateful to our first hand account providers

0:09:37.200 --> 0:09:40.320
<v Speaker 1>for showing us just a sample really like a sample

0:09:40.440 --> 0:09:43.880
<v Speaker 1>of the diversity of ways that cancer can touch our lives.

0:09:44.400 --> 0:09:47.440
<v Speaker 1>You know, in these episodes, what we focus on is

0:09:47.600 --> 0:09:52.240
<v Speaker 1>primarily cancer as like a biological phenomenon, not necessarily the

0:09:52.280 --> 0:09:56.400
<v Speaker 1>experience of cancer. And so we are again eternally grateful

0:09:56.640 --> 0:09:59.319
<v Speaker 1>to all of you who have provided this important context

0:09:59.360 --> 0:10:02.839
<v Speaker 1>and sharing your experience from of someone who has been

0:10:02.880 --> 0:10:06.400
<v Speaker 1>diagnosed with cancer, who's undergoing cancer treatment, who's has a

0:10:06.559 --> 0:10:09.160
<v Speaker 1>loved one who has cancer, who is a caregiver, you know,

0:10:09.200 --> 0:10:12.400
<v Speaker 1>all all of these different facets that are so integral

0:10:12.440 --> 0:10:13.120
<v Speaker 1>to the experience.

0:10:13.200 --> 0:10:17.080
<v Speaker 4>We really like can't say enough I know how much

0:10:17.160 --> 0:10:19.640
<v Speaker 4>these first hand accounts mean absolutely everything to us, and

0:10:20.000 --> 0:10:22.560
<v Speaker 4>in this cancer series especially, it's been so meaningful to

0:10:22.600 --> 0:10:24.240
<v Speaker 4>get to hear from so many of you, So thank

0:10:24.280 --> 0:10:24.760
<v Speaker 4>you again.

0:10:25.480 --> 0:10:28.439
<v Speaker 1>Okay, one more piece of business, just a little bit,

0:10:28.679 --> 0:10:33.640
<v Speaker 1>and that is quarantine time. Quarantiny time, actually though it's

0:10:33.679 --> 0:10:34.800
<v Speaker 1>play and that's.

0:10:34.679 --> 0:10:38.720
<v Speaker 4>Plassy Berita time. I guess this is an announcement.

0:10:38.200 --> 0:10:41.680
<v Speaker 1>That we're making kind of is we've.

0:10:41.480 --> 0:10:45.600
<v Speaker 4>Been doing this quarantiny business since we started the podcast,

0:10:45.600 --> 0:10:48.280
<v Speaker 4>and it's actually one of the things that really clinched

0:10:48.280 --> 0:10:50.600
<v Speaker 4>the idea of doing this podcast. Would kill you, because

0:10:50.600 --> 0:10:52.480
<v Speaker 4>Aaron came up with the name Quarantini and it was

0:10:52.559 --> 0:10:59.000
<v Speaker 4>too good to pass up. But we thought that as

0:10:59.040 --> 0:11:02.480
<v Speaker 4>we'll learn, so we've talked about alcohol before and the

0:11:02.600 --> 0:11:05.320
<v Speaker 4>problems with alcohol in the past, and so we thought

0:11:05.360 --> 0:11:08.320
<v Speaker 4>that this series today, starting today, would be a fitting

0:11:08.360 --> 0:11:12.280
<v Speaker 4>time to no longer include alcohol in our quarantini recipes.

0:11:12.760 --> 0:11:15.439
<v Speaker 4>So they're technically all going to be plassy burritas.

0:11:15.360 --> 0:11:17.120
<v Speaker 1>They are they are. I mean, we're still going to

0:11:17.280 --> 0:11:19.960
<v Speaker 1>use the term quarantini because it's really good. I can't

0:11:20.000 --> 0:11:21.920
<v Speaker 1>let it go. I can't let it go.

0:11:22.000 --> 0:11:24.680
<v Speaker 4>But I'm also quite proud of plassy burrita. That's really good.

0:11:25.200 --> 0:11:27.680
<v Speaker 1>And I remember when that we came up with that. Yeah,

0:11:27.760 --> 0:11:29.040
<v Speaker 1>it was on the It was on the fly.

0:11:29.240 --> 0:11:31.440
<v Speaker 4>Yeah again, it was I think while we were recording,

0:11:31.520 --> 0:11:33.000
<v Speaker 4>wasn't it. Yes, Yeah, that was good.

0:11:33.160 --> 0:11:35.880
<v Speaker 1>Yeah, yeah, Okay, So what is our quarantining? What is

0:11:35.920 --> 0:11:36.920
<v Speaker 1>it for the series?

0:11:37.080 --> 0:11:37.240
<v Speaker 5>Aron?

0:11:37.360 --> 0:11:42.240
<v Speaker 4>We're drinking the crab, the crab because cancer. Yeah, that's

0:11:42.240 --> 0:11:45.760
<v Speaker 4>what it is. Yeah, it's basically an aphagado. Yes, I

0:11:45.760 --> 0:11:47.680
<v Speaker 4>actually really wish that we had one. That would be

0:11:47.720 --> 0:11:48.079
<v Speaker 4>so much.

0:11:49.040 --> 0:11:51.440
<v Speaker 1>I could use a little caffeine at a little boost.

0:11:51.520 --> 0:11:54.440
<v Speaker 4>Yeah, yeah, but you can. You know, we'll still post

0:11:55.480 --> 0:11:57.560
<v Speaker 4>on our Instagram or whatever.

0:11:59.280 --> 0:12:03.719
<v Speaker 1>Wow, we'll bringing endorsement of our social media listen, still post.

0:12:05.040 --> 0:12:06.880
<v Speaker 4>Our social media game could probably use some work at

0:12:06.880 --> 0:12:08.720
<v Speaker 4>this point, but I know.

0:12:09.960 --> 0:12:12.559
<v Speaker 1>We will post it there and you know it's fine.

0:12:12.920 --> 0:12:15.079
<v Speaker 1>You can look it up the recipe, but also look

0:12:15.200 --> 0:12:18.520

<v Speaker 4>Thanks great.

0:13:11.240 --> 0:13:23.120
<v Speaker 6>Bye.

0:13:27.400 --> 0:13:30.640
<v Speaker 7>My name is Amanda. In twenty nineteen, at fifty two,

0:13:31.040 --> 0:13:34.400
<v Speaker 7>I was diagnosed with stage three triple negative breast cancer.

0:13:34.760 --> 0:13:37.960
<v Speaker 7>The diagnosis was a shock, not only because of its severity,

0:13:38.280 --> 0:13:41.280
<v Speaker 7>but because I truly believed I was doing everything right.

0:13:41.760 --> 0:13:45.200
<v Speaker 7>For years, I followed a clean alternative wellness lifestyle. I

0:13:45.200 --> 0:13:49.559
<v Speaker 7>it organic, avoided plastics, used non toxic products, took supplements,

0:13:49.640 --> 0:13:53.440
<v Speaker 7>exercise regularly, maintained a healthy weight on a low carb diet,

0:13:53.520 --> 0:13:58.359
<v Speaker 7>and didn't smoke. One pivotal decision was replacing annual mammograms

0:13:58.559 --> 0:14:02.720
<v Speaker 7>with thermal imaging. Felt empowering in hindsight, it was a

0:14:02.760 --> 0:14:06.040
<v Speaker 7>serious mistake. When I found a lump in my left breast,

0:14:06.360 --> 0:14:09.960
<v Speaker 7>I turned to thermal imaging. The scan came back low

0:14:10.040 --> 0:14:13.079
<v Speaker 7>risk for cancer. The practitioner diagnosed it as a cyst,

0:14:13.559 --> 0:14:17.760
<v Speaker 7>suggested rebounding exercises and cost oil robes, and confidently told

0:14:17.800 --> 0:14:20.560
<v Speaker 7>me it was far too large to be cancer. That

0:14:20.720 --> 0:14:26.400
<v Speaker 7>reassurance was dangerously wrong. The lump didn't shrink, It grew

0:14:26.480 --> 0:14:30.280
<v Speaker 7>quickly and painfully. When I finally saw a breast radiologist

0:14:30.360 --> 0:14:32.800
<v Speaker 7>to aspirate what I believed was a cyst. My cancer

0:14:32.920 --> 0:14:36.800
<v Speaker 7>journey began. I was thrust into aggressive treatment because my

0:14:36.960 --> 0:14:41.600
<v Speaker 7>cancer demanded it. I underwent six cycles of chemotherapy, including

0:14:41.600 --> 0:14:44.480
<v Speaker 7>the so called Red Devil. I tolerated it well and

0:14:44.520 --> 0:14:49.640
<v Speaker 7>the results were remarkable. The tumor disappeared completely. Surgery followed,

0:14:49.920 --> 0:14:54.600
<v Speaker 7>first to lumpectomy, then a unilateral mistectomy due to residial disease.

0:14:55.240 --> 0:14:59.360
<v Speaker 7>Losing my breast was and remains a profound loss. I

0:14:59.400 --> 0:15:02.680
<v Speaker 7>still wondered whether the earlier medical or intervention might have

0:15:02.800 --> 0:15:07.560
<v Speaker 7>changed that outcome. Radiation and oral chemotherapy followed during South

0:15:07.600 --> 0:15:13.120
<v Speaker 7>Africa's COVID lockdown. The treatments were challenging, but manageable cancer

0:15:13.200 --> 0:15:15.880
<v Speaker 7>forced me to re evaluate everything I thought I knew

0:15:15.920 --> 0:15:19.280
<v Speaker 7>about health. Over time, I stopped trusting methods that offered

0:15:19.320 --> 0:15:23.160
<v Speaker 7>certainty without evidence, and learned to hold space for both

0:15:23.200 --> 0:15:27.080
<v Speaker 7>intuition and science. My version of health today is far

0:15:27.160 --> 0:15:30.960
<v Speaker 7>less rigid, less fear based, and more informed. I have

0:15:31.120 --> 0:15:34.200
<v Speaker 7>seen how vulnerable people are to misinformation, wrapped in hope

0:15:34.480 --> 0:15:37.560
<v Speaker 7>and sold as wellness. And if there's one message I

0:15:37.680 --> 0:15:41.280
<v Speaker 7>hope people take from my story is that there's strength

0:15:41.440 --> 0:15:44.680
<v Speaker 7>in questioning our beliefs and in choosing evidence based care.

0:15:45.960 --> 0:15:48.760
<v Speaker 5>Hi. My name is mccannaugh Elvin ORMMBT, Florida, and when

0:15:48.760 --> 0:15:51.320
<v Speaker 5>I was fifteen years old, I was diagnosed with stage

0:15:51.320 --> 0:15:55.440
<v Speaker 5>three uing circoma aware from my bone cancer. My aud's

0:15:55.440 --> 0:15:58.440
<v Speaker 5>survival were about fifty thirfty. I underwent countless runs a

0:15:58.520 --> 0:16:01.280
<v Speaker 5>chemotherapy and had a serious to remove my left fibula.

0:16:02.080 --> 0:16:04.240
<v Speaker 5>Because of how aggressive the type of cancer I had was,

0:16:04.280 --> 0:16:07.360
<v Speaker 5>cancer immediately became my entire life. I was pulled from

0:16:07.360 --> 0:16:09.280
<v Speaker 5>school and spent most of my time in the hospital.

0:16:09.760 --> 0:16:11.840
<v Speaker 5>It felt like I didn't exist outside of my disease.

0:16:12.560 --> 0:16:14.520
<v Speaker 5>There was also just this chance I wasn't going to

0:16:15.480 --> 0:16:18.360
<v Speaker 5>Chemotherapy is also pretty violent in nature. It felt like

0:16:18.360 --> 0:16:19.800
<v Speaker 5>every part of me had to be stripped away in

0:16:19.920 --> 0:16:22.400
<v Speaker 5>order to get rid of the tumor. I lost my hair,

0:16:22.600 --> 0:16:24.720
<v Speaker 5>my tone as will turn black and fall off. I

0:16:24.760 --> 0:16:27.240
<v Speaker 5>had horrible mouse words that kept me from eating. I

0:16:27.280 --> 0:16:30.480
<v Speaker 5>had chronic insomnia. Felt like I kept giving and giving

0:16:30.600 --> 0:16:32.360
<v Speaker 5>until by the end I was just a shadow of

0:16:32.360 --> 0:16:35.280
<v Speaker 5>a person with really only my life left. I ended

0:16:35.320 --> 0:16:37.160
<v Speaker 5>up responding well to treatment, though, and I was able

0:16:37.200 --> 0:16:38.720
<v Speaker 5>to go back to school for my senior year of

0:16:38.800 --> 0:16:39.240
<v Speaker 5>high school.

0:16:39.280 --> 0:16:41.240
<v Speaker 4>Two years after my initial diagnosis.

0:16:41.840 --> 0:16:43.720
<v Speaker 5>At first, I was excited to go back and built

0:16:43.720 --> 0:16:45.360
<v Speaker 5>it'd be a new chapter for me, we where I'd

0:16:45.400 --> 0:16:47.920
<v Speaker 5>be a normal kid again. Instead, I began a whole

0:16:47.920 --> 0:16:51.040
<v Speaker 5>different type of suffering. Sitting in a desk, I felt

0:16:51.080 --> 0:16:53.000
<v Speaker 5>like I didn't know how to exist as a person anymore.

0:16:53.320 --> 0:16:55.560
<v Speaker 5>I'd gone from being fifteen so coming into my own

0:16:55.600 --> 0:16:58.760
<v Speaker 5>to cancer becoming my entire life. I now couldn't claim

0:16:58.760 --> 0:17:01.480
<v Speaker 5>the cancer identity, but also physically and mentally, I didn't

0:17:01.480 --> 0:17:04.480
<v Speaker 5>resemble the person I was before. Looking in the mirror,

0:17:04.520 --> 0:17:07.199
<v Speaker 5>I followed disassociation to that person and couldn't grasp who

0:17:07.280 --> 0:17:10.400
<v Speaker 5>I was the same time I was suffering from PTSD,

0:17:11.040 --> 0:17:13.520
<v Speaker 5>I was continuously having panic attacks and took myself to

0:17:13.600 --> 0:17:16.520
<v Speaker 5>the emergency room on a couple of different occasions, convinced

0:17:16.560 --> 0:17:18.280
<v Speaker 5>my cancer had returned and I was going not to

0:17:18.280 --> 0:17:21.200
<v Speaker 5>start the process all over again. I ended up becoming

0:17:21.240 --> 0:17:23.360
<v Speaker 5>severely depressed and got to the point where I really

0:17:23.400 --> 0:17:25.680
<v Speaker 5>didn't want to be alive anymore, which brought on a

0:17:25.760 --> 0:17:29.240
<v Speaker 5>deep survivor's guilt for even having these feelings. People weren't

0:17:29.320 --> 0:17:31.879
<v Speaker 5>very understanding of. This ended up being a really isolating

0:17:31.880 --> 0:17:33.760
<v Speaker 5>and lonely time in my life, and I just wish

0:17:33.840 --> 0:17:35.240
<v Speaker 5>someone had told me that what I was feeling was

0:17:35.280 --> 0:17:38.600
<v Speaker 5>completely normal. One in five people ended up with PTSD

0:17:38.640 --> 0:17:41.520
<v Speaker 5>after cancer treatment. It took me years to find a

0:17:41.560 --> 0:17:44.199
<v Speaker 5>sense of self and peace again. This past July was

0:17:44.240 --> 0:17:47.359
<v Speaker 5>my ten years cancer free. I'm eternally grateful for all

0:17:47.440 --> 0:17:49.399
<v Speaker 5>the moments and experiences and things I've been able to

0:17:49.400 --> 0:17:51.760
<v Speaker 5>accomplish since I was at fifteen year old. I am

0:17:51.800 --> 0:17:54.280
<v Speaker 5>truly so happy for my life. But I also want

0:17:54.320 --> 0:17:55.600
<v Speaker 5>to go back to tell myself that what I was

0:17:55.600 --> 0:17:58.199
<v Speaker 5>feeling was okay. I didn't need to feel grateful for

0:17:58.240 --> 0:18:00.000
<v Speaker 5>something that should have never happened in the first place.

0:18:00.680 --> 0:18:26.080
<v Speaker 5>No matter what, I was always deserving of my life.

0:18:30.240 --> 0:18:33.359
<v Speaker 1>Forty percent of us will develop cancer at some point

0:18:33.400 --> 0:18:38.600
<v Speaker 1>in our lives. Seventeen percent of us will die from cancer.

0:18:39.520 --> 0:18:42.200
<v Speaker 4>Gosh, those are such sobering statistics, Aaron.

0:18:42.080 --> 0:18:45.640
<v Speaker 1>Really, yeah, I know the number of times I double

0:18:45.720 --> 0:18:50.000
<v Speaker 1>checked it and was like, confirm other sources. Is this right?

0:18:50.280 --> 0:18:53.760
<v Speaker 1>It is? And again you know these are estimates, they

0:18:53.800 --> 0:18:57.960
<v Speaker 1>are not destinies. Our knowledge is always evolving, treatments are

0:18:58.000 --> 0:19:02.040
<v Speaker 1>always improving, We're putting more fun into prevention and so

0:19:02.119 --> 0:19:05.280
<v Speaker 1>we might see those numbers shift in the upcoming decades

0:19:05.400 --> 0:19:10.160
<v Speaker 1>or for future generations. And neither are these numbers globally consistent.

0:19:10.280 --> 0:19:13.920
<v Speaker 1>You know, diagnosis, access to treatments, and screening, and demographics

0:19:14.000 --> 0:19:19.600
<v Speaker 1>vary dramatically across countries. But no matter how much you

0:19:19.680 --> 0:19:24.720
<v Speaker 1>hedge or qualify these estimates with well technically, the undeniable

0:19:24.920 --> 0:19:29.200
<v Speaker 1>reality is that cancer is extremely common and quite deadly.

0:19:30.240 --> 0:19:36.880
<v Speaker 1>Why Why Why? That one word question has inspired countless

0:19:36.920 --> 0:19:43.719
<v Speaker 1>research articles, medical foundations, textbooks, hospitals, memoirs, documentaries, podcasts. It

0:19:43.760 --> 0:19:50.399
<v Speaker 1>has shaped lives, careers, relationships, perspectives. It holds the key

0:19:50.480 --> 0:19:55.520
<v Speaker 1>to understanding not just this disease, but multicellular life itself.

0:19:56.240 --> 0:19:58.960
<v Speaker 1>Over these four episodes, we might not fully answer this

0:19:59.080 --> 0:20:02.600
<v Speaker 1>question of why why, Yeah, but we are going to

0:20:02.680 --> 0:20:07.920
<v Speaker 1>explore many different aspects, many dimensions of it, like why

0:20:08.000 --> 0:20:11.680
<v Speaker 1>cancer is so prevalent, why it's so challenging to treat

0:20:11.760 --> 0:20:16.360
<v Speaker 1>and prevent, why each cancer is unique, and why despite

0:20:16.480 --> 0:20:20.080
<v Speaker 1>all these whys, we should still be optimistic about the

0:20:20.119 --> 0:20:23.639
<v Speaker 1>future of cancer research. I like that part, yeah, But

0:20:23.760 --> 0:20:26.760
<v Speaker 1>before we approach any of these individual questions, we need

0:20:26.800 --> 0:20:29.840
<v Speaker 1>to start at the beginning. What is cancer?

0:20:30.040 --> 0:20:31.720
<v Speaker 4>What is cancer.

0:20:32.560 --> 0:20:35.520
<v Speaker 1>Drawing the bounds around what cancer is and what it

0:20:35.600 --> 0:20:38.160
<v Speaker 1>isn't is trickier than it sounds like. Just ask our

0:20:38.160 --> 0:20:43.280
<v Speaker 1>immune systems, and those boundaries have changed substantially over history,

0:20:43.640 --> 0:20:46.080
<v Speaker 1>and so for my part of this first episode, I'm

0:20:46.119 --> 0:20:49.040
<v Speaker 1>going to explore how our understanding of cancer has changed

0:20:49.080 --> 0:20:52.679
<v Speaker 1>over time and how that has influenced the noise or

0:20:52.720 --> 0:20:54.119
<v Speaker 1>the silence surrounding it.

0:20:54.200 --> 0:20:55.880
<v Speaker 4>Okay, okay.

0:20:56.040 --> 0:20:58.680
<v Speaker 1>In the early decades of the twentieth century, after the

0:20:58.760 --> 0:21:02.720
<v Speaker 1>dust had settled from that vaccines, pasturization, sanitation and a

0:21:02.720 --> 0:21:06.680
<v Speaker 1>septic technique and antibiotics, much of the world was surprised

0:21:06.720 --> 0:21:11.560
<v Speaker 1>to find that a health revolution had taken place. Infectious disease,

0:21:11.600 --> 0:21:15.320
<v Speaker 1>which had for millennia made an early, gravely expected norm,

0:21:15.920 --> 0:21:19.360
<v Speaker 1>no longer held the power that it once held. Children

0:21:19.720 --> 0:21:23.840
<v Speaker 1>drinking pasteurized milk and vaccinated against smallpox could now more

0:21:23.920 --> 0:21:27.320
<v Speaker 1>reliably expect to live long enough to experience the joys

0:21:27.320 --> 0:21:31.920
<v Speaker 1>and disappointments of adulthood, and adults drinking clean water and

0:21:32.080 --> 0:21:35.520
<v Speaker 1>operated on by a surgeon with a clean blade were

0:21:35.600 --> 0:21:38.359
<v Speaker 1>now more likely to feel the mixed blessing that came

0:21:38.560 --> 0:21:40.720
<v Speaker 1>with the aches and ailments of old age.

0:21:42.080 --> 0:21:45.920
<v Speaker 4>Well this is so interesting already, Aaron like, I just okay,

0:21:46.000 --> 0:21:48.400
<v Speaker 4>keep going, keep going. I just want to know more.

0:21:50.480 --> 0:21:55.719
<v Speaker 1>Is this cliffhanger? Yeah, you're just like, what is something

0:21:56.400 --> 0:21:57.160
<v Speaker 1>on the horizon?

0:21:57.800 --> 0:21:58.399
<v Speaker 4>It's cancer.

0:21:58.480 --> 0:22:02.399
<v Speaker 1>It's cancer. Yeah. As infectious disease stole less of the spotlight,

0:22:02.560 --> 0:22:05.840
<v Speaker 1>other diseases became more visible. We've talked about this phenomenon

0:22:05.880 --> 0:22:10.040
<v Speaker 1>many times on the podcast, and among these diseases is cancer.

0:22:10.960 --> 0:22:14.040
<v Speaker 1>Cancer was not a new disease, of course, but at

0:22:14.040 --> 0:22:16.600
<v Speaker 1>the beginning of the twentieth century, cancer was not even

0:22:16.680 --> 0:22:19.800
<v Speaker 1>in the top five leading causes of death in the

0:22:19.880 --> 0:22:25.920
<v Speaker 1>United States. Really. Yeah, it was eighth on the list. Wow.

0:22:26.920 --> 0:22:29.680
<v Speaker 4>Yeah, sorry, remind me of the year because my brain is.

0:22:30.280 --> 0:22:33.480
<v Speaker 1>Like nineteen hundred okay, yeah, yeah, not even in the

0:22:33.520 --> 0:22:34.960
<v Speaker 1>top not even in the top five. Wow.

0:22:35.040 --> 0:22:35.399
<v Speaker 2>Okay.

0:22:35.640 --> 0:22:39.199
<v Speaker 1>Life expectancy was forty nine years wow, which is a

0:22:39.200 --> 0:22:41.679
<v Speaker 1>flawed metric. It doesn't take into account the effect that

0:22:41.960 --> 0:22:44.920
<v Speaker 1>of infant and childhood mortality would have on those numbers,

0:22:45.200 --> 0:22:49.320
<v Speaker 1>which was primarily from infectious disease. But overall, people were

0:22:49.359 --> 0:22:52.119
<v Speaker 1>not living as long as they do today, and cancer

0:22:52.280 --> 0:22:57.000
<v Speaker 1>was less prevalent, partly because people were dying before developing cancer.

0:22:57.080 --> 0:23:00.160
<v Speaker 1>Cancer happens to be a disease later in life. Life

0:23:00.240 --> 0:23:03.920
<v Speaker 1>most commonly partly because our relative lack of knowledge about

0:23:03.920 --> 0:23:06.960
<v Speaker 1>cancer meant that many people had cancer but never realized it,

0:23:08.119 --> 0:23:11.200
<v Speaker 1>and partly because certain cancer risk factors, such as smoking,

0:23:11.680 --> 0:23:15.560
<v Speaker 1>were lower than in the following decades. Okay, So, for instance,

0:23:15.600 --> 0:23:17.560
<v Speaker 1>at the turn of the century, a case of lung

0:23:17.600 --> 0:23:20.160
<v Speaker 1>cancer was rare enough to point out to med students

0:23:20.200 --> 0:23:22.200
<v Speaker 1>so that they saw it at least once in their careers.

0:23:22.640 --> 0:23:25.119
<v Speaker 4>Really, that's depressing.

0:23:25.359 --> 0:23:29.240
<v Speaker 1>Yeah, over the first half of the twentieth century, all

0:23:29.280 --> 0:23:31.080
<v Speaker 1>that would change. Yeah, all of it.

0:23:31.119 --> 0:23:35.480
<v Speaker 4>That's quite actually particularly disappointing with regards to lung cancer

0:23:36.240 --> 0:23:39.000
<v Speaker 4>because we're people just not smoking. We need to do

0:23:39.040 --> 0:23:40.800
<v Speaker 4>tobacco as like an actual episode Aarin.

0:23:40.960 --> 0:23:44.280
<v Speaker 1>I have that written in here multiple times. Yeah, there

0:23:44.280 --> 0:23:47.280
<v Speaker 1>are some really interesting trends about like smoking, and of

0:23:47.280 --> 0:23:51.280
<v Speaker 1>course it's very different country to country and by age

0:23:51.280 --> 0:23:53.639
<v Speaker 1>group and stuff like that. But yeah, I mean cigarettes

0:23:53.680 --> 0:23:56.280
<v Speaker 1>were really became popular, especially after the World Wars.

0:23:56.400 --> 0:23:58.280
<v Speaker 4>Got it, ok Okay, that makes sense.

0:23:59.440 --> 0:24:03.280
<v Speaker 1>Over the course the twentieth century, life expectancy rose. Cancer

0:24:03.320 --> 0:24:05.600
<v Speaker 1>research began to shed light on the disease, so that

0:24:05.680 --> 0:24:08.800
<v Speaker 1>more cancers were diagnosed and then lumped into this rapidly

0:24:08.960 --> 0:24:13.760
<v Speaker 1>growing umbrella term of cancer. And certain cancers increased in

0:24:13.760 --> 0:24:17.800
<v Speaker 1>incidents as exposure to carcinogens increased, like with lung cancer

0:24:17.880 --> 0:24:21.520
<v Speaker 1>and cigarettes. Even though cancer was not a new disease,

0:24:21.920 --> 0:24:25.520
<v Speaker 1>even though this rise was driven primarily by growing awareness

0:24:25.640 --> 0:24:29.760
<v Speaker 1>and life expectancy, cancer became labeled as a disease of

0:24:29.800 --> 0:24:36.600
<v Speaker 1>the twentieth century. It represented corruption, consumerism and excess, the

0:24:36.720 --> 0:24:42.919
<v Speaker 1>uncontrolled population growth happening within cities, the danger of nonconformity, oh,

0:24:42.960 --> 0:24:44.440
<v Speaker 1>and the threat of invasion.

0:24:45.200 --> 0:24:47.120
<v Speaker 4>Okay, yeah wow.

0:24:47.680 --> 0:24:53.120
<v Speaker 1>While microbiology had demystified many long feared infectious diseases, cancer

0:24:53.280 --> 0:24:56.840
<v Speaker 1>remained one big question mark that scientists could not answer.

0:24:57.600 --> 0:25:01.119
<v Speaker 1>If cancer cells were part of us, why were they harmful?

0:25:02.000 --> 0:25:05.440
<v Speaker 1>Why did cancer strike one person but not another? Why

0:25:05.480 --> 0:25:09.120
<v Speaker 1>does cancer happen at all? Science couldn't yet provide any

0:25:09.119 --> 0:25:11.879
<v Speaker 1>satisfying answers to these questions, and so people did what

0:25:11.920 --> 0:25:16.520
<v Speaker 1>they so often do, They invented their own. Broadly speaking,

0:25:16.680 --> 0:25:21.400
<v Speaker 1>the explanations, or rather blame, really fell into two main categories,

0:25:21.800 --> 0:25:26.359
<v Speaker 1>modern civilization or yourself. Of course, you are to blame.

0:25:26.480 --> 0:25:28.160
<v Speaker 4>It's your fault. It's your fault.

0:25:28.280 --> 0:25:31.480
<v Speaker 1>Yeah. Throughout much of the late eighteen hundreds and into

0:25:31.480 --> 0:25:35.200
<v Speaker 1>the nineteen seventies, really all the way through that whole time,

0:25:35.240 --> 0:25:38.160
<v Speaker 1>that vast amount of time, people diagnosed with cancer were

0:25:38.160 --> 0:25:40.720
<v Speaker 1>told that they had brought it on themselves by bottling

0:25:40.800 --> 0:25:44.199
<v Speaker 1>up their feelings, that it was the result of depression,

0:25:44.680 --> 0:25:49.119
<v Speaker 1>and a quote unquote cancer prone personality type was constructed.

0:25:49.240 --> 0:25:51.399
<v Speaker 4>Is this just Freud who was diagnosing cancer?

0:25:51.600 --> 0:25:54.639
<v Speaker 1>No, oh my god, this was this is before Freud,

0:25:54.720 --> 0:25:57.800
<v Speaker 1>after Freud. I can't blame Freud for this. I know,

0:25:57.920 --> 0:26:00.680
<v Speaker 1>it's too bad. We do like to do that, we do.

0:26:00.840 --> 0:26:02.199
<v Speaker 1>I'm sure he had a hand in it.

0:26:02.280 --> 0:26:03.240
<v Speaker 4>He was a proponent.

0:26:03.720 --> 0:26:07.720
<v Speaker 1>Yeah, yeah, yeah. So in her book Illness as Metaphor,

0:26:07.960 --> 0:26:13.040
<v Speaker 1>Susan Sontag describes this cancer prone personality type quote the forlorn,

0:26:13.320 --> 0:26:17.680
<v Speaker 1>self hating, emotionally inert creature. She had been diagnosed with cancer,

0:26:17.680 --> 0:26:19.560
<v Speaker 1>and so this is what a lot of people would

0:26:19.600 --> 0:26:23.200
<v Speaker 1>That's like how you were talked about, like, oh, well,

0:26:23.560 --> 0:26:29.159
<v Speaker 1>this creature, this creature. Yeah. At that point, So this

0:26:29.240 --> 0:26:31.760
<v Speaker 1>Illness as Metaphor came out in nineteen seventy seven, and

0:26:31.840 --> 0:26:34.760
<v Speaker 1>at that point cancer had been a subject of intense

0:26:34.960 --> 0:26:39.959
<v Speaker 1>scientific scrutiny for decades, and yet this blame language persisted.

0:26:40.840 --> 0:26:43.760
<v Speaker 1>People are afraid of what they don't understand, and our

0:26:43.840 --> 0:26:49.200
<v Speaker 1>understanding of cancer is relatively new, incomplete, and constantly evolving.

0:26:50.359 --> 0:26:54.240
<v Speaker 1>That imperfect knowledge has resulted in blame. It has resulted

0:26:54.280 --> 0:26:57.879
<v Speaker 1>in fear, and it has resulted in silence and euphemisms.

0:26:58.440 --> 0:27:01.920
<v Speaker 1>When Ulysses S. Grant developed throat cancer in eighteen eighty four,

0:27:02.119 --> 0:27:05.439
<v Speaker 1>his doctor acknowledged that cigars they might have been to blame,

0:27:05.640 --> 0:27:09.960
<v Speaker 1>but added that quote depression and distress of mind was

0:27:10.000 --> 0:27:12.760
<v Speaker 1>a more important factor end quote.

0:27:12.640 --> 0:27:17.639
<v Speaker 4>In the development of throat cancer. Okay, yeah.

0:27:18.880 --> 0:27:22.199
<v Speaker 1>Obituaries in the early twentieth century alluded to quote unquote

0:27:22.359 --> 0:27:25.400
<v Speaker 1>lingering illness as the cause of death rather than print

0:27:25.440 --> 0:27:26.200
<v Speaker 1>the word cancer.

0:27:26.600 --> 0:27:29.359
<v Speaker 4>Really, so they don't want to call it cancer.

0:27:29.400 --> 0:27:31.000
<v Speaker 1>They don't want to call it cancer. And then even

0:27:31.040 --> 0:27:34.119
<v Speaker 1>when the taboo on cancer kind of lifted and there

0:27:34.160 --> 0:27:37.119
<v Speaker 1>was an outcry for more research, there were there was

0:27:37.160 --> 0:27:38.840
<v Speaker 1>like an organization that was like, oh, we want to

0:27:38.840 --> 0:27:40.720
<v Speaker 1>meet to talk about breast cancer, and they were like,

0:27:40.760 --> 0:27:41.480
<v Speaker 1>we can't print that.

0:27:44.440 --> 0:27:47.160
<v Speaker 4>Okay, yeah, great, great, great great, yeah cool.

0:27:47.520 --> 0:27:50.439
<v Speaker 1>When cancer was mentioned during that period, it was often

0:27:50.440 --> 0:27:53.760
<v Speaker 1>in like lurid terms, like Senator Matthew Neely used in

0:27:53.840 --> 0:27:58.480
<v Speaker 1>nineteen twenty eight during a speech demanding funds for cancer research. Quote,

0:27:58.880 --> 0:28:02.280
<v Speaker 1>I proposed to speak a monster that is more insatiable

0:28:02.320 --> 0:28:05.720
<v Speaker 1>than the guillotine. It has prayed and still praise upon

0:28:05.800 --> 0:28:08.840
<v Speaker 1>every nation. It has fed and feasted and fattened on

0:28:08.880 --> 0:28:11.920
<v Speaker 1>the flesh and blood and brains and bones of men

0:28:12.080 --> 0:28:16.080
<v Speaker 1>and women and children in every land. The name of

0:28:16.119 --> 0:28:22.160
<v Speaker 1>this loathsome deadly and insatiate monster is cancer. End quote.

0:28:22.640 --> 0:28:27.800
<v Speaker 4>So interesting, Aaron to go back and look at these

0:28:28.480 --> 0:28:32.760
<v Speaker 4>kinds of ways that we describe cancer and like compare

0:28:32.840 --> 0:28:37.040
<v Speaker 4>that to what how we fighting against cancer today?

0:28:37.200 --> 0:28:37.360
<v Speaker 5>Oh?

0:28:37.440 --> 0:28:40.480
<v Speaker 1>Yeah, I mean there are there are entire books written

0:28:40.520 --> 0:28:43.320
<v Speaker 1>about like the language that we use when we talk

0:28:43.360 --> 0:28:47.040
<v Speaker 1>about cancer. And you know, more recently or since since

0:28:47.080 --> 0:28:50.960
<v Speaker 1>the nineteen seventies, I guess the language is much more

0:28:51.040 --> 0:28:53.720
<v Speaker 1>likely to be military code of yes, right, the war

0:28:53.800 --> 0:28:56.480
<v Speaker 1>on cancer and all out of tack, defeating the enemy,

0:28:56.480 --> 0:29:01.720
<v Speaker 1>and aggressive aggressive, aggressive aggressive, And that shift to this

0:29:01.840 --> 0:29:05.520
<v Speaker 1>military language, it has not eradicated victim blaming, which can

0:29:05.560 --> 0:29:08.320
<v Speaker 1>come in more indirect ways. Right, you know, healthy mind,

0:29:08.360 --> 0:29:12.400
<v Speaker 1>healthy body, The implication that cancer will defeat you if

0:29:12.440 --> 0:29:13.760
<v Speaker 1>you don't fight hard enough.

0:29:13.840 --> 0:29:14.080
<v Speaker 8>Yes.

0:29:15.360 --> 0:29:19.600
<v Speaker 1>And also I think there's this tendency that we all have.

0:29:19.760 --> 0:29:21.680
<v Speaker 1>I think it's human of us that when we hear

0:29:22.200 --> 0:29:24.080
<v Speaker 1>that someone has cancer, we want to know what kind

0:29:24.120 --> 0:29:24.960
<v Speaker 1>of cancer is it?

0:29:25.480 --> 0:29:25.640
<v Speaker 5>Oh?

0:29:25.680 --> 0:29:29.680
<v Speaker 1>Were they a smoker? So that we try to find

0:29:29.720 --> 0:29:32.720
<v Speaker 1>ourselves in that well, well we won't be that won't

0:29:32.720 --> 0:29:33.320
<v Speaker 1>happen to us.

0:29:33.320 --> 0:29:35.880
<v Speaker 4>Trying to understand I didn't do this, what was different

0:29:35.920 --> 0:29:38.880
<v Speaker 4>about you? What's different about me? Why does this not.

0:29:38.800 --> 0:29:41.960
<v Speaker 1>A Why do I want to make sense of this diagnosis?

0:29:42.000 --> 0:29:44.760
<v Speaker 1>And I want to I don't want this to happen

0:29:44.800 --> 0:29:47.400
<v Speaker 1>to me. Yeah, And so we try to find that reason.

0:29:47.480 --> 0:29:49.000
<v Speaker 1>We try to find a cause and effect.

0:29:49.080 --> 0:29:49.280
<v Speaker 6>Yeah.

0:29:50.800 --> 0:29:54.440
<v Speaker 1>And today the fear of cancer and the blame is

0:29:54.520 --> 0:29:58.320
<v Speaker 1>as real and as palpable as ever. Surveys looking at

0:29:58.360 --> 0:30:01.520
<v Speaker 1>fear of chronic diseases show that people fear cancer more

0:30:01.560 --> 0:30:05.480
<v Speaker 1>than any other chronic disease, even though heart disease kills

0:30:05.520 --> 0:30:06.520
<v Speaker 1>warm people one killer.

0:30:06.720 --> 0:30:08.960
<v Speaker 4>That's actually really interesting. I did not know that, Aaron.

0:30:10.280 --> 0:30:12.720
<v Speaker 4>That doesn't surprise me at all, No, because it's the

0:30:12.800 --> 0:30:15.600
<v Speaker 4>thing I mean, I know, like when you have if

0:30:15.640 --> 0:30:19.880
<v Speaker 4>you're concerned about it, everyone wants to tiptoe around do

0:30:19.960 --> 0:30:21.960
<v Speaker 4>we even say that we're concerned about cancer? Or do

0:30:22.000 --> 0:30:24.320
<v Speaker 4>we not even say the word cancer yet? Kind of

0:30:24.360 --> 0:30:26.240
<v Speaker 4>thing that still happens in medicine todays.

0:30:28.680 --> 0:30:30.880
<v Speaker 1>Yeah, I mean that's a whole I know, I have

0:30:30.920 --> 0:30:36.320
<v Speaker 1>a lot of I know, I know, but yeah, I mean, why, Like,

0:30:36.560 --> 0:30:40.239
<v Speaker 1>what is it about cancer that elicits such dread? And

0:30:40.280 --> 0:30:43.200
<v Speaker 1>I don't think that it's an unreasonable fear? Yeah, I

0:30:43.200 --> 0:30:45.640
<v Speaker 1>would not say it at all. I'm I have that fear.

0:30:46.320 --> 0:30:49.080
<v Speaker 1>Forty percent of us will develop cancer at some point

0:30:49.080 --> 0:30:52.720
<v Speaker 1>in our lives. But what that looks like or when

0:30:52.720 --> 0:30:56.040
<v Speaker 1>it might happen, we have no idea. It could mean

0:30:56.080 --> 0:30:59.240
<v Speaker 1>a diagnosis in childhood, in middle age, or later in

0:30:59.280 --> 0:31:01.760
<v Speaker 1>our lives, all of the above, all of the above.

0:31:01.880 --> 0:31:04.960
<v Speaker 1>It could mean a simple curative surgery or a marathon

0:31:05.040 --> 0:31:09.240
<v Speaker 1>of expensive and tortuous treatments. It could mean delayed plans,

0:31:09.440 --> 0:31:13.080
<v Speaker 1>canceled plans, or new plans. It could mean becoming a

0:31:13.120 --> 0:31:17.880
<v Speaker 1>caretaker or being taken care of. It could mean hope, despair, clarity,

0:31:18.040 --> 0:31:21.000
<v Speaker 1>a new knowing. It could mean every one of those things,

0:31:21.000 --> 0:31:24.280
<v Speaker 1>some of those things, or none of those things. Cancer

0:31:24.400 --> 0:31:27.760
<v Speaker 1>is unpredictable by nature, which is part of why it

0:31:27.840 --> 0:31:32.320
<v Speaker 1>inspires such fear. It has touched every one of us,

0:31:32.360 --> 0:31:35.920
<v Speaker 1>ourselves directly or through our family, our friends, our neighbors,

0:31:35.920 --> 0:31:40.640
<v Speaker 1>our colleagues. But we can't necessarily look to others' experiences

0:31:40.680 --> 0:31:45.240
<v Speaker 1>to predict how our own story will unfold. We want answers,

0:31:45.680 --> 0:31:50.000
<v Speaker 1>what's my prognosis, will this treatment work, how long do

0:31:50.080 --> 0:31:54.680
<v Speaker 1>I have? What side effects will I experience? What happens next?

0:31:55.520 --> 0:31:58.640
<v Speaker 1>But most answers are best guesses, formed by decades of

0:31:58.720 --> 0:32:02.920
<v Speaker 1>research and always qualified with it's likely that, but we

0:32:02.960 --> 0:32:06.520
<v Speaker 1>can't know for certain. And that doesn't represent a failure

0:32:06.560 --> 0:32:09.000
<v Speaker 1>on the part of the research community, which has produced

0:32:09.040 --> 0:32:11.719
<v Speaker 1>a true wealth of information when it comes to cancer,

0:32:11.880 --> 0:32:14.400
<v Speaker 1>what it is and how to treat it. Will more

0:32:14.440 --> 0:32:17.680
<v Speaker 1>research helped to fill in those knowledge gaps and shorten

0:32:17.680 --> 0:32:21.480
<v Speaker 1>those error bars in some situations. Yes, but the fact

0:32:21.520 --> 0:32:25.480
<v Speaker 1>remains that cancer is so unpredictable because it is so variable.

0:32:26.160 --> 0:32:30.440
<v Speaker 1>Cancer has many causes, many origins, many pathways, many outcomes,

0:32:30.480 --> 0:32:34.240
<v Speaker 1>and each cancer is distinct. And I don't mean that

0:32:34.320 --> 0:32:38.880
<v Speaker 1>breast cancer is just distinct from prostate cancer. Each individual

0:32:38.960 --> 0:32:42.800
<v Speaker 1>case of breast cancer is unique and as we'll discover

0:32:42.840 --> 0:32:44.760
<v Speaker 1>more next week. When we talk about like the cellular

0:32:44.800 --> 0:32:48.520
<v Speaker 1>biology of cancer, oftentimes that uniqueness goes all the way

0:32:48.880 --> 0:32:51.960
<v Speaker 1>down to the cellular level, with tumors made up of

0:32:51.960 --> 0:32:56.000
<v Speaker 1>a diversity of cancer cells. The more we've discovered about cancer,

0:32:56.120 --> 0:32:59.200
<v Speaker 1>the bigger this term gets. So let's go back to

0:32:59.240 --> 0:33:01.640
<v Speaker 1>the beginning and see if we can trace its growth

0:33:01.640 --> 0:33:03.920
<v Speaker 1>over time, just like.

0:33:03.920 --> 0:33:04.640
<v Speaker 4>A cancer cell.

0:33:05.720 --> 0:33:10.040
<v Speaker 1>Sure, cancer might be a defining disease of our time,

0:33:10.120 --> 0:33:13.640
<v Speaker 1>but that doesn't mean it's only of our time. Fossil

0:33:13.680 --> 0:33:16.360
<v Speaker 1>remains of humans and our hominid relatives show us that

0:33:16.400 --> 0:33:20.080
<v Speaker 1>cancer has been a part of us for millennia and beyond.

0:33:19.880 --> 0:33:21.280
<v Speaker 4>Forever and ever forever.

0:33:21.680 --> 0:33:24.400
<v Speaker 1>A million year old jaw bone found in East Africa

0:33:24.440 --> 0:33:27.000
<v Speaker 1>with evidence of lymphoma A million.

0:33:26.840 --> 0:33:29.760
<v Speaker 4>Yeah, wow, Yeah, what kind of jow bone?

0:33:31.360 --> 0:33:36.280
<v Speaker 1>What like a homind job? Sorry? I was like, no,

0:33:36.320 --> 0:33:38.200
<v Speaker 1>I don't think I wrote the species down because I

0:33:38.240 --> 0:33:40.080
<v Speaker 1>think it was like, we're not really sure anyway.

0:33:40.120 --> 0:33:41.880
<v Speaker 4>Wow, fascinating but yes, okay.

0:33:42.480 --> 0:33:44.880
<v Speaker 1>A growth in a Neanderthal skeleton from one hundred and

0:33:44.880 --> 0:33:48.160
<v Speaker 1>twenty thousand years ago. An ancient Egyptian mummy from four

0:33:48.240 --> 0:33:51.400
<v Speaker 1>hundred CE with abdominal cancer and that's just to name

0:33:51.400 --> 0:33:53.400
<v Speaker 1>a few. I literally cut out so many more examples

0:33:53.400 --> 0:33:56.200
<v Speaker 1>where I was like, there are papers, find them in

0:33:56.240 --> 0:33:56.760
<v Speaker 1>our show.

0:33:56.800 --> 0:33:57.480
<v Speaker 4>Lots of examples.

0:33:57.560 --> 0:34:02.840
<v Speaker 1>Yeah, but looking beyond present absence to prevalence, cancer does

0:34:02.920 --> 0:34:06.160
<v Speaker 1>seem more common today than in centuries or millennia past.

0:34:06.200 --> 0:34:07.920
<v Speaker 1>And that's due to the mix of factors that I

0:34:08.000 --> 0:34:11.480
<v Speaker 1>already mentioned. But it's kind of hard to be more

0:34:11.520 --> 0:34:15.120
<v Speaker 1>specific than that, like how much more prevalent considering that

0:34:15.160 --> 0:34:17.920
<v Speaker 1>cancer doesn't always leave its mark on bone, and that

0:34:17.920 --> 0:34:20.560
<v Speaker 1>we've you know, we've examined only a tiny fraction of

0:34:20.600 --> 0:34:25.320
<v Speaker 1>the fossils or remains that have been left behind. Yeah, okay,

0:34:25.320 --> 0:34:28.360
<v Speaker 1>so what about the written record? Oh so, starting in

0:34:28.440 --> 0:34:32.520
<v Speaker 1>ancient Egypt, naturally, we've got the Edwin Smith papyrus from

0:34:32.560 --> 0:34:35.880
<v Speaker 1>about thirty six hundred years ago, which describes what sounds

0:34:35.920 --> 0:34:38.680
<v Speaker 1>like a case of breast cancer. This is paraphrasing a

0:34:38.680 --> 0:34:42.240
<v Speaker 1>little bit quote. If you put your hand upon his breast,

0:34:42.400 --> 0:34:45.200
<v Speaker 1>upon those tumors, and you find them very cool, there

0:34:45.239 --> 0:34:48.359
<v Speaker 1>being no fever at all. They have no granulation, they

0:34:48.400 --> 0:34:51.480
<v Speaker 1>form no fluid, they do not generate secretions of fluid,

0:34:51.520 --> 0:34:53.040
<v Speaker 1>and they are bulging to your hand.

0:34:53.800 --> 0:34:56.960
<v Speaker 4>End quote, Okay, yeah, could be, could be, could be,

0:34:57.040 --> 0:34:57.360
<v Speaker 4>could be.

0:34:57.600 --> 0:35:02.359
<v Speaker 1>Yeah. And although this papyrus contains many remedies for all

0:35:02.360 --> 0:35:05.439
<v Speaker 1>the other ailments that it has listed in there, there

0:35:05.520 --> 0:35:10.680
<v Speaker 1>is no treatment for this disease. Interesting basically says there's nothing. Yeah.

0:35:10.719 --> 0:35:13.200
<v Speaker 1>So following this, there was a relatively long period of

0:35:13.239 --> 0:35:16.080
<v Speaker 1>silence when it comes to writings about cancer, until we

0:35:16.120 --> 0:35:19.680
<v Speaker 1>get to ancient Greece, where cancer again makes an appearance.

0:35:19.840 --> 0:35:22.359
<v Speaker 1>Not in a medical context this time though, but a

0:35:22.400 --> 0:35:27.000
<v Speaker 1>storytelling one. So the Greek historian Herodotus, writing around four

0:35:27.040 --> 0:35:31.320
<v Speaker 1>hundred and forty BCE, briefly tells the story of Atosa,

0:35:31.440 --> 0:35:34.040
<v Speaker 1>the queen of Persia, who developed a swelling on her

0:35:34.040 --> 0:35:38.160
<v Speaker 1>breast and ultimately headed excised. Was it cancer? Was it

0:35:38.200 --> 0:35:40.680
<v Speaker 1>an ulcer or fiber adnoma?

0:35:40.960 --> 0:35:42.520
<v Speaker 4>Yeah, lots of benign tumors.

0:35:42.640 --> 0:35:45.120
<v Speaker 1>We don't know, We don't know. And it's in the

0:35:45.239 --> 0:35:48.000
<v Speaker 1>Hippocratic texts written in Greece in the fourth and fifth

0:35:48.000 --> 0:35:51.200
<v Speaker 1>centuries BCE, which I still have to look up every time,

0:35:51.680 --> 0:35:53.680
<v Speaker 1>Like if I were to go to trivia and that

0:35:53.840 --> 0:35:57.200
<v Speaker 1>was one of the questions, I would not know. But

0:35:57.320 --> 0:35:59.959
<v Speaker 1>this in the Hippocratic text is when we first find

0:36:00.080 --> 0:36:03.000
<v Speaker 1>the words for cancer and carcinoma or their origins.

0:36:03.040 --> 0:36:05.800
<v Speaker 4>Okay, that's that was gonna be one of my big questions. Yeah,

0:36:05.840 --> 0:36:07.560
<v Speaker 4>so that's a long time ago, time ago.

0:36:07.640 --> 0:36:10.239
<v Speaker 1>So carkinos, carcinos, and carcinoma.

0:36:10.360 --> 0:36:11.200
<v Speaker 4>Okay with ks.

0:36:12.280 --> 0:36:15.520
<v Speaker 1>Carcunose was used to refer to any non healing, swelling

0:36:15.640 --> 0:36:20.279
<v Speaker 1>or ulcerous formation, including things like hemorrhoids or cysts. Okay, interesting,

0:36:20.600 --> 0:36:24.080
<v Speaker 1>while carcunoma was generally reserved for a non healing growth.

0:36:24.239 --> 0:36:28.440
<v Speaker 4>Okay, yeah, non healing growth. This is so interesting.

0:36:28.520 --> 0:36:33.399
<v Speaker 1>M Both words come from the ancient Greek for crab. Ah,

0:36:33.400 --> 0:36:36.320
<v Speaker 1>this is where crab comes from. Okay, So apparently the

0:36:36.360 --> 0:36:39.600
<v Speaker 1>appearance of a tumor surrounded by blood vessels branching out

0:36:40.040 --> 0:36:43.319
<v Speaker 1>reminded Hippocrates and then later Galen of a crab in

0:36:43.480 --> 0:36:45.200
<v Speaker 1>sand with its legs all spread out.

0:36:45.320 --> 0:36:47.440
<v Speaker 4>Interesting. Yeah, so that's how they Okay.

0:36:47.880 --> 0:36:53.200
<v Speaker 1>Yeah. Hippocrates also used the word methistemi for metastasis.

0:36:53.239 --> 0:36:53.399
<v Speaker 6>Oh.

0:36:53.480 --> 0:36:53.960
<v Speaker 4>Interesting.

0:36:54.160 --> 0:36:58.080
<v Speaker 1>Methisdemi means to remove or set free, and he thought

0:36:58.160 --> 0:37:01.759
<v Speaker 1>that quote metastatic affectation are those which travel from one

0:37:02.120 --> 0:37:03.360
<v Speaker 1>to another part of the body.

0:37:03.680 --> 0:37:04.480
<v Speaker 4>Yeah, end quote.

0:37:04.480 --> 0:37:06.960
<v Speaker 1>It's not wrong, Yes, I mean he's not wrong. I

0:37:07.000 --> 0:37:09.560
<v Speaker 1>don't think that, like, I mean, given sort of the

0:37:09.640 --> 0:37:14.800
<v Speaker 1>leading ideas about disease, right, his word, the hit metastasist

0:37:14.840 --> 0:37:17.440
<v Speaker 1>to him is not the same metastasist to us. But

0:37:17.480 --> 0:37:19.960
<v Speaker 1>it is interesting, yeah, the roots of that.

0:37:20.120 --> 0:37:20.319
<v Speaker 4>Yeah.

0:37:20.400 --> 0:37:24.440
<v Speaker 1>Yeah. So then after Hippocrates we run into Galen, whose

0:37:24.520 --> 0:37:28.239
<v Speaker 1>humoral explanation of cancer dominated Western medicine for centuries, a

0:37:28.280 --> 0:37:32.160
<v Speaker 1>build up of black bile, also known as melancholy.

0:37:32.960 --> 0:37:37.040
<v Speaker 4>Oh that's interesting. Yeah, that that's just persistent without people

0:37:37.080 --> 0:37:39.839
<v Speaker 4>probably realizing they were doing that. But so sorry, so

0:37:39.920 --> 0:37:42.239
<v Speaker 4>they were like, cancer is black bile. That's the that's

0:37:42.280 --> 0:37:46.239
<v Speaker 4>the that's there. Yeah, done, done, okay, Yeah. God must

0:37:46.280 --> 0:37:48.360
<v Speaker 4>be nice just to have an explanation for something, huh.

0:37:48.400 --> 0:37:48.960
<v Speaker 1>I mean.

0:37:51.920 --> 0:37:52.640
<v Speaker 4>We wouldn't know.

0:37:52.800 --> 0:37:58.960
<v Speaker 1>No, yeah, we can't all yeah, yeah, yeah we are.

0:37:59.080 --> 0:38:01.200
<v Speaker 1>That's that's that's how we do it on this podcast.

0:38:01.200 --> 0:38:04.560
<v Speaker 1>Will kill you. But so yeah, according to Galen, I mean,

0:38:04.680 --> 0:38:07.320
<v Speaker 1>what you can what you can do with black bile

0:38:07.520 --> 0:38:10.719
<v Speaker 1>is you can maybe like drain a little bit of it,

0:38:10.760 --> 0:38:13.759
<v Speaker 1>but it's really difficult to do. Also black so black

0:38:13.760 --> 0:38:17.640
<v Speaker 1>bile is melancholy, and it's like depression and repeat.

0:38:17.680 --> 0:38:20.800
<v Speaker 4>I don't know about this in your which episode was

0:38:20.840 --> 0:38:23.520
<v Speaker 4>that that you did all of the humors ball bladder?

0:38:23.880 --> 0:38:25.720
<v Speaker 4>And we were like, what is black bile?

0:38:26.760 --> 0:38:28.680
<v Speaker 1>No, so, I mean I didn't put this in here,

0:38:28.719 --> 0:38:31.799
<v Speaker 1>but like this is like and black bile not just

0:38:31.800 --> 0:38:34.480
<v Speaker 1>specific any of the humors, right, people knew what blood,

0:38:34.520 --> 0:38:37.880
<v Speaker 1>people knew whatever, slam, but black bile was this mysterious

0:38:37.920 --> 0:38:39.480
<v Speaker 1>thing that no one could find. And then I think

0:38:39.480 --> 0:38:43.560
<v Speaker 1>it was like visalias. I hope that's right, was trying

0:38:43.600 --> 0:38:47.440
<v Speaker 1>to find he was trying to like confirm Galen's black

0:38:47.480 --> 0:38:50.080
<v Speaker 1>bile and the humoral theory and was like doing auto

0:38:51.320 --> 0:38:54.080
<v Speaker 1>and he was like, I don't find anything where it is.

0:38:54.320 --> 0:38:54.799
<v Speaker 2>What is this?

0:38:55.480 --> 0:38:56.880
<v Speaker 1>And so it was kind of like the beginning of

0:38:56.920 --> 0:38:59.200
<v Speaker 1>the end which had already been under question. Blah blah

0:38:59.200 --> 0:39:02.920
<v Speaker 1>blah blah. Medicine was not stagnant for that long, et cetera.

0:39:03.440 --> 0:39:07.400
<v Speaker 1>So but Galen for the most part was like, I

0:39:07.440 --> 0:39:10.080
<v Speaker 1>don't think that we should treat this. I don't think

0:39:10.080 --> 0:39:11.719
<v Speaker 1>that surgery is the way to go. It's only going

0:39:11.800 --> 0:39:13.799
<v Speaker 1>to speed up progression. And so unless it was like

0:39:13.920 --> 0:39:16.920
<v Speaker 1>very small, he tended to opt to just do nothing, okay,

0:39:18.000 --> 0:39:20.880
<v Speaker 1>And later physicians kind of did the same thing. It

0:39:20.920 --> 0:39:23.680
<v Speaker 1>was very much like some did surgery, some didn't, and

0:39:23.760 --> 0:39:27.520
<v Speaker 1>many other many other, many other surgeons physicians contributed to

0:39:27.560 --> 0:39:30.560
<v Speaker 1>this body of knowledge about cancer, but like it was

0:39:30.719 --> 0:39:34.400
<v Speaker 1>incremental and none of it really moved the needle, yeah,

0:39:34.480 --> 0:39:38.160
<v Speaker 1>in terms of like what does this do for the patient? Right,

0:39:38.719 --> 0:39:41.640
<v Speaker 1>or even like our understanding to then try to develop something.

0:39:43.120 --> 0:39:47.520
<v Speaker 1>And so even though so Galen's black bile concept of

0:39:47.520 --> 0:39:50.840
<v Speaker 1>cancer came uter scrutiny as early as the fourteenth century,

0:39:50.960 --> 0:39:54.360
<v Speaker 1>it overstayd It's welcome, though for much much longer than that,

0:39:55.040 --> 0:39:58.560
<v Speaker 1>no central hypothesis of cancer took its place, and physicians

0:39:58.600 --> 0:40:02.480
<v Speaker 1>remained largely helpless to treat or even just understand this

0:40:02.680 --> 0:40:07.000
<v Speaker 1>disease of many faces. That's so interesting, And things started

0:40:07.000 --> 0:40:10.440
<v Speaker 1>to change around the eighteenth and nineteenth centuries. Okay, all right,

0:40:10.800 --> 0:40:13.120
<v Speaker 1>So science and medicine during this period is marked by

0:40:13.120 --> 0:40:17.360
<v Speaker 1>the invention of tools and techniques that allowed physicians and

0:40:17.400 --> 0:40:21.879
<v Speaker 1>scientists to observe for themselves what had previously been invisible.

0:40:22.719 --> 0:40:27.280
<v Speaker 1>The thermometer that indicated a fever, the stethoscope that detected

0:40:27.280 --> 0:40:30.759
<v Speaker 1>a heart murmur, the microscope that revealed the cells that

0:40:30.920 --> 0:40:35.120
<v Speaker 1>formed us and all of life, the taboo against autopsies

0:40:35.160 --> 0:40:37.799
<v Speaker 1>had been declining for a couple of centuries, which allowed

0:40:37.840 --> 0:40:40.720
<v Speaker 1>people to map out not only how the body worked,

0:40:40.800 --> 0:40:45.200
<v Speaker 1>but also like when things went awry. With this new toolkit,

0:40:45.360 --> 0:40:49.120
<v Speaker 1>patients were more likely to find confirmation and explanation of

0:40:49.160 --> 0:40:53.439
<v Speaker 1>their vague symptoms. Surgery back on the rise, especially once

0:40:53.480 --> 0:40:56.960
<v Speaker 1>antiseptic technique and anesthesia were introduced in the later half

0:40:57.040 --> 0:41:01.080
<v Speaker 1>of the nineteenth century. Surgery revealed that the exhaustion and

0:41:01.160 --> 0:41:03.640
<v Speaker 1>the aches that you had been feeling were likely tied

0:41:03.680 --> 0:41:06.239
<v Speaker 1>to the tumor in your breast that had spread to

0:41:06.320 --> 0:41:09.319
<v Speaker 1>your bone. A slide of your blood cells viewed under

0:41:09.320 --> 0:41:12.840
<v Speaker 1>the microscope pointed towards a proliferation of white blood cells

0:41:12.920 --> 0:41:16.080
<v Speaker 1>as a contributor to the listlessness and abdominal pain you

0:41:16.120 --> 0:41:20.080
<v Speaker 1>had been experiencing. As a medical topic, cancer was not

0:41:20.239 --> 0:41:24.319
<v Speaker 1>unknown to the physicians of this era, but it evaded explanation.

0:41:25.280 --> 0:41:30.279
<v Speaker 1>These new tools surgery, microscope, anatomy, chemistry gave them the

0:41:30.320 --> 0:41:34.759
<v Speaker 1>opportunity to pin down this disease, focusing on two main questions,

0:41:35.239 --> 0:41:37.520
<v Speaker 1>what is cancer and why does it happen?

0:41:38.280 --> 0:41:40.520
<v Speaker 4>This is so interesting erin because I don't think that

0:41:40.640 --> 0:41:44.560
<v Speaker 4>I expected for there to be a kind of unified

0:41:44.760 --> 0:41:50.000
<v Speaker 4>idea that cancer is cancer from that far back, like

0:41:50.080 --> 0:41:51.560
<v Speaker 4>I thought that this was going to be you being

0:41:51.600 --> 0:41:54.000
<v Speaker 4>like and then they thought that this was some weird

0:41:54.040 --> 0:41:55.960
<v Speaker 4>disease and it turned out that was also cancer.

0:41:56.200 --> 0:41:58.399
<v Speaker 1>Like, yes, that is kind of what it. I mean,

0:41:58.640 --> 0:41:59.839
<v Speaker 1>this is things are still coal.

0:42:00.440 --> 0:42:00.840
<v Speaker 4>Yeah.

0:42:00.880 --> 0:42:03.520
<v Speaker 1>So it's just like now we have in the starting

0:42:03.520 --> 0:42:05.600
<v Speaker 1>in the nineteenth century, we have these tools, we have

0:42:05.760 --> 0:42:08.160
<v Speaker 1>this idea of like, Okay, now we're going to throw

0:42:08.200 --> 0:42:10.719
<v Speaker 1>out this black bile theory which had been around for

0:42:10.760 --> 0:42:13.440
<v Speaker 1>a really long time and kind of lingers still, and

0:42:13.480 --> 0:42:15.759
<v Speaker 1>we're going to kind of see like what this individual

0:42:15.800 --> 0:42:18.799
<v Speaker 1>one is. And so breast cancer was still viewed as

0:42:18.800 --> 0:42:23.160
<v Speaker 1>a distinct thing. Okay, and it is, I mean, and

0:42:23.200 --> 0:42:27.120
<v Speaker 1>you can see why because like there are commonalities between

0:42:27.120 --> 0:42:30.279
<v Speaker 1>some and not between others. Yeah, exactly so. But it's

0:42:30.680 --> 0:42:33.239
<v Speaker 1>what happens now. The story I'm about to tell you

0:42:33.640 --> 0:42:36.880
<v Speaker 1>is how we form the idea of cancer itself, like

0:42:37.000 --> 0:42:39.200
<v Speaker 1>the mechanism, the recognition of it.

0:42:39.520 --> 0:42:43.120
<v Speaker 4>Especially because you're like blood cancers versus solid tumors like this,

0:42:43.760 --> 0:42:45.439
<v Speaker 4>they all can look so different.

0:42:45.120 --> 0:42:46.960
<v Speaker 1>They all can look so different. So how do we

0:42:47.040 --> 0:42:48.360
<v Speaker 1>come up with cancer?

0:42:48.440 --> 0:42:49.560
<v Speaker 4>Cancer okay, okay.

0:42:50.120 --> 0:42:54.200
<v Speaker 1>In eighteen forty five, German physician Rudolph Virchow aka the

0:42:54.280 --> 0:42:57.560
<v Speaker 1>father of modern pathology, published a case report on a

0:42:57.600 --> 0:42:59.560
<v Speaker 1>fifty year old woman who had been admitted to the

0:42:59.640 --> 0:43:03.759
<v Speaker 1>hospital with edema in her legs, a swollen spleen, diarrhea,

0:43:03.880 --> 0:43:06.800
<v Speaker 1>and nose bleeds. Okay, she was treated according to the

0:43:06.800 --> 0:43:09.759
<v Speaker 1>standard of the day, which was like leeches, bleeding, purgatives,

0:43:09.840 --> 0:43:13.960
<v Speaker 1>et cetera, but she passed away. Three months later. Virtue

0:43:14.040 --> 0:43:17.280
<v Speaker 1>conducted an autopsy and found that some of her organs

0:43:17.360 --> 0:43:21.040
<v Speaker 1>were teeming with white blood cells, with hardly a red

0:43:21.080 --> 0:43:25.600
<v Speaker 1>blood cell to be found. Yeah, and it was like,

0:43:25.480 --> 0:43:27.800
<v Speaker 1>like he noted that it was like the normal ratio

0:43:27.880 --> 0:43:29.719
<v Speaker 1>of white blood cells to red blood cells had just

0:43:29.760 --> 0:43:32.920
<v Speaker 1>been reversed, and it was like the white blood cells

0:43:33.120 --> 0:43:36.600
<v Speaker 1>were so they were so numerous that they were preventing

0:43:36.640 --> 0:43:42.200
<v Speaker 1>the production of red blood cells. So to Virtue, he

0:43:42.320 --> 0:43:45.080
<v Speaker 1>was like, Okay, I've seen many white blood cells before

0:43:45.480 --> 0:43:48.319
<v Speaker 1>in like, you know, infections, but this doesn't look like that.

0:43:48.360 --> 0:43:51.280
<v Speaker 1>This is not like the thick you know, pus whatever

0:43:51.480 --> 0:43:55.560
<v Speaker 1>yellowish that happens after an injury or a festering wound.

0:43:56.160 --> 0:43:59.959
<v Speaker 1>It's just too many white blood cells that looked slightly off.

0:44:00.040 --> 0:44:02.799
<v Speaker 1>They looked mostly like normal white blood cells, but they

0:44:02.840 --> 0:44:06.440
<v Speaker 1>were not a little bit off, And so he gave

0:44:06.480 --> 0:44:08.120
<v Speaker 1>it a name, leukemia.

0:44:09.520 --> 0:44:10.200
<v Speaker 4>He named it.

0:44:10.280 --> 0:44:13.359
<v Speaker 1>He named it. It's Greek for white blood. Yeah, yeah.

0:44:13.520 --> 0:44:18.680
<v Speaker 1>And this name is was revelatory because it didn't imply

0:44:18.960 --> 0:44:22.600
<v Speaker 1>a process or a cause. It simply described what he

0:44:22.640 --> 0:44:26.680
<v Speaker 1>saw interesting white blood. And over the following years, Virtue

0:44:26.680 --> 0:44:29.879
<v Speaker 1>continued to examine and describe cases of leukemia as well

0:44:29.920 --> 0:44:34.600
<v Speaker 1>as solid tumors, and he found a common thread. Uncontrolled

0:44:34.680 --> 0:44:38.920
<v Speaker 1>cell proliferation seemed to be at the root too, many

0:44:39.280 --> 0:44:43.480
<v Speaker 1>of whatever type of cells a little bit odd, okay, yeah, okay.

0:44:44.600 --> 0:44:49.240
<v Speaker 1>And so since our bodies are made up entirely of cells,

0:44:49.239 --> 0:44:51.600
<v Speaker 1>which was kind of a relatively new concept at the time,

0:44:51.640 --> 0:44:54.319
<v Speaker 1>like cell theory had really just formalized in the early

0:44:54.360 --> 0:44:58.480
<v Speaker 1>eighteen hundreds, like eighteen thirties, Yeah, then that meant that

0:44:58.520 --> 0:45:03.000
<v Speaker 1>these malignant growths could start anywhere within our bodies neoplasia

0:45:03.280 --> 0:45:05.640
<v Speaker 1>which is what he called it, also, and that cancerous

0:45:05.640 --> 0:45:10.600
<v Speaker 1>cells could travel anywhere throughout our bodies. Virtua's framework of

0:45:10.719 --> 0:45:15.360
<v Speaker 1>uncontrolled cell proliferation, articulated in the mid nineteenth century became

0:45:15.440 --> 0:45:20.160
<v Speaker 1>the leading concept of cancer. It displaced the plethora of vague,

0:45:20.239 --> 0:45:24.479
<v Speaker 1>non mechanistic hypotheses like it's a buildup of lymph, or

0:45:24.600 --> 0:45:27.640
<v Speaker 1>it's poisons from the soil, or it's an excess of

0:45:27.719 --> 0:45:32.160
<v Speaker 1>black bile. And it still really provides the foundation for

0:45:32.239 --> 0:45:35.560
<v Speaker 1>our current understanding of this disease. It didn't explain why

0:45:35.600 --> 0:45:38.280
<v Speaker 1>cancer happened, but it gave people an image to search

0:45:38.360 --> 0:45:41.960
<v Speaker 1>for and a way to diagnose. Just too many of

0:45:42.040 --> 0:45:44.080
<v Speaker 1>one thing and it's a little bit odd.

0:45:44.840 --> 0:45:46.200
<v Speaker 4>Yeah.

0:45:46.520 --> 0:45:49.120
<v Speaker 1>With this, the field of cancer research had broken open.

0:45:49.719 --> 0:45:57.239
<v Speaker 1>Three primary, though overlapping avenues emerged. Mechanism, what's causing this, epidemiology,

0:45:57.680 --> 0:46:01.480
<v Speaker 1>who's getting it? And treatment? What do we do about it?

0:46:02.760 --> 0:46:06.279
<v Speaker 1>And Since at least the late seventeen hundreds, scientists had

0:46:06.280 --> 0:46:11.200
<v Speaker 1>identified patterns of cancer and populations, whether through environmental or

0:46:11.239 --> 0:46:15.960
<v Speaker 1>occupational exposure, like scrotal cancer and young chimney sweeps. Huh,

0:46:16.000 --> 0:46:18.600
<v Speaker 1>you don't know this story, Okay, wait for the fourth episode.

0:46:18.640 --> 0:46:24.200
<v Speaker 1>I cannot wait. It's great or familial clusters like Pierre

0:46:24.239 --> 0:46:28.880
<v Speaker 1>Broca's research on hereditary breast cancer, but these proved to

0:46:28.920 --> 0:46:31.640
<v Speaker 1>be exceptions. In the majority of cases, there was no

0:46:31.680 --> 0:46:35.719
<v Speaker 1>family history or known or distinct environmental exposure. So the

0:46:35.880 --> 0:46:39.680
<v Speaker 1>other big scientific and medical revolution at the time, microbiology

0:46:40.000 --> 0:46:44.319
<v Speaker 1>wasn't providing many answers either. While different fevers began to

0:46:44.320 --> 0:46:48.960
<v Speaker 1>be divvied up among different bacterial pathogens or microbes, they

0:46:49.000 --> 0:46:51.200
<v Speaker 1>didn't seem to be at the root of cancer, at

0:46:51.280 --> 0:46:54.800
<v Speaker 1>least not obviously. So it was our own selves causing

0:46:54.840 --> 0:46:58.719
<v Speaker 1>the problem, Just as Virtue observed in the late eighteen

0:46:58.800 --> 0:47:02.200
<v Speaker 1>hundreds and early nineteen hundred, it's improved microscopes and staining

0:47:02.239 --> 0:47:05.320
<v Speaker 1>techniques began to shed light on what it was about

0:47:05.320 --> 0:47:09.399
<v Speaker 1>our cells that was causing these issues. They look slightly off,

0:47:09.440 --> 0:47:10.640
<v Speaker 1>but what is that offness?

0:47:10.719 --> 0:47:10.879
<v Speaker 2>Right?

0:47:10.920 --> 0:47:12.680
<v Speaker 4>What is off about them?

0:47:12.800 --> 0:47:17.440
<v Speaker 1>Yeah? Yeah, our chromosomes was one thing that they observed. Basically,

0:47:17.560 --> 0:47:20.200
<v Speaker 1>something happens to the genetic markup of a cancer cell

0:47:20.280 --> 0:47:24.560
<v Speaker 1>that causes it to replicate uncontrollably, and the resulting cells

0:47:24.680 --> 0:47:29.799
<v Speaker 1>inherit that faulty genetic material, continuing this pathological cycle of

0:47:29.880 --> 0:47:33.200
<v Speaker 1>growth and metastasis. So this is when they started to

0:47:33.239 --> 0:47:35.200
<v Speaker 1>also realize that not only are we all made up

0:47:35.200 --> 0:47:39.200
<v Speaker 1>of cells, but that each cell then divides and creates

0:47:39.239 --> 0:47:41.520
<v Speaker 1>more cells, and then what is what are the instructions

0:47:41.520 --> 0:47:45.880
<v Speaker 1>that are inherited chromosomes. If it's inheriting faulty chromosomes.

0:47:45.400 --> 0:47:47.239
<v Speaker 4>Then it's going to be a faulty cell yep.

0:47:47.320 --> 0:47:49.000
<v Speaker 1>Yeah, yeah, this is how cancer grows.

0:47:49.080 --> 0:47:54.080
<v Speaker 4>Right, Yeah, what a time in research, My goodness.

0:47:54.160 --> 0:47:58.560
<v Speaker 1>But like, still, what was the initial trigger? What happened

0:47:58.600 --> 0:48:02.160
<v Speaker 1>to at the beginning to then lead to that abnormal chromosomes?

0:48:02.680 --> 0:48:05.279
<v Speaker 1>There didn't seem to be a consistent answer. There was

0:48:05.360 --> 0:48:08.880
<v Speaker 1>radiation in cancer, chimney soot and cancer cancer that ran

0:48:09.000 --> 0:48:14.480
<v Speaker 1>in families. But these diverse explanations were unsatisfying. How is

0:48:14.520 --> 0:48:18.400
<v Speaker 1>it possible that these disparate things were all resulting in

0:48:18.440 --> 0:48:23.920
<v Speaker 1>the same disease process? How then a beacon of hope.

0:48:24.400 --> 0:48:28.040
<v Speaker 1>In nineteen ten, Peyton Rouse discovered that he could transmit

0:48:28.320 --> 0:48:33.600
<v Speaker 1>cancer from one chicken to another. Oh yes. The discovery

0:48:33.640 --> 0:48:36.520
<v Speaker 1>of the Rouse sarcoma virus, which is the first cancer

0:48:36.640 --> 0:48:40.120
<v Speaker 1>virus to be discovered, kicked off a frenzy of research.

0:48:40.880 --> 0:48:44.400
<v Speaker 1>Maybe there's a virus for every cancer if we just

0:48:44.560 --> 0:48:45.200
<v Speaker 1>look hard.

0:48:45.080 --> 0:48:46.719
<v Speaker 4>Enough, just look and find it.

0:48:48.000 --> 0:48:50.520
<v Speaker 1>And for some time that seemed like it might pan out.

0:48:50.640 --> 0:48:53.440
<v Speaker 1>There was the chop Peppelloma virus was identified in nineteen

0:48:53.480 --> 0:48:56.600
<v Speaker 1>thirty three, which is that cancer causing viruses that causes

0:48:56.640 --> 0:48:59.000
<v Speaker 1>tumors and rabbits. We talk about it all the time

0:48:59.120 --> 0:49:02.160
<v Speaker 1>in our talks, but it may have led to the

0:49:02.239 --> 0:49:05.280
<v Speaker 1>jacalobe myths, these likeny growths.

0:49:05.400 --> 0:49:06.680
<v Speaker 4>Yeah, rabbits.

0:49:07.080 --> 0:49:10.439
<v Speaker 1>There were mouse viruses that caused cancer, cat viruses, and

0:49:10.680 --> 0:49:14.480
<v Speaker 1>the first human cancer virus to epstein bar virus associated

0:49:14.520 --> 0:49:17.759
<v Speaker 1>with Burkett's lymphoma, that was described in nineteen sixty four,

0:49:18.840 --> 0:49:21.279
<v Speaker 1>and so over these decades, Over this fifty years or so,

0:49:21.680 --> 0:49:24.640
<v Speaker 1>a handful of people were still working on environmental and

0:49:24.680 --> 0:49:29.600
<v Speaker 1>hereditary causes of cancer, but the majority of research funds

0:49:29.600 --> 0:49:33.360
<v Speaker 1>for basic cancer biology, which was a smaller portion of

0:49:33.360 --> 0:49:37.040
<v Speaker 1>the pie overall for cancer funding, was geared towards this

0:49:37.239 --> 0:49:39.680
<v Speaker 1>viral hypothesis of cancer sting.

0:49:40.040 --> 0:49:42.799
<v Speaker 4>Yeah, that's really really interesting to think about.

0:49:42.640 --> 0:49:47.160
<v Speaker 1>Right, And given the huge strides made in the first

0:49:47.160 --> 0:49:49.799
<v Speaker 1>half of the twentieth century when it came to the

0:49:49.840 --> 0:49:53.279
<v Speaker 1>control and prevention of infectious diseases, especially when it came

0:49:53.320 --> 0:49:56.960
<v Speaker 1>to vaccines, it makes sense that viruses were an appealing

0:49:57.080 --> 0:50:00.560
<v Speaker 1>answer to the question of why does cancer happen? Because

0:50:00.600 --> 0:50:03.359
<v Speaker 1>if you could just come up with a vaccine.

0:50:02.960 --> 0:50:04.879
<v Speaker 4>Then then that's it. Then we can be done with it.

0:50:04.880 --> 0:50:09.840
<v Speaker 1>It can be done. Yeah, well yeah, there's still you know,

0:50:09.880 --> 0:50:12.200
<v Speaker 1>you can get people to take the public buy in

0:50:12.320 --> 0:50:16.040
<v Speaker 1>and all of that. Yes, But after decades of research,

0:50:16.239 --> 0:50:19.799
<v Speaker 1>it became increasingly clear that viruses held the answer in

0:50:19.880 --> 0:50:22.960
<v Speaker 1>only a small proportion of cancers, about ten to twenty percent,

0:50:23.560 --> 0:50:26.279
<v Speaker 1>and by the mid nineteen seventies, research took on a

0:50:26.320 --> 0:50:31.880
<v Speaker 1>more balanced approach, also investigating environmental and hereditary causes of cancer.

0:50:32.560 --> 0:50:36.399
<v Speaker 1>But that era of research where like the viral hypothesis

0:50:36.480 --> 0:50:40.760
<v Speaker 1>ruled all people were also had other people were like yeah,

0:50:40.800 --> 0:50:45.120
<v Speaker 1>I know, sorry, hedging hed hedgelah. But it led to

0:50:45.360 --> 0:50:49.759
<v Speaker 1>the discovery of oncogenes. And this is a really fascinating

0:50:49.760 --> 0:50:52.600
<v Speaker 1>story which you should find out, but it's too long

0:50:52.640 --> 0:50:56.680
<v Speaker 1>to include here. But these onco genes essentially in trying

0:50:56.680 --> 0:50:58.680
<v Speaker 1>to find out what it was about this virus that

0:50:59.239 --> 0:51:03.080
<v Speaker 1>led to cancer, of what were they doing to charge themselves. Yeah,

0:51:03.200 --> 0:51:06.280
<v Speaker 1>they were like, there's this different version of a gene

0:51:06.440 --> 0:51:09.080
<v Speaker 1>that's causing it's like a mutated version of a gene

0:51:09.080 --> 0:51:12.440
<v Speaker 1>that we have, but it's causing the cell to proliferate

0:51:13.000 --> 0:51:16.800
<v Speaker 1>with no often keep growing, just go go go go go. Yeah,

0:51:16.920 --> 0:51:22.280
<v Speaker 1>and so onco genes and then later tumor suppressor genes.

0:51:22.320 --> 0:51:24.920
<v Speaker 1>That the finding of these you know, mutated forms of

0:51:24.960 --> 0:51:28.239
<v Speaker 1>normal genes that then either you know, gas pedal to

0:51:28.280 --> 0:51:30.200
<v Speaker 1>the floor or the brake is broken.

0:51:30.480 --> 0:51:30.680
<v Speaker 4>Yeah.

0:51:30.840 --> 0:51:34.520
<v Speaker 1>Yeah, they helped to unite the three main drivers thought

0:51:34.520 --> 0:51:37.880
<v Speaker 1>to cause cancer. Right, there's environmental, viral, and genetic, and

0:51:37.920 --> 0:51:41.920
<v Speaker 1>so an environmental exposure could cause mutation in a normal gene,

0:51:41.960 --> 0:51:44.640
<v Speaker 1>turning it into an oncogene. Right, gas to the floor.

0:51:45.360 --> 0:51:48.480
<v Speaker 1>A virus could insert its oncogene into the host cell's genome.

0:51:49.239 --> 0:51:52.799
<v Speaker 1>Gas to the floor. Someone could inherit a predisposition where

0:51:52.840 --> 0:51:56.680
<v Speaker 1>oncogene development is more likely, or they inherit faulty tumor

0:51:56.719 --> 0:51:59.359
<v Speaker 1>suppressor genes either gas to the floor or no break.

0:51:59.400 --> 0:52:02.719
<v Speaker 4>And we'll talk about those. Talks are about those. Yeah.

0:52:02.800 --> 0:52:05.440
<v Speaker 1>So this is how this unifying. Okay, cancer is this

0:52:05.480 --> 0:52:08.120
<v Speaker 1>thing that can happen through many different roots.

0:52:07.800 --> 0:52:10.239
<v Speaker 4>All these different mechanisms, same end result.

0:52:10.120 --> 0:52:13.800
<v Speaker 1>Same end results. Yeah, yep. But so many questions remained.

0:52:14.280 --> 0:52:17.799
<v Speaker 1>How do these mutations happen, what are the pathways? How

0:52:17.840 --> 0:52:21.320
<v Speaker 1>predictable is this process? What are the genes are involved?

0:52:21.480 --> 0:52:24.880
<v Speaker 1>Can we harness any of this information to prevent or

0:52:24.920 --> 0:52:28.600
<v Speaker 1>treat cancer. Up through the nineteen seventies, research on cancer

0:52:28.640 --> 0:52:33.720
<v Speaker 1>biology and cancer treatment was happening almost entirely separately, really

0:52:34.120 --> 0:52:37.600
<v Speaker 1>really okay, So even at a cancer conference you wouldn't

0:52:37.600 --> 0:52:41.359
<v Speaker 1>really find like a cancer geneticist attending a clinical oncologist

0:52:41.400 --> 0:52:45.279
<v Speaker 1>talk and vice versa. Just wasn't really something that could

0:52:45.360 --> 0:52:49.799
<v Speaker 1>and very siloed. And after the initial promise that chemotherapy

0:52:49.840 --> 0:52:52.720
<v Speaker 1>had shown more on that in the third episode, clinical

0:52:52.760 --> 0:52:56.040
<v Speaker 1>oncologists grew frustrated as they discovered that what worked for

0:52:56.120 --> 0:52:59.200
<v Speaker 1>one type of cancer, or even just one person's case,

0:52:59.440 --> 0:53:02.759
<v Speaker 1>you know, did work for another. This dream of a

0:53:02.920 --> 0:53:07.000
<v Speaker 1>magic bullet for cancer was slipping out of reach. Cancer

0:53:07.040 --> 0:53:11.280
<v Speaker 1>biologists validated this with their research as genetic sequencing revealed

0:53:11.320 --> 0:53:15.560
<v Speaker 1>the complex and unique pathways that drove each individual cancer

0:53:15.760 --> 0:53:19.000
<v Speaker 1>and how those pathways evolved over time. And so when

0:53:19.080 --> 0:53:23.239
<v Speaker 1>Nixon announced the War on Cancer in nineteen seventy one,

0:53:23.920 --> 0:53:26.160
<v Speaker 1>it was useful. It was really quite useful from a

0:53:26.200 --> 0:53:28.439
<v Speaker 1>funding an awareness viewpoint. It was like, you know what,

0:53:28.719 --> 0:53:30.680
<v Speaker 1>this is a thing. We're going to fight this, this

0:53:30.719 --> 0:53:33.200
<v Speaker 1>is a priority. This is a priority. We are going

0:53:33.239 --> 0:53:34.319
<v Speaker 1>to Cancer is an.

0:53:34.360 --> 0:53:36.920
<v Speaker 4>Under fund it the way that we fund war.

0:53:38.040 --> 0:53:41.040
<v Speaker 1>That is the idea. That was the idea, Yeah, but

0:53:41.120 --> 0:53:45.200
<v Speaker 1>it also had the effect of distilling this incredibly diverse

0:53:45.280 --> 0:53:49.880
<v Speaker 1>process into one disease with one mechanism, one pathway, and

0:53:49.920 --> 0:53:55.040
<v Speaker 1>thus one mythical cure. And when that cure failed to materialize,

0:53:55.080 --> 0:53:58.440
<v Speaker 1>the public grew disillusioned. There was the sense that if

0:53:58.480 --> 0:54:00.600
<v Speaker 1>we could just form a task force, we could just

0:54:00.640 --> 0:54:04.160
<v Speaker 1>task force our way through this, just throw enough resources

0:54:04.200 --> 0:54:07.200
<v Speaker 1>and expertise at this problem, then we could come up

0:54:07.200 --> 0:54:09.319
<v Speaker 1>with a solution in no time, because this is what

0:54:09.360 --> 0:54:12.239
<v Speaker 1>the Manhattan Project had done during World War Two, right, Like,

0:54:12.280 --> 0:54:16.200
<v Speaker 1>why can't we just do this? But reality didn't quite

0:54:16.400 --> 0:54:20.800
<v Speaker 1>align with these high expectations, and in nineteen ninety seven,

0:54:20.960 --> 0:54:23.760
<v Speaker 1>a controversial study came out in the New England Journal

0:54:23.760 --> 0:54:28.200
<v Speaker 1>of Medicine with the jarring title Cancer Undefeated. So this

0:54:28.320 --> 0:54:30.440
<v Speaker 1>was about, you know, twenty five, twenty six years after

0:54:30.760 --> 0:54:35.200
<v Speaker 1>Nixon's War on cancer. What was inside was even more shocking.

0:54:35.640 --> 0:54:39.480
<v Speaker 1>The report demonstrated that from nineteen seventy to nineteen ninety four,

0:54:40.200 --> 0:54:44.319
<v Speaker 1>cancer deaths had either plateaued or increased for most cancers.

0:54:44.760 --> 0:54:48.239
<v Speaker 1>In the few cases where cancer mortality had declined, it

0:54:48.280 --> 0:54:53.000
<v Speaker 1>was mostly attributed to screening and prevention. The paper was criticized,

0:54:53.080 --> 0:54:55.799
<v Speaker 1>reasonably so, because it seemed to call into question the

0:54:55.880 --> 0:54:59.120
<v Speaker 1>decades of cancer research and the millions in cancer funding.

0:55:00.040 --> 0:55:04.359
<v Speaker 1>Friend it showed was real cancer remained deadly. But what

0:55:04.440 --> 0:55:07.720
<v Speaker 1>it didn't articulate were two very important things about cancer.

0:55:07.840 --> 0:55:11.000
<v Speaker 1>Number One, cancer is not one disease, but many. A

0:55:11.040 --> 0:55:14.759
<v Speaker 1>paper like that falls into the same trap of coalescing,

0:55:15.040 --> 0:55:18.640
<v Speaker 1>this distilling into one thing. It shaves off all of

0:55:18.640 --> 0:55:21.840
<v Speaker 1>the nuance, any of the color around this thing. So

0:55:22.000 --> 0:55:24.839
<v Speaker 1>lumping all cancers together does not allow us to see

0:55:24.840 --> 0:55:29.000
<v Speaker 1>the nuance where substantial progress has absolutely been made or

0:55:29.040 --> 0:55:31.960
<v Speaker 1>where we still have a ways to go. And number two,

0:55:32.000 --> 0:55:34.280
<v Speaker 1>the other thing that it didn't really articulate about cancer

0:55:34.360 --> 0:55:37.680
<v Speaker 1>was that cancer is a disease years in the making,

0:55:38.000 --> 0:55:41.000
<v Speaker 1>both in terms of its pathology as well as our understanding.

0:55:41.600 --> 0:55:44.239
<v Speaker 1>The cigarettes that you smoked in your youth might lead

0:55:44.280 --> 0:55:48.120
<v Speaker 1>to cancer decades later, just as the cancer biology we're

0:55:48.200 --> 0:55:51.960
<v Speaker 1>uncovering now will give us insights into treatment that will

0:55:52.000 --> 0:55:56.160
<v Speaker 1>take years to develop, tests, approve, and become a standard

0:55:56.160 --> 0:55:56.440
<v Speaker 1>of care.

0:55:56.560 --> 0:55:58.279
<v Speaker 4>I think that's one of the hardest things about how

0:55:58.400 --> 0:56:00.920
<v Speaker 4>fast things feel like they're moving right now now is

0:56:00.960 --> 0:56:04.080
<v Speaker 4>that they still aren't fast enough for people today? You know,

0:56:04.280 --> 0:56:06.120
<v Speaker 4>and they are reality.

0:56:05.600 --> 0:56:09.960
<v Speaker 1>It is, it is yeah, and you know these it

0:56:10.000 --> 0:56:12.520
<v Speaker 1>will take a while for these things, these headlines to

0:56:12.560 --> 0:56:15.799
<v Speaker 1>actually become reality that people can access if you know,

0:56:16.560 --> 0:56:19.719
<v Speaker 1>there are other issues with access and but for some

0:56:19.760 --> 0:56:23.439
<v Speaker 1>treatments it has already happened. Some cancers have been completely

0:56:23.480 --> 0:56:28.520
<v Speaker 1>transformed because of our understanding and treatment development. Over its history,

0:56:28.600 --> 0:56:32.359
<v Speaker 1>cancer has been assigned so many meanings and definitions. It's

0:56:32.360 --> 0:56:36.320
<v Speaker 1>been a disease of black bile, a cellular pathology, a monster,

0:56:36.920 --> 0:56:42.040
<v Speaker 1>a genetic mutation, an enemy, a curse. In cancer's metaphors,

0:56:42.160 --> 0:56:44.960
<v Speaker 1>we see the fear and the blame that is so

0:56:45.280 --> 0:56:48.839
<v Speaker 1>human of us. In our narratives of cancer history, we

0:56:48.880 --> 0:56:53.160
<v Speaker 1>may emphasize scientific progress over failure, and in our personal

0:56:53.200 --> 0:56:57.440
<v Speaker 1>stories of cancer, we may assign villains and heroes, cause

0:56:57.480 --> 0:57:01.640
<v Speaker 1>and effect. We want cancer to be one thing, but

0:57:01.719 --> 0:57:06.000
<v Speaker 1>it isn't. It has many causes, many mechanisms, many pathways,

0:57:06.040 --> 0:57:09.319
<v Speaker 1>many beginnings, and many endings. Each time we try to

0:57:09.400 --> 0:57:13.840
<v Speaker 1>draw hard boundaries around it, cancer resists them. It demands

0:57:13.880 --> 0:57:17.360
<v Speaker 1>that we look again and reconsider, and when we do,

0:57:17.760 --> 0:57:21.280
<v Speaker 1>we find something that for me has been perspective shifting.

0:57:22.120 --> 0:57:25.400
<v Speaker 1>We find that the same cellular mechanisms that allow a

0:57:25.480 --> 0:57:29.840
<v Speaker 1>cancer to proliferate and metastasize are those that underlie our

0:57:29.880 --> 0:57:34.320
<v Speaker 1>ability to heal wounds or develop from infancy into adulthood. Yep,

0:57:34.760 --> 0:57:37.280
<v Speaker 1>we find ourselves. We find what it is to be

0:57:37.320 --> 0:57:41.960
<v Speaker 1>a multicellular being. Cancer is not a failure of ourselves.

0:57:42.040 --> 0:57:46.480
<v Speaker 1>It is a consequence of multicellular life. To understand why

0:57:46.520 --> 0:57:49.320
<v Speaker 1>cancer arises in the first place and why it's so

0:57:49.520 --> 0:57:53.320
<v Speaker 1>difficult to prevent and treat, we have to explore cancer

0:57:53.360 --> 0:57:56.720
<v Speaker 1>in an evolutionary framework. Yes we do, which is what

0:57:56.920 --> 0:57:59.720
<v Speaker 1>we'll be doing next week. But before we get there,

0:58:00.000 --> 0:58:01.840
<v Speaker 1>I'll actually have to define, like what cancer is?

0:58:01.920 --> 0:58:02.920
<v Speaker 4>What is it today?

0:58:03.280 --> 0:58:06.120
<v Speaker 1>Today? So, Aaron, what is cancer?

0:58:06.400 --> 0:58:09.400
<v Speaker 4>I would love to tell you what I can.

0:58:25.160 --> 0:58:28.320
<v Speaker 9>Hi. My name is Kara Ringstorf. I was diagnosed with

0:58:28.440 --> 0:58:32.720
<v Speaker 9>stage four colon cancer in late twenty twenty four, right

0:58:32.760 --> 0:58:37.360
<v Speaker 9>before my thirty third birthday. I had been experiencing blood

0:58:37.360 --> 0:58:40.640
<v Speaker 9>in my stool for a few years, and around three

0:58:40.640 --> 0:58:44.680
<v Speaker 9>to four doctors dismissed it as fishers or like hemorrhoids.

0:58:45.720 --> 0:58:48.120
<v Speaker 9>I was very anemic at one point and was sent

0:58:48.160 --> 0:58:51.840
<v Speaker 9>to an oncologist who was also a blood specialist, and

0:58:51.920 --> 0:58:55.480
<v Speaker 9>he told me I was just like knemic because I

0:58:55.560 --> 0:58:58.840
<v Speaker 9>was a menstruating female. About a year and a half later,

0:58:59.600 --> 0:59:02.400
<v Speaker 9>it am like there was more blood, so I told

0:59:02.440 --> 0:59:06.480
<v Speaker 9>my primary care physician that I wanted a specialist. I

0:59:06.600 --> 0:59:10.720
<v Speaker 9>had my colonoscopy and they found a four centimeter tumor

0:59:11.520 --> 0:59:15.520
<v Speaker 9>in my sigmoid colon. So I had my sigmoid colon

0:59:16.160 --> 0:59:19.400
<v Speaker 9>reception pretty soon after, and while I was in recovery,

0:59:19.480 --> 0:59:23.080
<v Speaker 9>they biopsied my liver and it turns out it had

0:59:23.160 --> 0:59:26.680
<v Speaker 9>metastasized to my liver, meaning I was Stage four. About

0:59:26.680 --> 0:59:30.320
<v Speaker 9>a month later, I had my first round of chemo. Unfortunately,

0:59:30.360 --> 0:59:32.800
<v Speaker 9>the pump they sent me home with with the five FU,

0:59:33.080 --> 0:59:35.880
<v Speaker 9>which is what my treatment plan was, gave me a

0:59:35.920 --> 0:59:38.560
<v Speaker 9>stress induced heart attack, which only happens about one to

0:59:38.600 --> 0:59:42.520
<v Speaker 9>two percent of patients. So I started back up and

0:59:43.040 --> 0:59:46.680
<v Speaker 9>switched chemo to a different schedule than what the traditional

0:59:46.720 --> 0:59:50.320
<v Speaker 9>five FU regiment is, and a couple of weeks later,

0:59:50.400 --> 0:59:55.120
<v Speaker 9>I had a liverysection in early March of twenty twenty five,

0:59:56.200 --> 1:00:00.200
<v Speaker 9>so now I'm in remission. Since then, I have of

1:00:00.880 --> 1:00:04.360
<v Speaker 9>sea tea scans and blood work done every three months.

1:00:05.560 --> 1:00:08.840
<v Speaker 9>I know that I'm in mr mission, but also with

1:00:08.920 --> 1:00:12.080
<v Speaker 9>the reoccurrence rate and everything, it still kind of feels

1:00:12.200 --> 1:00:13.640
<v Speaker 9>like a death sentence for me.

1:00:15.960 --> 1:00:17.960
<v Speaker 10>Hi. My name is Rachel, and today I would like

1:00:18.000 --> 1:00:20.720
<v Speaker 10>to share my twin sister, Leslie's story. We had a

1:00:20.720 --> 1:00:23.320
<v Speaker 10>standard sibling relationship growing up and she was my best

1:00:23.360 --> 1:00:26.720
<v Speaker 10>friend as we entered into early adulthood. The summer we

1:00:26.800 --> 1:00:29.960
<v Speaker 10>turned twenty one, she was diagnosed with uvula melanoma, a

1:00:30.040 --> 1:00:32.920
<v Speaker 10>rare tumor growing in her eye. She had almost none

1:00:32.920 --> 1:00:35.560
<v Speaker 10>of the risk factors, was young, healthy, and active, but

1:00:35.680 --> 1:00:39.960
<v Speaker 10>cancer doesn't care about those things. Initial treatment included radiation

1:00:40.040 --> 1:00:42.600
<v Speaker 10>black therapy to kill the blood supply and shrink the tumor,

1:00:42.880 --> 1:00:46.200
<v Speaker 10>and she had successful treatment. We were thankful to live

1:00:46.200 --> 1:00:48.800
<v Speaker 10>in an area with access to excellent medical care, including

1:00:48.840 --> 1:00:53.200
<v Speaker 10>her ophthalmologist, doctor Oliver. Follow Up included yearly scans that

1:00:53.240 --> 1:00:56.480
<v Speaker 10>she went to diligently. Leslie went on to graduate with

1:00:56.520 --> 1:00:59.200
<v Speaker 10>her Bachelor of Science and Kinesiology and health promotion, and

1:00:59.240 --> 1:01:02.400
<v Speaker 10>she became a doctor or physical therapy. She got married

1:01:02.400 --> 1:01:04.360
<v Speaker 10>and lived life to the fulls for the next ten years.

1:01:05.560 --> 1:01:07.800
<v Speaker 10>In her free time, she loved skiing and hiking, which

1:01:07.840 --> 1:01:11.200
<v Speaker 10>are typical of a Colorado native. For skiing, she gravitated

1:01:11.200 --> 1:01:14.120
<v Speaker 10>towards the most technical runs like Christmas Tree Bowl and Steamboat.

1:01:14.760 --> 1:01:17.360
<v Speaker 10>For hikings, she also gravitated towards technical routes and was

1:01:17.400 --> 1:01:21.000
<v Speaker 10>able to summit over forty of Colorado's fourteen ers, including

1:01:21.040 --> 1:01:23.480
<v Speaker 10>some of the most challenging Class four routes like Beer Peak.

1:01:24.280 --> 1:01:26.919
<v Speaker 10>I haven't summitted nearly that many, but she, my dad,

1:01:26.960 --> 1:01:29.480
<v Speaker 10>and her husband slowly kept knocking peak after Peak off

1:01:29.520 --> 1:01:32.880
<v Speaker 10>the list. Then shortly after our thirty first birthday, she

1:01:32.920 --> 1:01:35.960
<v Speaker 10>had her son, and in early summer, the unimaginable happened,

1:01:35.960 --> 1:01:38.680
<v Speaker 10>and she was diagnosed with metastatic y vi la melanoma

1:01:38.680 --> 1:01:41.800
<v Speaker 10>in her liver after having a clear scan the fall prior.

1:01:42.920 --> 1:01:45.320
<v Speaker 10>While doctors were again able to act quickly, the cancer

1:01:45.400 --> 1:01:48.000
<v Speaker 10>was growing too rapidly for successful treatment, and she passed

1:01:48.040 --> 1:01:51.680
<v Speaker 10>away less than eight weeks after this diagnosis. I just

1:01:51.760 --> 1:01:55.040
<v Speaker 10>celebrated my seventh birthday without her, surrounded by family skiing

1:01:55.040 --> 1:01:58.160
<v Speaker 10>in the mountains. Her husband has since remarried, and I

1:01:58.200 --> 1:02:00.200
<v Speaker 10>am thankful her son has a mother to grow up with.

1:02:01.480 --> 1:02:03.720
<v Speaker 10>I'm now a mom to three, including a set of twins.

1:02:04.360 --> 1:02:06.520
<v Speaker 10>There's no roadmap to grief, and I've learned a lot

1:02:06.560 --> 1:02:09.080
<v Speaker 10>about giving others grace and understanding because we don't know

1:02:09.080 --> 1:02:11.640
<v Speaker 10>what they might be working through. I also think of

1:02:11.640 --> 1:02:14.880
<v Speaker 10>friends and family navigating their own journeys with cancer, and

1:02:14.920 --> 1:02:17.640
<v Speaker 10>as a biomedical engineer, I use my sister's story as

1:02:17.720 --> 1:02:21.400
<v Speaker 10>motivation to continue to engineer medical devices that allow surgeons

1:02:21.400 --> 1:02:24.480
<v Speaker 10>to have better patient outcomes. I'm also choosing to live

1:02:24.480 --> 1:02:26.880
<v Speaker 10>life to the fullest, just like Leslie, and I'm thankful

1:02:26.920 --> 1:02:30.320
<v Speaker 10>to have a supportive husband and family. Leslie didn't want

1:02:30.360 --> 1:02:32.800
<v Speaker 10>to be defined by her diagnosis. She wanted to be

1:02:32.840 --> 1:02:34.920
<v Speaker 10>defined by the things she did and the patient she

1:02:34.960 --> 1:02:39.760
<v Speaker 10>interacted with. She was a wife, mother, sister, daughter, avid

1:02:39.800 --> 1:02:43.280
<v Speaker 10>skier and hiker, and a doctor. Leslie, I love you

1:02:43.320 --> 1:03:16.280
<v Speaker 10>and miss you.

1:03:08.560 --> 1:03:11.920
<v Speaker 4>So Erin. Obviously, you covered a lot of ground in

1:03:11.920 --> 1:03:14.360
<v Speaker 4>that history section. Thank you very much. I really enjoyed it.

1:03:14.840 --> 1:03:16.640
<v Speaker 4>But we do still have quite a bit to cover

1:03:17.760 --> 1:03:21.040
<v Speaker 4>in terms of what we mean when we talk about

1:03:21.040 --> 1:03:24.240
<v Speaker 4>cancers today, and so that's what I'm going to try

1:03:24.240 --> 1:03:27.160
<v Speaker 4>and get into right now. And there are actually quite

1:03:27.200 --> 1:03:30.880
<v Speaker 4>a number of different definitions depending on what organization you're

1:03:30.920 --> 1:03:33.960
<v Speaker 4>looking at. But they do all boil down to this

1:03:34.360 --> 1:03:40.680
<v Speaker 4>same general concept, which is abnormal growth. Right, cancer is

1:03:40.960 --> 1:03:45.240
<v Speaker 4>an aberition of some kind. It is abnormal, it's atypical,

1:03:45.560 --> 1:03:50.600
<v Speaker 4>it's out of control, it's uncontrollable growth in some way.

1:03:51.280 --> 1:03:54.280
<v Speaker 4>So one technical definition that I will put forth comes

1:03:54.320 --> 1:03:58.800
<v Speaker 4>from the National Cancer Institute, which says, quote, cancer is

1:03:58.840 --> 1:04:02.560
<v Speaker 4>a disease in which some of the body's cells grow

1:04:02.880 --> 1:04:07.760
<v Speaker 4>uncontrollably and spread to other parts of the body. Now,

1:04:07.760 --> 1:04:11.080
<v Speaker 4>I just like side note here because some of the

1:04:11.120 --> 1:04:15.720
<v Speaker 4>definitions of cancer very explicitly say cancer is a group

1:04:15.800 --> 1:04:20.200
<v Speaker 4>of diseases, which and other definitions say cancer is a disease.

1:04:20.240 --> 1:04:22.720
<v Speaker 4>And I just think that that's a really interesting like

1:04:23.120 --> 1:04:25.280
<v Speaker 4>that that is still something that I wouldn't say is

1:04:25.320 --> 1:04:27.640
<v Speaker 4>like up for debate, but is just like a part

1:04:27.680 --> 1:04:29.880
<v Speaker 4>of how we define cancer where some groups are going

1:04:29.920 --> 1:04:32.760
<v Speaker 4>to define it more as multiple different diseases and some

1:04:32.840 --> 1:04:34.960
<v Speaker 4>are going to say, like we're lumping all of cancer

1:04:35.040 --> 1:04:39.080
<v Speaker 4>as one thing, right, with many different pathways and many

1:04:39.120 --> 1:04:42.040
<v Speaker 4>different like ways that it's going to turn out. Essentially

1:04:42.880 --> 1:04:44.160
<v Speaker 4>it's interesting, well.

1:04:44.000 --> 1:04:47.200
<v Speaker 1>And it's like there's a deliberate choice there, Yes, exactly

1:04:47.240 --> 1:04:47.920
<v Speaker 1>what does that.

1:04:48.000 --> 1:04:50.360
<v Speaker 4>Mean, what does that mean? I also read it really interesting.

1:04:50.400 --> 1:04:52.920
<v Speaker 4>I'm so off script right now, but I read a

1:04:52.960 --> 1:04:55.640
<v Speaker 4>really interesting paper from twenty twenty three that was like

1:04:55.680 --> 1:04:58.600
<v Speaker 4>a we're proposing a new definition for cancer. That was

1:04:58.800 --> 1:05:01.080
<v Speaker 4>much and it was an int higher paper that was

1:05:01.120 --> 1:05:04.840
<v Speaker 4>an explanation for their one sentence definition, like word by word,

1:05:04.880 --> 1:05:07.240
<v Speaker 4>this is why we chose of instead of buy and

1:05:07.280 --> 1:05:08.760
<v Speaker 4>stuff like that that you would love it.

1:05:08.800 --> 1:05:09.400
<v Speaker 1>I would love that.

1:05:09.640 --> 1:05:12.960
<v Speaker 4>But they really focused a lot on the evolution concept,

1:05:12.960 --> 1:05:15.360
<v Speaker 4>which we're going to talk more about next week. But

1:05:15.400 --> 1:05:17.800
<v Speaker 4>it's a great paper. I'll link to it, please. So

1:05:18.320 --> 1:05:23.480
<v Speaker 4>the point is the point is that uncontrollable cell growth, yes,

1:05:23.800 --> 1:05:27.320
<v Speaker 4>that spreads to other parts of our bodies. Okay, just

1:05:27.360 --> 1:05:29.640
<v Speaker 4>pause and don't ask me any questions, sure, because I

1:05:29.680 --> 1:05:33.120
<v Speaker 4>will tell you that. A big question that arises when

1:05:33.120 --> 1:05:37.880
<v Speaker 4>I hear that particular definition is like how why? How?

1:05:38.080 --> 1:05:41.520
<v Speaker 4>How are cells growing uncontrollably? How are they spreading to

1:05:41.640 --> 1:05:44.240
<v Speaker 4>other parts of our body? I'm not going to answer

1:05:44.240 --> 1:05:45.240
<v Speaker 4>that question this week.

1:05:46.240 --> 1:05:47.320
<v Speaker 1>Can I ask a question?

1:05:47.440 --> 1:05:49.720
<v Speaker 4>Yeah, but I just want you to know if it's

1:05:49.720 --> 1:05:50.600
<v Speaker 4>that I won't answer it.

1:05:50.680 --> 1:05:53.360
<v Speaker 1>No, No, No, I kind of know some of that.

1:05:53.560 --> 1:05:54.240
<v Speaker 4>Yes, I know you do.

1:05:54.440 --> 1:05:58.439
<v Speaker 1>But spread spread is that?

1:05:58.640 --> 1:06:01.280
<v Speaker 4>So that is obviously that is a big I'll talk

1:06:01.280 --> 1:06:03.880
<v Speaker 4>a lot about that this week. Yes, Okay, that is

1:06:03.920 --> 1:06:06.160
<v Speaker 4>a big part of cancer and that I will talk

1:06:06.200 --> 1:06:09.760
<v Speaker 4>about this week. Okay, spreads to other part is.

1:06:08.680 --> 1:06:12.880
<v Speaker 1>A necessary inclusion in that definition. H fascinating.

1:06:13.000 --> 1:06:16.000
<v Speaker 4>We'll get there, we'll get there. But the question of

1:06:16.040 --> 1:06:18.520
<v Speaker 4>how this happens is what I'm going to focus more

1:06:18.520 --> 1:06:23.000
<v Speaker 4>on next week's episode. But this week I'm gonna just

1:06:23.200 --> 1:06:25.600
<v Speaker 4>kind of take for granted that we all understand the

1:06:25.640 --> 1:06:28.400
<v Speaker 4>idea of a cancer because we've known someone who has

1:06:28.440 --> 1:06:30.960
<v Speaker 4>had cancer, et cetera. And what I want to dig

1:06:30.960 --> 1:06:32.880
<v Speaker 4>a little bit deeper into is what I would call

1:06:32.920 --> 1:06:35.400
<v Speaker 4>maybe the kind of clinical aspects of how we deal

1:06:35.400 --> 1:06:39.400
<v Speaker 4>with cancers today, how we define them, how we classify them,

1:06:39.760 --> 1:06:42.880
<v Speaker 4>and then broad strokes on sort of how we're diagnosing

1:06:43.120 --> 1:06:47.560
<v Speaker 4>and you know, grouping different kinds of cancers. Okay, and

1:06:47.600 --> 1:06:51.040
<v Speaker 4>then next week is more the biology of what's happening. Cool.

1:06:51.240 --> 1:06:51.640
<v Speaker 1>Great.

1:06:52.120 --> 1:06:55.440
<v Speaker 4>So the first way that we have to classify cancers,

1:06:55.480 --> 1:06:57.480
<v Speaker 4>and I think that we do this kind of almost

1:06:57.520 --> 1:07:01.040
<v Speaker 4>intuitively when we talk about cancers, is what organ is

1:07:01.040 --> 1:07:03.920
<v Speaker 4>your cancer coming from? And that is actually the first

1:07:03.920 --> 1:07:06.320
<v Speaker 4>way that medicine has to classify a cancer too, it's

1:07:06.360 --> 1:07:09.520
<v Speaker 4>primary side of origin. So where did those cells initially

1:07:09.520 --> 1:07:12.560
<v Speaker 4>come from? Where they lung cells, where they breast cells,

1:07:12.600 --> 1:07:15.720
<v Speaker 4>where they liver cells, Where in the body did this

1:07:15.840 --> 1:07:19.760
<v Speaker 4>tumor first begin? Oh, I have so many questions already, Okay, okay,

1:07:20.200 --> 1:07:22.400
<v Speaker 4>And we do this for a lot of different reasons,

1:07:22.440 --> 1:07:26.280
<v Speaker 4>but it's in part to figure out where it first started. Yeah,

1:07:26.320 --> 1:07:30.320
<v Speaker 4>and also because pancreatic cancer acts very differently than breast cancer,

1:07:30.400 --> 1:07:32.560
<v Speaker 4>and so we need to know what we're dealing with, right,

1:07:33.360 --> 1:07:36.040
<v Speaker 4>which also act differently, by the way, than blood cancers

1:07:36.080 --> 1:07:39.120
<v Speaker 4>like leukemias and lymphomas. These are all very distinct types

1:07:39.160 --> 1:07:43.160
<v Speaker 4>of cancers. Once we have figured out the organ, like

1:07:43.240 --> 1:07:46.160
<v Speaker 4>the tissue that it came from, that is not the

1:07:46.320 --> 1:07:49.680
<v Speaker 4>end because not all breast cancers are the same, not

1:07:49.760 --> 1:07:53.720
<v Speaker 4>all lung cancers are the same. And so the next

1:07:53.720 --> 1:07:56.280
<v Speaker 4>part that we have to do is figure out what

1:07:56.920 --> 1:08:01.880
<v Speaker 4>tissue type it came from within that organ.

1:08:02.040 --> 1:08:03.480
<v Speaker 1>Okay, what part of the lung?

1:08:03.720 --> 1:08:08.480
<v Speaker 4>What part? Yeah, So cancers that come from our epithelial cells,

1:08:08.600 --> 1:08:10.760
<v Speaker 4>and we've talked a lot about epithelial cells on this podcast,

1:08:10.760 --> 1:08:13.440
<v Speaker 4>but they're the cells that line all of our body surfaces.

1:08:13.880 --> 1:08:16.639
<v Speaker 4>So they're like the inside of ducts in your breast.

1:08:16.840 --> 1:08:20.799
<v Speaker 4>They are the insides of all of our blood vessels.

1:08:20.800 --> 1:08:23.799
<v Speaker 4>They are the cells that are like lining and making

1:08:23.880 --> 1:08:27.720
<v Speaker 4>up the inner parts of our body surfaces. These are

1:08:27.720 --> 1:08:32.080
<v Speaker 4>called carcinomas. And so if you ever hear carcinoma, that

1:08:32.120 --> 1:08:34.680
<v Speaker 4>means that it came from epithelial cells. This accounts for

1:08:34.760 --> 1:08:38.439
<v Speaker 4>like over ninety percent of solid cancers we'll get there, okay,

1:08:38.479 --> 1:08:42.240
<v Speaker 4>of humans, And you further can divide it from there

1:08:42.280 --> 1:08:44.960
<v Speaker 4>because there are many different types of epithelial cells. So

1:08:45.000 --> 1:08:47.800
<v Speaker 4>you might have a squamous cell carcinoma that came from

1:08:47.840 --> 1:08:52.240
<v Speaker 4>these flat like diski shaped cells, or you might have

1:08:52.320 --> 1:08:56.960
<v Speaker 4>an adinocarcinoma, which comes from these glandular cells. And some cancers,

1:08:57.000 --> 1:09:00.040
<v Speaker 4>like breast cancer, for example, most are all adno carcinomas.

1:09:00.080 --> 1:09:02.680
<v Speaker 4>But we don't necessarily call them that. We distinct them

1:09:02.680 --> 1:09:04.400
<v Speaker 4>by did it come from the duct, did it come

1:09:04.439 --> 1:09:07.000
<v Speaker 4>from the lapule. There's a lot of different types. We

1:09:07.080 --> 1:09:08.120
<v Speaker 4>get really specific.

1:09:08.240 --> 1:09:14.600
<v Speaker 1>Okay, it's wild. I know how many different sub small.

1:09:14.320 --> 1:09:17.120
<v Speaker 4>Cell non small cells, squamous cell. I don't know, like

1:09:17.120 --> 1:09:20.479
<v Speaker 4>there's so many different types of these, even just within

1:09:20.640 --> 1:09:25.559
<v Speaker 4>the carcinoma category. Aside from that, cancers can also arise

1:09:25.640 --> 1:09:28.920
<v Speaker 4>from non epithelial tissues, and these would be our connective

1:09:29.040 --> 1:09:34.960
<v Speaker 4>tissue cancers. Okay, so sarcomas, bone cancers, those kinds of

1:09:34.960 --> 1:09:37.920
<v Speaker 4>things are called sarcomas, and those are actually a really

1:09:38.000 --> 1:09:42.679
<v Speaker 4>wide range as well. So for example, a mesothelioma which

1:09:43.000 --> 1:09:45.960
<v Speaker 4>listened to our asbestos episode for more detail. But a

1:09:46.040 --> 1:09:48.479
<v Speaker 4>mesothelioma we think of as a lung cancer, it's not

1:09:48.560 --> 1:09:51.400
<v Speaker 4>a lung cancer. It's a cancer of the lining of

1:09:51.520 --> 1:09:55.160
<v Speaker 4>the lung, which is a connective tissue. So even though

1:09:55.200 --> 1:10:00.320
<v Speaker 4>it gets a special name mesothelioma, it is technically a sarcoma. Whoa,

1:10:00.520 --> 1:10:03.200
<v Speaker 4>I know, I'm getting technical, but it's fun for me.

1:10:03.560 --> 1:10:05.840
<v Speaker 1>I think it well, I mean, I think it's helpful

1:10:06.000 --> 1:10:09.200
<v Speaker 1>to understand that it truly can arise anywhere anywhere, and

1:10:09.240 --> 1:10:11.640
<v Speaker 1>the side of origin and the type of origin and

1:10:11.640 --> 1:10:13.920
<v Speaker 1>blah blah blah all influences the path that the cancer

1:10:13.960 --> 1:10:14.519
<v Speaker 1>could take.

1:10:14.360 --> 1:10:17.840
<v Speaker 4>Exactly, because it all means that these cells initially were

1:10:17.880 --> 1:10:20.479
<v Speaker 4>acting in one particular way, and so that's going to

1:10:20.520 --> 1:10:22.760
<v Speaker 4>tell us something about how they might act as they

1:10:22.760 --> 1:10:27.800
<v Speaker 4>become cancer cells. Then there's also cancers that originate in

1:10:28.080 --> 1:10:32.200
<v Speaker 4>our bones, like our blood based cancers rather right and

1:10:32.960 --> 1:10:36.320
<v Speaker 4>bone marrow yes, thank you whoa aaron? So that would

1:10:36.360 --> 1:10:40.240
<v Speaker 4>be like a leukemias, lymphomas, myelomas, which are all different

1:10:40.280 --> 1:10:45.880
<v Speaker 4>types of blood cell cancers. Okay. Then there's also more

1:10:45.920 --> 1:10:48.760
<v Speaker 4>specific ones you can get like retino blastoma which is

1:10:48.800 --> 1:10:52.120
<v Speaker 4>in the retina of your eye, glioblastomas which are in

1:10:52.160 --> 1:10:55.600
<v Speaker 4>your brain, which I think technically might fall under sarcoma,

1:10:55.640 --> 1:10:59.200
<v Speaker 4>but they're so specialized that there I don't know if

1:10:59.240 --> 1:11:02.280
<v Speaker 4>they actually technically count as a sarcoma because they again

1:11:02.320 --> 1:11:05.880
<v Speaker 4>are just so specialized that it's your brain cells. So

1:11:06.200 --> 1:11:07.559
<v Speaker 4>there's a lot of different ways that we have to

1:11:07.560 --> 1:11:11.160
<v Speaker 4>classify it at the beginning. But if we then go back,

1:11:11.200 --> 1:11:13.639
<v Speaker 4>so knowing that if we go back to our definition

1:11:13.720 --> 1:11:17.720
<v Speaker 4>of cancer of these cells that are growing in an

1:11:17.800 --> 1:11:22.120
<v Speaker 4>uncontrolled way, that are then spreading to part of our body,

1:11:22.880 --> 1:11:27.519
<v Speaker 4>part of this definition is that it's abnormal growth. So

1:11:28.400 --> 1:11:31.640
<v Speaker 4>what is it that makes these abnormal?

1:11:33.080 --> 1:11:34.960
<v Speaker 1>It's a great question, It's a really great question.

1:11:35.000 --> 1:11:37.559
<v Speaker 4>And mechanistically we'll get a little bit more into detail

1:11:37.640 --> 1:11:40.559
<v Speaker 4>on that next week. But one thing to know is

1:11:40.560 --> 1:11:45.240
<v Speaker 4>that cancers grow in these like disorganized masses, especially when

1:11:45.240 --> 1:11:48.280
<v Speaker 4>we're talking about solid tumors, right, so everything but the

1:11:48.320 --> 1:11:52.680
<v Speaker 4>blood cancers, and we call these tumors like that's the

1:11:52.760 --> 1:11:55.599
<v Speaker 4>name that we call these clumps of cells. But not

1:11:55.840 --> 1:12:02.320
<v Speaker 4>all tumors are cancer, right. In medicine, we call non

1:12:02.400 --> 1:12:06.280
<v Speaker 4>cancerous tumors benign. And it's not a great word.

1:12:06.280 --> 1:12:07.720
<v Speaker 1>It's not a great word. We talked about this in

1:12:07.840 --> 1:12:08.280
<v Speaker 1>enemage for you.

1:12:08.479 --> 1:12:11.920
<v Speaker 4>We did, yeah, we did, because in medicine, benign does

1:12:11.960 --> 1:12:14.719
<v Speaker 4>not mean good. It does not mean chill, it doesn't

1:12:14.760 --> 1:12:18.040
<v Speaker 4>mean don't worry about it. It means that this tumor

1:12:18.240 --> 1:12:22.880
<v Speaker 4>is not going to metastasize. And that is really the

1:12:23.000 --> 1:12:27.120
<v Speaker 4>key that makes cancers cancers. It's not just that they're

1:12:27.120 --> 1:12:31.160
<v Speaker 4>growing these disorganized clumps of cells. It's not just all

1:12:31.160 --> 1:12:34.160
<v Speaker 4>these things. It's also that they are spreading, and they

1:12:34.240 --> 1:12:38.040
<v Speaker 4>spread in a lot of different ways. The thing that

1:12:38.120 --> 1:12:44.240
<v Speaker 4>makes cancer so deadly is this ability to invade our bodies. First,

1:12:44.640 --> 1:12:48.240
<v Speaker 4>they're invading past what we would call tissue level barriers,

1:12:48.960 --> 1:12:51.880
<v Speaker 4>which means that a cancer might start within the duct

1:12:51.920 --> 1:12:54.559
<v Speaker 4>cells of your breast. But then it's going to invade

1:12:54.640 --> 1:12:59.280
<v Speaker 4>through the lining of those ducks and into the surrounding tissue,

1:12:59.840 --> 1:13:02.800
<v Speaker 4>and then it will break off pieces of itself and

1:13:02.840 --> 1:13:06.400
<v Speaker 4>it will travel whether through your lymph system into your

1:13:06.479 --> 1:13:09.880
<v Speaker 4>lymph nodes or through your bloodstream to distant organs and

1:13:09.960 --> 1:13:13.320
<v Speaker 4>set up shop there. And that is what we call metastases,

1:13:13.760 --> 1:13:16.559
<v Speaker 4>those little bits of pieces that travel and make new

1:13:16.600 --> 1:13:17.960
<v Speaker 4>tumors at distant sites.

1:13:19.000 --> 1:13:25.439
<v Speaker 1>So, yeah, uh, spread or potential to spread? And what

1:13:25.600 --> 1:13:30.320
<v Speaker 1>is that quality or characteristic that allows for mobility.

1:13:30.680 --> 1:13:34.759
<v Speaker 4>That's a great question. I don't know, Okay, I don't

1:13:34.800 --> 1:13:36.400
<v Speaker 4>know if we fully understand that.

1:13:36.640 --> 1:13:39.000
<v Speaker 1>But like so if you're trying to say, is this

1:13:39.120 --> 1:13:44.960
<v Speaker 1>a benign growth or a cancerous growth? Yeah, has what

1:13:45.479 --> 1:13:46.280
<v Speaker 1>how do you distinguish?

1:13:46.360 --> 1:13:50.280
<v Speaker 4>That's a great question. They're looking at the We'll talk

1:13:50.280 --> 1:13:52.479
<v Speaker 4>a lot more about all of the other like cell

1:13:52.760 --> 1:13:55.000
<v Speaker 4>markers and things that we see on how these cells

1:13:55.040 --> 1:13:58.320
<v Speaker 4>behave in cancer. Yeah, if that makes sense a little

1:13:58.320 --> 1:14:01.799
<v Speaker 4>bit next weeks exactly the hallmarks of like how cancer

1:14:01.840 --> 1:14:04.040
<v Speaker 4>cells all behave. But and so a lot of it

1:14:04.080 --> 1:14:05.599
<v Speaker 4>is that it's looking at all of these things, and

1:14:05.600 --> 1:14:08.680
<v Speaker 4>I think it's also looking at the disorganization of the

1:14:08.760 --> 1:14:14.080
<v Speaker 4>structure where benign tumors are less likely to be super disorganized,

1:14:14.200 --> 1:14:17.479
<v Speaker 4>though they might be a little bit disorganized, okay, compared

1:14:17.560 --> 1:14:20.599
<v Speaker 4>to malignant tumors. So things that are going to be spreading.

1:14:21.479 --> 1:14:25.759
<v Speaker 4>And I think too, it's I think that most of

1:14:25.880 --> 1:14:29.720
<v Speaker 4>these growths now we have well characterized, so we know

1:14:30.040 --> 1:14:33.120
<v Speaker 4>if you look at this type of tumor, it is

1:14:33.200 --> 1:14:36.160
<v Speaker 4>not likely to spread, Whereas if you look at this

1:14:36.280 --> 1:14:38.599
<v Speaker 4>type of tumor, it is likely to spread. And there

1:14:38.640 --> 1:14:41.639
<v Speaker 4>are some that can sometimes hedge that line where they

1:14:41.680 --> 1:14:44.920
<v Speaker 4>are not cancerous, but they might have the potential to

1:14:45.040 --> 1:14:46.679
<v Speaker 4>become cancerous. Okay.

1:14:46.920 --> 1:14:50.840
<v Speaker 1>Another question from the class endometriosis.

1:14:50.960 --> 1:14:53.559
<v Speaker 4>Oh, I knew you were going to ask. I know,

1:14:53.600 --> 1:14:54.400
<v Speaker 4>I know, I have to.

1:14:54.520 --> 1:14:58.639
<v Speaker 1>I mean, you can find cells anywhere in the body

1:14:58.760 --> 1:15:02.719
<v Speaker 1>and it can form tishoe, it could grow to shoe anywhere. Yeah,

1:15:02.760 --> 1:15:05.280
<v Speaker 1>so how is that not it's just as a cancer.

1:15:05.400 --> 1:15:07.920
<v Speaker 4>It's no we talked to question. But it's a really

1:15:08.000 --> 1:15:10.360
<v Speaker 4>good question. And I think honestly, doing this research for

1:15:10.400 --> 1:15:12.719
<v Speaker 4>this episode made me go back and ask that question

1:15:12.760 --> 1:15:15.479
<v Speaker 4>myself because I was like, it doesn't kind of make sense.

1:15:15.520 --> 1:15:18.200
<v Speaker 4>This is one of the biggest hallmarks and it's because

1:15:18.560 --> 1:15:21.880
<v Speaker 4>the endometrial tissue that we find in endometriosis doesn't meet

1:15:21.880 --> 1:15:25.520
<v Speaker 4>all of the other hallmarks of cancer. It's not necessarily disorganized,

1:15:25.560 --> 1:15:29.559
<v Speaker 4>it's not replicating indefinitely. It's replicating in a way that

1:15:29.680 --> 1:15:32.120
<v Speaker 4>is in sync with a menstrual cycle and things like that, Like,

1:15:32.160 --> 1:15:36.040
<v Speaker 4>it's not just going wild. I would say, it's a

1:15:36.200 --> 1:15:40.200
<v Speaker 4>valid question to think, where is this line blurrier than

1:15:40.240 --> 1:15:43.320
<v Speaker 4>we think, right? And I think maybe, But I'm just

1:15:43.360 --> 1:15:43.880
<v Speaker 4>going with what.

1:15:43.800 --> 1:15:45.240
<v Speaker 1>I guessh in the boundaries again.

1:15:45.479 --> 1:15:49.320
<v Speaker 4>Yeah, Yeah, endometrosis is a wild beast. It is, especially

1:15:49.800 --> 1:15:52.839
<v Speaker 4>in the context of this. Yeah, because yeah, they spread everywhere.

1:15:53.360 --> 1:15:56.479
<v Speaker 4>M but that's what cancers do. And because of this,

1:15:58.880 --> 1:16:04.880
<v Speaker 4>metastases are the reason why. The next step in defining

1:16:04.920 --> 1:16:08.880
<v Speaker 4>our cancers is figuring out how far it has already spread.

1:16:09.439 --> 1:16:11.960
<v Speaker 4>And so we do this through a process called cancer staging.

1:16:12.000 --> 1:16:14.160
<v Speaker 4>So once someone has a cancer and we know where

1:16:14.160 --> 1:16:15.760
<v Speaker 4>it came from, we know what kinds of cells it

1:16:15.800 --> 1:16:17.479
<v Speaker 4>came from, we need to figure out how far it

1:16:17.520 --> 1:16:20.800
<v Speaker 4>has gone, and so we do this through staging is

1:16:20.840 --> 1:16:24.680
<v Speaker 4>often called like TNM staging, which I'll tell you what

1:16:24.720 --> 1:16:27.599
<v Speaker 4>it all stands for. And so first, the first way

1:16:28.120 --> 1:16:30.559
<v Speaker 4>asterisk on this. But the first way that cancers tend

1:16:30.600 --> 1:16:33.559
<v Speaker 4>to spread is locally, so from like the inner lining

1:16:33.600 --> 1:16:37.759
<v Speaker 4>of your bladder, through the muscle wall or something like that. Okay,

1:16:37.920 --> 1:16:41.919
<v Speaker 4>So how far a cancer has invaded within the tissue

1:16:41.960 --> 1:16:45.960
<v Speaker 4>that it's from is the first component of that cancer,

1:16:46.000 --> 1:16:48.519
<v Speaker 4>and that's the t in the TNM framework.

1:16:48.760 --> 1:16:49.160
<v Speaker 1>Okay.

1:16:49.360 --> 1:16:54.640
<v Speaker 4>So for example, you could have something called ductyl carcinoma insto,

1:16:55.360 --> 1:16:58.360
<v Speaker 4>These are cancer cells, but they have not yet left

1:16:58.560 --> 1:17:03.759
<v Speaker 4>that duct, right, So that's like a stage zero cancer. Okay,

1:17:03.880 --> 1:17:06.800
<v Speaker 4>same thing with bladder cancer. You might have and this

1:17:06.840 --> 1:17:08.960
<v Speaker 4>is true for any cancer, but bladder cancer. You might

1:17:09.000 --> 1:17:12.040
<v Speaker 4>have it that's just within the lining of the bladder

1:17:12.360 --> 1:17:14.920
<v Speaker 4>and hasn't yet invaded into the muscle. Or you might

1:17:14.920 --> 1:17:17.680
<v Speaker 4>have what's considered muscle invasive bladder cancer. So now it's

1:17:17.680 --> 1:17:20.080
<v Speaker 4>made it through the muscle, Okay, have the bladder wall.

1:17:20.200 --> 1:17:24.519
<v Speaker 1>How how much variation is there in terms of like

1:17:24.640 --> 1:17:26.599
<v Speaker 1>the thickness of these different layers.

1:17:26.680 --> 1:17:28.919
<v Speaker 4>Oh that's a great question, huge amounts.

1:17:29.040 --> 1:17:29.320
<v Speaker 1>Okay.

1:17:29.360 --> 1:17:29.559
<v Speaker 2>Yeah.

1:17:29.600 --> 1:17:32.000
<v Speaker 4>You think of like the duct of a breast, Like

1:17:32.040 --> 1:17:33.960
<v Speaker 4>a breast duct is going to be like a couple

1:17:34.080 --> 1:17:36.959
<v Speaker 4>sells thick, whereas the lining of your bladder is quite thick.

1:17:36.880 --> 1:17:39.640
<v Speaker 1>Right, yeah, And so how does like, does that have

1:17:39.680 --> 1:17:41.000
<v Speaker 1>any bearing on staging?

1:17:42.800 --> 1:17:46.200
<v Speaker 4>It's all I mean, it's all part of the staging process,

1:17:46.320 --> 1:17:48.679
<v Speaker 4>but like does what does it mean for prognosis and things?

1:17:48.720 --> 1:17:51.120
<v Speaker 4>That's such a I know, I can't answer that question,

1:17:51.200 --> 1:17:53.360
<v Speaker 4>I know, I know. So then the next part of

1:17:53.360 --> 1:17:57.679
<v Speaker 4>staging is n which stands for node. Because one of

1:17:57.840 --> 1:18:00.160
<v Speaker 4>the first ways that many cancer spread is via our

1:18:00.200 --> 1:18:04.639
<v Speaker 4>lymphatic systems, and our lymph system drains into lymph nodes

1:18:04.720 --> 1:18:07.280
<v Speaker 4>in specific patterns, and so we know, like your breast

1:18:07.280 --> 1:18:09.599
<v Speaker 4>tissue is going to drain towards a cluster of lymph

1:18:09.680 --> 1:18:12.519
<v Speaker 4>nodes in your armpit and other you know, your liver

1:18:12.600 --> 1:18:14.679
<v Speaker 4>is going to train to specific lymph nodes, et cetera.

1:18:15.280 --> 1:18:19.240
<v Speaker 4>And so by sampling the lymph nodes in the areas

1:18:19.520 --> 1:18:25.120
<v Speaker 4>where that original tumor is draining, we can figure out

1:18:25.240 --> 1:18:28.920
<v Speaker 4>how far the cancer has spread what we consider regionally

1:18:29.600 --> 1:18:30.320
<v Speaker 4>within the body.

1:18:30.439 --> 1:18:34.479
<v Speaker 1>So you would expect to find cancer cells within that

1:18:34.640 --> 1:18:35.320
<v Speaker 1>lymph node.

1:18:35.439 --> 1:18:38.160
<v Speaker 4>Potentially that could be that could be a first place

1:18:38.200 --> 1:18:39.080
<v Speaker 4>where they may spread.

1:18:39.800 --> 1:18:42.320
<v Speaker 1>And is there a possibility that it has spread but

1:18:42.520 --> 1:18:45.559
<v Speaker 1>not not? No evidence in the lymph node.

1:18:45.640 --> 1:18:49.439
<v Speaker 4>Absolutely, because the next step is m from atastases. Okay,

1:18:49.560 --> 1:18:52.520
<v Speaker 4>because the other way that cancer spread is via the bloodstream,

1:18:52.720 --> 1:18:56.800
<v Speaker 4>which means they can go anywhere. Very commonly, we see

1:18:56.800 --> 1:19:00.840
<v Speaker 4>places like the liver or the bones where cancers tend

1:19:00.880 --> 1:19:02.479
<v Speaker 4>to spread, and part of that is because we have

1:19:02.840 --> 1:19:05.640
<v Speaker 4>good blood flow to those areas, and also maybe that

1:19:05.680 --> 1:19:10.120
<v Speaker 4>those are just particularly conducive tissues to grow cancer cells.

1:19:10.160 --> 1:19:16.160
<v Speaker 4>Why who knows. But metastases can be literally anywhere. And

1:19:16.320 --> 1:19:18.400
<v Speaker 4>I said asterisk on the fact that cancers are going

1:19:18.439 --> 1:19:22.440
<v Speaker 4>to first spread locally. That's not always true. Some cancers

1:19:23.120 --> 1:19:27.000
<v Speaker 4>have these, especially what we call micrometastases, that might spread

1:19:27.280 --> 1:19:30.160
<v Speaker 4>very early in the course of disease, and we might

1:19:30.160 --> 1:19:32.160
<v Speaker 4>not even be able to pick those up if they're

1:19:32.240 --> 1:19:34.960
<v Speaker 4>very small. Because the ways that we tend to look

1:19:35.040 --> 1:19:38.680
<v Speaker 4>for metastatic growth is by doing imaging tests, so that

1:19:38.760 --> 1:19:41.439
<v Speaker 4>might be CT scans or MRIs or what are called

1:19:41.520 --> 1:19:45.080
<v Speaker 4>PET scans, and that is to look for evidence of

1:19:45.240 --> 1:19:48.200
<v Speaker 4>cancer in distant sites, far from that place where we

1:19:48.240 --> 1:19:52.240
<v Speaker 4>first identify a tumor. Okay, So by using all of

1:19:52.280 --> 1:19:56.599
<v Speaker 4>this information, we then can stage a cancer. And that's

1:19:56.600 --> 1:19:59.000
<v Speaker 4>where we think of like was it stage one? Stage two,

1:19:59.040 --> 1:20:02.160
<v Speaker 4>stage three, stage one, Like you, what stage was your cancer?

1:20:03.520 --> 1:20:07.720
<v Speaker 4>They don't all mean the same thing. And there's a

1:20:07.720 --> 1:20:09.519
<v Speaker 4>lot of nuance to this. So I'm not gonna like

1:20:09.560 --> 1:20:12.320
<v Speaker 4>get detailed into how we stage these cancers because some

1:20:12.400 --> 1:20:16.120
<v Speaker 4>get like to ab CD and things like that.

1:20:16.439 --> 1:20:18.920
<v Speaker 1>So many very yeah, so many variations.

1:20:18.360 --> 1:20:21.479
<v Speaker 4>And especially for some cancers that we have now done

1:20:21.520 --> 1:20:23.759
<v Speaker 4>a lot more research on and we understand much better,

1:20:24.120 --> 1:20:26.720
<v Speaker 4>breast cancer as one example, there might be a lot

1:20:26.800 --> 1:20:29.200
<v Speaker 4>more to staging than just this. There might be testing

1:20:29.240 --> 1:20:34.200
<v Speaker 4>for hormone receptors. There might be testing for particular antigens

1:20:34.240 --> 1:20:36.760
<v Speaker 4>that we see on the cancer that we happen to

1:20:36.800 --> 1:20:39.479
<v Speaker 4>have treatment for so we could then treat it with

1:20:39.640 --> 1:20:43.839
<v Speaker 4>specific medications. And so there's more to the staging process.

1:20:43.880 --> 1:20:46.000
<v Speaker 4>But this is the like broad strokes picture of it

1:20:47.080 --> 1:20:51.960
<v Speaker 4>that can give us a sense of I won't say prognosis,

1:20:52.040 --> 1:20:57.280
<v Speaker 4>because that's not quite true. Like it, how bad is

1:20:57.280 --> 1:21:00.360
<v Speaker 4>this going to be? Is not quite the point of it,

1:21:00.439 --> 1:21:03.000
<v Speaker 4>but it's part of it, right. It's being able to

1:21:03.120 --> 1:21:08.160
<v Speaker 4>group different types of cancers together, both for like clinical speak,

1:21:08.200 --> 1:21:10.120
<v Speaker 4>to be able to talk to somebody about their cancer

1:21:10.160 --> 1:21:13.280
<v Speaker 4>and have them understand this framework and also to be

1:21:13.280 --> 1:21:16.639
<v Speaker 4>able to do clinical trials so that people with similar

1:21:16.720 --> 1:21:20.280
<v Speaker 4>types of cancers with similar distributions in terms of nodes

1:21:20.280 --> 1:21:23.519
<v Speaker 4>and metastases and things, are going to be participating in

1:21:23.680 --> 1:21:27.320
<v Speaker 4>trials for different medications. And it also, I think creates

1:21:27.320 --> 1:21:31.519
<v Speaker 4>this language that allows us to say stage four means

1:21:31.520 --> 1:21:35.679
<v Speaker 4>that your cancer is metastatic, Stage zero means it has

1:21:35.720 --> 1:21:39.560
<v Speaker 4>not spread outside at all, and everything in between is

1:21:39.600 --> 1:21:40.920
<v Speaker 4>a lot more gray area.

1:21:41.479 --> 1:21:45.439
<v Speaker 1>Sort of like, Okay, how how long has this been

1:21:45.479 --> 1:21:48.599
<v Speaker 1>going on? How fast did we get here? And where

1:21:48.680 --> 1:21:49.599
<v Speaker 1>might this go from here?

1:21:50.040 --> 1:21:52.639
<v Speaker 4>Kind of except that every cancer moves differently in terms

1:21:52.640 --> 1:21:55.160
<v Speaker 4>of speed, so not so much on the how fast

1:21:55.160 --> 1:21:58.559
<v Speaker 4>did we get here necessarily, but like where are we not?

1:21:58.640 --> 1:21:59.599
<v Speaker 4>Where are we starting from?

1:22:00.040 --> 1:22:00.639
<v Speaker 1>Starting from?

1:22:00.880 --> 1:22:03.400
<v Speaker 4>And what does that mean for them? What the treatment

1:22:03.400 --> 1:22:04.479
<v Speaker 4>options are and things like that.

1:22:04.720 --> 1:22:07.960
<v Speaker 1>So okay, so let's say that you are you go

1:22:08.040 --> 1:22:11.320
<v Speaker 1>in because you suspect you have a suspicious growth, and

1:22:11.360 --> 1:22:13.480
<v Speaker 1>you're like, I want to get this checked out. Yeah,

1:22:13.520 --> 1:22:16.720
<v Speaker 1>what are the steps for staging? Like what does that

1:22:16.760 --> 1:22:18.000
<v Speaker 1>look like for someone?

1:22:18.120 --> 1:22:20.719
<v Speaker 4>I was hoping that you would ask me that question, Elsetair,

1:22:21.720 --> 1:22:23.479
<v Speaker 4>because it's like the question is like, how are we

1:22:23.520 --> 1:22:26.240
<v Speaker 4>diagnosing cancer, How are we doing this right? And it

1:22:26.280 --> 1:22:29.759
<v Speaker 4>can start with a really wide range of things, depending

1:22:29.800 --> 1:22:31.680
<v Speaker 4>on if you come in saying, you know, I have

1:22:31.760 --> 1:22:34.760
<v Speaker 4>a lump that I'm worried about, or if it's like

1:22:34.920 --> 1:22:39.240
<v Speaker 4>I've been losing weight and I'm not I'm nauseous, or

1:22:39.320 --> 1:22:41.920
<v Speaker 4>if it's I'm fatigued, and so like, the how you

1:22:41.960 --> 1:22:46.320
<v Speaker 4>get exactly to that initial diagnosis can really really vary

1:22:46.760 --> 1:22:48.920
<v Speaker 4>depending on the type of cancer that we're talking about.

1:22:49.000 --> 1:22:51.240
<v Speaker 4>A cervical cancer we might pick up on a pap smear,

1:22:51.560 --> 1:22:53.640
<v Speaker 4>a breast cancer we might pick up on a mammogram.

1:22:53.920 --> 1:22:56.120
<v Speaker 4>Something like a blood cancer. You might have to have

1:22:56.160 --> 1:22:58.960
<v Speaker 4>blood work done and it just be abnormal for someone

1:22:58.960 --> 1:23:01.559
<v Speaker 4>to be able to recognize that. So there's a huge

1:23:01.640 --> 1:23:03.720
<v Speaker 4>range of how we get to that initial one. But

1:23:03.760 --> 1:23:08.080
<v Speaker 4>then the next step is actually a tissue diagnosis, which

1:23:08.120 --> 1:23:10.280
<v Speaker 4>means getting a biopsy to be able to do all

1:23:10.280 --> 1:23:12.600
<v Speaker 4>those things we said, where did this come from, what

1:23:12.720 --> 1:23:16.160
<v Speaker 4>kind of cells are are they, et cetera. And then

1:23:16.200 --> 1:23:19.520
<v Speaker 4>the staging process is going to be usually a relatively

1:23:19.560 --> 1:23:23.519
<v Speaker 4>long process of many, many appointments, but it might include

1:23:23.560 --> 1:23:28.400
<v Speaker 4>in addition to that biopsy, it might include node biopsies, so,

1:23:28.479 --> 1:23:31.120
<v Speaker 4>especially for something like breast cancer, you might get node

1:23:31.160 --> 1:23:33.519
<v Speaker 4>biopsies at the same time that you get an initial

1:23:33.560 --> 1:23:36.680
<v Speaker 4>biopsy because we know those nodes very well, we know

1:23:36.720 --> 1:23:39.240
<v Speaker 4>which ones to sample for in what quadrants, et cetera.

1:23:40.400 --> 1:23:42.160
<v Speaker 4>For others, it might not. There might not be a

1:23:42.160 --> 1:23:45.360
<v Speaker 4>nodal biopsy until there's maybe an exploratory surgery or some

1:23:45.520 --> 1:23:47.720
<v Speaker 4>kind of surgery to remove the cancer, and then you

1:23:47.760 --> 1:23:49.679
<v Speaker 4>would sample lymph nodes at that same time.

1:23:49.800 --> 1:23:52.400
<v Speaker 1>What is it tell me walk me through a node biopsy?

1:23:52.680 --> 1:23:57.040
<v Speaker 4>Oh, I mean, I'm not a surgeon or an interventional radiologist,

1:23:57.080 --> 1:23:58.400
<v Speaker 4>but you are an MD.

1:23:59.360 --> 1:24:01.960
<v Speaker 1>So just hoping for some broad strokes subscription.

1:24:02.200 --> 1:24:05.200
<v Speaker 4>It depends on It depends on the type of cancer

1:24:05.240 --> 1:24:07.479
<v Speaker 4>and things. For breast cancer, you could do it without

1:24:07.560 --> 1:24:10.320
<v Speaker 4>necessarily needing to do like an open surgery or anything.

1:24:10.479 --> 1:24:12.000
<v Speaker 4>So you might be able to do a lymph node

1:24:12.040 --> 1:24:17.360
<v Speaker 4>biopsy with just like an in interventional radiology type of procedure.

1:24:17.880 --> 1:24:19.280
<v Speaker 4>The same thing might be true for a lot of

1:24:19.280 --> 1:24:22.519
<v Speaker 4>biopsies of things like maybe your liver or even lungs.

1:24:22.560 --> 1:24:25.320
<v Speaker 4>You could do with like a broncoscopy. You could do

1:24:26.000 --> 1:24:28.040
<v Speaker 4>a lot of different biopsies in multiple different ways of

1:24:28.040 --> 1:24:32.040
<v Speaker 4>both lymph noodes and the tumor itself, whereas for others

1:24:32.960 --> 1:24:35.760
<v Speaker 4>you might not, like in your guts, it's very hard

1:24:35.800 --> 1:24:37.800
<v Speaker 4>to sample some of those lymph nodes, and so you

1:24:37.880 --> 1:24:39.799
<v Speaker 4>might not be able to do a lymph noode biopsy

1:24:39.880 --> 1:24:42.040
<v Speaker 4>until you're doing a surgery, and then you might take

1:24:42.080 --> 1:24:46.240
<v Speaker 4>the whole entire lymph node rather than just us samample. Okay,

1:24:46.280 --> 1:24:50.439
<v Speaker 4>And there's obviously pros and cons to doing both and right, right,

1:24:50.600 --> 1:24:53.120
<v Speaker 4>but hopefully that was a good answer.

1:24:53.360 --> 1:24:55.320
<v Speaker 1>It was great, Thank you so much.

1:24:56.720 --> 1:24:58.640
<v Speaker 4>And then and then after we have all of that,

1:24:58.720 --> 1:25:00.960
<v Speaker 4>then you're also going to get images tests as well too,

1:25:01.120 --> 1:25:04.479
<v Speaker 4>and that's to look for distant metastases. And you know,

1:25:04.560 --> 1:25:07.240
<v Speaker 4>depending on the types of cancer, there could be a lot.

1:25:07.240 --> 1:25:10.920
<v Speaker 1>How well does imaging what what is the imaging and

1:25:10.960 --> 1:25:14.000
<v Speaker 1>then like are there cancers that are missed by imaging

1:25:14.240 --> 1:25:15.120
<v Speaker 1>or yeah.

1:25:15.080 --> 1:25:19.240
<v Speaker 4>Yes, yes, definitely okay, especially I mean, I would say

1:25:19.320 --> 1:25:22.880
<v Speaker 4>especially micrometastases, Like we're not going to be able to

1:25:22.880 --> 1:25:26.280
<v Speaker 4>pick up a handful of cells somewhere, right, which is

1:25:26.280 --> 1:25:29.200
<v Speaker 4>why a lot of times chemotherapy is still recommended. Even

1:25:29.280 --> 1:25:31.519
<v Speaker 4>if you think we had a surgery, we got good

1:25:31.560 --> 1:25:34.400
<v Speaker 4>margins we didn't see any metastases. There still might be

1:25:34.400 --> 1:25:36.720
<v Speaker 4>a recommendation for chemotherapy because we just don't know if

1:25:36.720 --> 1:25:42.639
<v Speaker 4>there's other cells hanging out locally or more broadly. But yeah,

1:25:42.800 --> 1:25:46.040
<v Speaker 4>MRI is sometimes used. CT scans are sometimes used, and

1:25:46.080 --> 1:25:49.280
<v Speaker 4>then PET scans, which are this like weird and fancy

1:25:49.320 --> 1:25:52.520
<v Speaker 4>way to look at metabolism.

1:25:52.560 --> 1:25:54.559
<v Speaker 1>Basically, it's really cool. It is really cool.

1:25:55.200 --> 1:25:57.679
<v Speaker 4>There's still like a mystery for me, but you basically

1:25:57.680 --> 1:26:00.439
<v Speaker 4>are looking at like glucose uptake and metabolism so that

1:26:00.479 --> 1:26:02.960
<v Speaker 4>you can see if cells are looking like they're growing

1:26:02.960 --> 1:26:03.920
<v Speaker 4>more than they ought to.

1:26:04.160 --> 1:26:06.080
<v Speaker 1>And you can do fancy scans you can do if

1:26:06.080 --> 1:26:09.799
<v Speaker 1>you can find specific targeted cell cancer cells exactly. But okay, okay,

1:26:10.120 --> 1:26:12.960
<v Speaker 1>I just didn't know how well imaging captures.

1:26:13.320 --> 1:26:15.400
<v Speaker 4>Yeah, it all just depends like it just depends on

1:26:15.439 --> 1:26:18.880
<v Speaker 4>the size. And that's why most people with cancer are

1:26:18.880 --> 1:26:21.240
<v Speaker 4>going to have many scans. It's not going to be

1:26:21.320 --> 1:26:22.880
<v Speaker 4>just the one. It's going to be that first one

1:26:22.920 --> 1:26:24.800
<v Speaker 4>for staging, and then they're going to have scans to

1:26:24.840 --> 1:26:27.280
<v Speaker 4>look for evidence of recurrence or new metastases that we

1:26:27.320 --> 1:26:31.559
<v Speaker 4>didn't know about. Because things can change, you know, very rapidly, right,

1:26:32.800 --> 1:26:35.919
<v Speaker 4>when it comes to how cancer is affecting our body's

1:26:35.960 --> 1:26:40.439
<v Speaker 4>big picture, most cancer deaths are due to metastasis, meaning

1:26:40.520 --> 1:26:42.639
<v Speaker 4>because of the way that this cancer has spread through

1:26:42.640 --> 1:26:46.320
<v Speaker 4>our bodies, and like what is the exact mechanism of that.

1:26:46.720 --> 1:26:50.439
<v Speaker 4>Who knows, Like it can really really depend. Like it

1:26:50.479 --> 1:26:53.200
<v Speaker 4>could be that you have metastases to your liver, and

1:26:53.240 --> 1:26:55.559
<v Speaker 4>so now your liver is failing because it can't function

1:26:55.600 --> 1:26:58.240
<v Speaker 4>anymore because it's full of cancer. It could be that

1:26:58.280 --> 1:27:01.759
<v Speaker 4>you have brain metastases again your brain or your kidney

1:27:01.920 --> 1:27:05.960
<v Speaker 4>or whatever it is. Sometimes also we can see that,

1:27:06.120 --> 1:27:09.519
<v Speaker 4>like if tumors grow large or very numerous, they might

1:27:09.600 --> 1:27:14.360
<v Speaker 4>start to lice themselves or sometimes that can happen as

1:27:14.360 --> 1:27:17.439
<v Speaker 4>a result of treatment, and that can be very very

1:27:17.479 --> 1:27:20.000
<v Speaker 4>dangerous because you're basically releasing a bunch of things that

1:27:20.040 --> 1:27:21.960
<v Speaker 4>are supposed to be inside cells, and that trigger is

1:27:22.000 --> 1:27:28.120
<v Speaker 4>a really strong immune response, Yeah, exactly. There's also though,

1:27:28.520 --> 1:27:33.720
<v Speaker 4>cancer requires a lot from our bodies in terms of

1:27:33.760 --> 1:27:38.080
<v Speaker 4>our metabolic load, and so it ends up just weakening

1:27:38.360 --> 1:27:41.479
<v Speaker 4>our bodies until they really can't function anymore. And so

1:27:41.640 --> 1:27:46.040
<v Speaker 4>this can result in something called cancer associated cachexia, which

1:27:46.080 --> 1:27:50.120
<v Speaker 4>is really really awful and it's just this depletion of

1:27:50.520 --> 1:27:56.559
<v Speaker 4>skeletal muscle mass, especially skeletal muscle mass, that cannot be

1:27:56.800 --> 1:28:02.000
<v Speaker 4>entirely reversed no matter how much nutritional support you give someone.

1:28:02.200 --> 1:28:04.840
<v Speaker 4>And it's ever yeah, it's it's I mean, it's not

1:28:04.880 --> 1:28:08.160
<v Speaker 4>like no one can recover from this, but you until

1:28:08.200 --> 1:28:10.920
<v Speaker 4>you get that cancer under control, right right, right, Okay,

1:28:11.320 --> 1:28:14.120
<v Speaker 4>the cancer itself is doing this, and so you can't

1:28:14.720 --> 1:28:15.960
<v Speaker 4>completely reverse it.

1:28:15.960 --> 1:28:17.600
<v Speaker 1>It's just diverting all the resources.

1:28:17.640 --> 1:28:22.120
<v Speaker 4>Exactly. It's exactly that. And it's a very multifactorial thing

1:28:22.160 --> 1:28:24.519
<v Speaker 4>because a lot of times we do see like people

1:28:24.600 --> 1:28:27.400
<v Speaker 4>having either food aversions or nausea, whether it's from the

1:28:27.439 --> 1:28:31.519
<v Speaker 4>medications or from the cancer itself, or if you're talking

1:28:31.520 --> 1:28:34.040
<v Speaker 4>about like a head of net cancer or an upper

1:28:34.080 --> 1:28:37.200
<v Speaker 4>GI cancer, you might not be able to eat physically,

1:28:37.520 --> 1:28:39.879
<v Speaker 4>and so then it's very difficult to get nutrients answers

1:28:39.960 --> 1:28:43.080
<v Speaker 4>it comes. There's a lot that goes into a kaxia

1:28:43.080 --> 1:28:45.800
<v Speaker 4>associated with cancer, but that is a really big cause

1:28:45.800 --> 1:28:48.280
<v Speaker 4>of death. One estimate that I saw was that cancer

1:28:48.320 --> 1:28:51.799
<v Speaker 4>associated kakexia accounts for nearly half of all the deaths

1:28:51.800 --> 1:28:57.040
<v Speaker 4>associated with cancer worldwide, which is which is really huge.

1:28:57.120 --> 1:28:59.960
<v Speaker 4>And then there's also the fact that cancer dysregulates our

1:29:00.000 --> 1:29:02.960
<v Speaker 4>immune system in a very profound way, especially when it

1:29:03.000 --> 1:29:06.880
<v Speaker 4>gets to be metastatic, and so it can end up

1:29:06.960 --> 1:29:10.280
<v Speaker 4>causing things like blood clots and thrumba embolism or blood

1:29:10.280 --> 1:29:12.400
<v Speaker 4>clots are a really big cause of death for people

1:29:12.400 --> 1:29:14.600
<v Speaker 4>with cancer as well. So there's just a lot of

1:29:14.640 --> 1:29:18.800
<v Speaker 4>ways that cancer dysregulates our body and then can end

1:29:18.880 --> 1:29:22.599
<v Speaker 4>up leading to death, like in a lot of different ways.

1:29:23.080 --> 1:29:27.000
<v Speaker 1>Why are I know, I know that we're not going

1:29:27.040 --> 1:29:31.519
<v Speaker 1>to talk about specific cancers, but why is there such

1:29:31.640 --> 1:29:33.880
<v Speaker 1>very you know, looking at different organ system or like

1:29:34.040 --> 1:29:36.880
<v Speaker 1>point of origin, organ of origin, Why is there such

1:29:36.880 --> 1:29:40.800
<v Speaker 1>a difference tends to be such a difference in you know,

1:29:40.880 --> 1:29:49.000
<v Speaker 1>metastasis and fatal you know, fatality and treatment receptibility. What

1:29:49.120 --> 1:29:51.720
<v Speaker 1>is it being able to be treated? I can't think

1:29:51.720 --> 1:29:52.120
<v Speaker 1>of the word.

1:29:52.280 --> 1:29:54.920
<v Speaker 4>It's hard, Aaron, because it's so many different things. I

1:29:54.920 --> 1:29:58.880
<v Speaker 4>think that play into that. Some of it is our

1:29:58.920 --> 1:30:02.479
<v Speaker 4>ability to screen for things, and so we are able

1:30:02.520 --> 1:30:05.040
<v Speaker 4>to catch some cancers a lot earlier than we can

1:30:05.080 --> 1:30:08.080
<v Speaker 4>catch other cancers, and therefore we can treat them more

1:30:08.120 --> 1:30:10.960
<v Speaker 4>effectively with the same treatments that we would use for

1:30:11.040 --> 1:30:13.760
<v Speaker 4>another cancer. Pancreatic cancer is a really good example of that,

1:30:13.920 --> 1:30:17.439
<v Speaker 4>like and ovarian cancer is another one where a lot

1:30:17.479 --> 1:30:21.720
<v Speaker 4>of times these are completely asymptomatic until it's really bad, bad,

1:30:21.800 --> 1:30:25.600
<v Speaker 4>until it's already spread at least regionally, if not widespread.

1:30:26.800 --> 1:30:29.400
<v Speaker 4>And so that's part of it, whereas breast cancer, prostate

1:30:29.439 --> 1:30:32.000
<v Speaker 4>cancer like things that we can screen for, we can

1:30:32.040 --> 1:30:35.759
<v Speaker 4>potentially catch earlier. And some of it is just cancer

1:30:35.800 --> 1:30:37.640
<v Speaker 4>specific that I don't know the answer to. I'd have

1:30:37.640 --> 1:30:41.040
<v Speaker 4>to dig on each specific cancer of like why pancreatic

1:30:41.080 --> 1:30:44.360
<v Speaker 4>cancer is so so And some of it too, is

1:30:44.360 --> 1:30:47.960
<v Speaker 4>that we research cancers that are more common, and there's

1:30:47.960 --> 1:30:51.280
<v Speaker 4>more funding for cancers that are more common, which is logical,

1:30:51.479 --> 1:30:53.400
<v Speaker 4>which means that cancers that are more rare are going

1:30:53.439 --> 1:30:55.240
<v Speaker 4>to have a lot less treatment options. They're going to

1:30:55.280 --> 1:30:57.200
<v Speaker 4>be harder for us to detect, harder for us to

1:30:57.240 --> 1:31:00.640
<v Speaker 4>even think about checking for, and then harder for us

1:31:00.640 --> 1:31:02.599
<v Speaker 4>to treat because we don't have as many treatment options

1:31:02.640 --> 1:31:04.519
<v Speaker 4>available for those kinds of cancers. And that's a really

1:31:04.560 --> 1:31:05.440
<v Speaker 4>huge issue.

1:31:05.200 --> 1:31:07.720
<v Speaker 1>Right And then if they're if they're rarer, then it's

1:31:07.720 --> 1:31:11.280
<v Speaker 1>harder to have clinical trials that then you know, show

1:31:11.400 --> 1:31:13.160
<v Speaker 1>the performance of this treatment versus another.

1:31:13.960 --> 1:31:16.000
<v Speaker 4>So you're relying on a lot less data to guide

1:31:16.040 --> 1:31:19.680
<v Speaker 4>your therapy to begin with. So there's there's so much that.

1:31:19.640 --> 1:31:20.479
<v Speaker 1>So many factors.

1:31:20.520 --> 1:31:26.480
<v Speaker 4>Yeah, but obviously cancer can and does end up affecting

1:31:26.800 --> 1:31:30.840
<v Speaker 4>our entire body system. But I haven't even told you

1:31:30.920 --> 1:31:33.639
<v Speaker 4>at all. How does this actually apply?

1:31:34.040 --> 1:31:34.479
<v Speaker 1>It happen?

1:31:34.760 --> 1:31:37.320
<v Speaker 4>How does a cell in our body just up and

1:31:37.360 --> 1:31:40.439
<v Speaker 4>decide to go rogue? Is that really what happens? Why

1:31:40.680 --> 1:31:43.719
<v Speaker 4>is tobacco, smoke and genetics? Like, how do all these

1:31:44.160 --> 1:31:48.519
<v Speaker 4>virus environment genetics play a role. That is where we'll

1:31:48.520 --> 1:31:51.680
<v Speaker 4>pick up next week here, Cliffanger, Cliffhangers, we love them,

1:31:51.760 --> 1:31:56.200
<v Speaker 4>we do, we do. Gosh, I know it was a lot.

1:31:56.160 --> 1:31:59.560
<v Speaker 1>I feel like. I mean, yeah, we've we've covered a

1:31:59.560 --> 1:32:00.800
<v Speaker 1>lot of grond already.

1:32:00.479 --> 1:32:01.919
<v Speaker 4>And I have so many more questions.

1:32:02.000 --> 1:32:04.559
<v Speaker 1>I know. I feel like we've also barely scratched the surface.

1:32:04.640 --> 1:32:05.559
<v Speaker 4>Yeah, that's true.

1:32:05.720 --> 1:32:08.200
<v Speaker 1>This is an iceberg of a top.

1:32:08.400 --> 1:32:11.559
<v Speaker 4>And if you want more below the surface, boy do

1:32:11.640 --> 1:32:13.960
<v Speaker 4>we have very well?

1:32:14.040 --> 1:32:17.120
<v Speaker 1>Then we planned that, we did not plan that. We

1:32:17.160 --> 1:32:21.120
<v Speaker 1>have a lot of sources. I have so many, And

1:32:21.120 --> 1:32:23.160
<v Speaker 1>then I just wrote a few here to shout.

1:32:23.000 --> 1:32:25.400
<v Speaker 4>Out so long y'all, like please go to our website

1:32:25.400 --> 1:32:26.840
<v Speaker 4>this podcast will kay you dot Com, click on the

1:32:26.880 --> 1:32:28.040
<v Speaker 4>episode's tab and it.

1:32:28.000 --> 1:32:31.439
<v Speaker 1>Is such a long list it was really hard to stop. Yeah,

1:32:31.479 --> 1:32:34.400
<v Speaker 1>and there are some really great sources. Okay, So for

1:32:34.560 --> 1:32:37.599
<v Speaker 1>this episode, A few of the sources that I found

1:32:37.600 --> 1:32:40.920
<v Speaker 1>the most helpful are The Emperor of All Maladies, A

1:32:40.960 --> 1:32:44.559
<v Speaker 1>biography of cancer. It's classic, it's Pulser Prize winning. It

1:32:44.640 --> 1:32:49.280
<v Speaker 1>is yes, by sid Arthur Mukerjee, published in twenty ten.

1:32:49.600 --> 1:32:53.160
<v Speaker 1>Then there's another book called Terratologies, A Cultural Study of

1:32:53.160 --> 1:32:57.240
<v Speaker 1>Cancer by Jackie Stacy, which I think this is twenty thirteen,

1:32:57.240 --> 1:32:59.599
<v Speaker 1>but I think it came out earlier than that. I'm

1:32:59.600 --> 1:33:02.960
<v Speaker 1>not sure. That was a really interesting perspective on our

1:33:03.200 --> 1:33:07.200
<v Speaker 1>perception of cancer today and how that's shifted. Then there's

1:33:07.240 --> 1:33:11.559
<v Speaker 1>a series by had You from twenty eleven going all

1:33:11.560 --> 1:33:14.320
<v Speaker 1>the way through like twenty sixteen or something like that,

1:33:14.680 --> 1:33:17.800
<v Speaker 1>seven part series called A Note from History, Landmarks and

1:33:17.920 --> 1:33:20.959
<v Speaker 1>History of Cancer one through seven. Hugely informative.

1:33:21.000 --> 1:33:22.040
<v Speaker 4>Okay, I love yeah.

1:33:22.200 --> 1:33:26.080
<v Speaker 1>And then also more about sort of the historical perception

1:33:26.160 --> 1:33:29.439
<v Speaker 1>of cancer is a dread disease. Cancer in modern American

1:33:29.479 --> 1:33:32.639
<v Speaker 1>culture by James Patterson nineteen eighty eight.

1:33:32.920 --> 1:33:34.719
<v Speaker 4>Not the same James Patterson that my dad reads.

1:33:34.880 --> 1:33:37.680
<v Speaker 1>I don't believe, so I'd have to double check on that.

1:33:39.560 --> 1:33:42.439
<v Speaker 4>I have a number of papers as well too. I

1:33:42.479 --> 1:33:46.600
<v Speaker 4>also just want to shout out the National Cancer Institute

1:33:47.040 --> 1:33:49.559
<v Speaker 4>has like a cancer classification. They have these like training

1:33:49.560 --> 1:33:51.400
<v Speaker 4>modules that anyone can access.

1:33:51.200 --> 1:33:53.040
<v Speaker 1>There's a wealth of information there.

1:33:53.080 --> 1:33:55.360
<v Speaker 4>Yeah, it's really great. So I have a link to that.

1:33:55.400 --> 1:33:57.240
<v Speaker 4>That paper that I mentioned that was like updating the

1:33:57.240 --> 1:34:00.839
<v Speaker 4>definitions of cancer was by Brown at All from twenty

1:34:01.200 --> 1:34:04.519
<v Speaker 4>twenty three, called Updating the Definition of Cancer. I thought

1:34:04.520 --> 1:34:07.600
<v Speaker 4>that was just an interesting read. And then if you

1:34:07.600 --> 1:34:09.920
<v Speaker 4>want more about the staging of cancer, there's a paper

1:34:09.960 --> 1:34:11.640
<v Speaker 4>it's kind of old from two thousand and eight by

1:34:11.680 --> 1:34:14.240
<v Speaker 4>Green and Sobin called the Staging of Cancer a retrospective

1:34:14.280 --> 1:34:15.720
<v Speaker 4>and perspective appraisate.

1:34:15.360 --> 1:34:17.280
<v Speaker 1>Early twenty first century. I don't know.

1:34:19.080 --> 1:34:21.479
<v Speaker 4>And then there's so much more. Go to our website,

1:34:21.560 --> 1:34:23.759
<v Speaker 4>check it out, you can see it at all. I'm done.
