WEBVTT - Ep 205 Cancer Part 4: Where do things stand today?

0:00:00.080 --> 0:00:03.640
<v Speaker 1>Throughout this series, we'll be discussing many aspects of cancer

0:00:03.720 --> 0:00:07.160
<v Speaker 1>diagnosis and treatment, and we will be sharing several personal

0:00:07.200 --> 0:00:11.280
<v Speaker 1>stories related to cancer. Some listeners might find this content upsetting.

0:00:11.680 --> 0:00:12.960
<v Speaker 1>Please listen with discretion.

0:00:14.960 --> 0:00:17.200
<v Speaker 2>My name is Christina and I'm a healthy, cancer free,

0:00:17.239 --> 0:00:19.119
<v Speaker 2>thirty year old woman who was about to undergo a

0:00:19.160 --> 0:00:22.400
<v Speaker 2>double mistact tomy. Let me tell you why. My aunt

0:00:22.400 --> 0:00:25.040
<v Speaker 2>Helen was diagnosed with breast cancer at age thirty four

0:00:25.120 --> 0:00:27.840
<v Speaker 2>and ultimately passed away ten years later when I was thirteen.

0:00:28.480 --> 0:00:30.600
<v Speaker 2>Just a few years later, still relinking the loss of

0:00:30.600 --> 0:00:33.879
<v Speaker 2>our beloved Helen, another aunt was diagnosed with ovarian cancer.

0:00:34.400 --> 0:00:36.159
<v Speaker 2>My whole life, I had looked at my aunts and

0:00:36.200 --> 0:00:39.120
<v Speaker 2>saw myself fall blue eyes and big foreheads and curly hair.

0:00:39.640 --> 0:00:41.600
<v Speaker 2>If their fate was cancer, it was bound to be

0:00:41.640 --> 0:00:45.519
<v Speaker 2>mine too. And it wasn't just my aunt's. Six other relatives,

0:00:45.520 --> 0:00:47.760
<v Speaker 2>from great aunts to distant cousins had been diagnosed with

0:00:47.800 --> 0:00:50.479
<v Speaker 2>either breast or ovarian cancer. It was high time for

0:00:50.560 --> 0:00:52.840
<v Speaker 2>genetic testing, and we discovered that my aunt and father

0:00:52.920 --> 0:00:56.480
<v Speaker 2>carry the Brocketuo mutation. This mutation is associated with a

0:00:56.520 --> 0:00:59.080
<v Speaker 2>forty to eighty five percent lifetime risk for breast cancer

0:00:59.320 --> 0:01:01.840
<v Speaker 2>and fifteen to forty percent risk for a varian cancer,

0:01:02.120 --> 0:01:05.640
<v Speaker 2>along with increased risks for other cancers including prostate, pancreatic,

0:01:05.680 --> 0:01:09.720
<v Speaker 2>and melanomas. As a teenager, I wanted to be tested immediately.

0:01:10.160 --> 0:01:12.479
<v Speaker 2>This was around when the Affordable Care Act was being passed,

0:01:12.480 --> 0:01:15.040
<v Speaker 2>and my doctors recommended that I wait until protections for

0:01:15.080 --> 0:01:18.559
<v Speaker 2>pre existing conditions were fully in effect before diagnosing myself

0:01:18.600 --> 0:01:22.000
<v Speaker 2>with one. Finally, at nineteen, I received confirmation of what

0:01:22.080 --> 0:01:24.520
<v Speaker 2>I had felt for years. Just like my aunts, I

0:01:24.560 --> 0:01:27.600
<v Speaker 2>was positive for rokutwo. I heard constantly at the time

0:01:27.600 --> 0:01:29.920
<v Speaker 2>that nineteen was too young to test, years before any

0:01:29.959 --> 0:01:33.080
<v Speaker 2>screenings would be recommended, but I wanted those years to

0:01:33.120 --> 0:01:35.600
<v Speaker 2>sit with my diagnosis and process it as slowly as

0:01:35.600 --> 0:01:38.280
<v Speaker 2>I wanted to. I'm so grateful for the protections that

0:01:38.360 --> 0:01:41.440
<v Speaker 2>allowed me to do so. My cancer screenings began at

0:01:41.440 --> 0:01:44.360
<v Speaker 2>twenty four, and for six years, I dutifully scheduled breast

0:01:44.360 --> 0:01:47.400
<v Speaker 2>exam skin checks, and an annual date was a clunking,

0:01:47.520 --> 0:01:51.680
<v Speaker 2>thumping MRI. I'm treated by an excellent hereditary cancer clinic,

0:01:51.720 --> 0:01:54.120
<v Speaker 2>and my team is optimistic that any breast cancer would

0:01:54.120 --> 0:01:56.680
<v Speaker 2>be caught early and be survivable. But that's not good

0:01:56.760 --> 0:01:59.320
<v Speaker 2>enough for me. I don't want to survive breast cancer.

0:02:00.040 --> 0:02:03.800
<v Speaker 2>They never have it at all. Hereditary cancer causes incalculable

0:02:03.800 --> 0:02:06.360
<v Speaker 2>loss in trauma to the families that it tears. Through

0:02:06.800 --> 0:02:10.000
<v Speaker 2>both modern genetic testing, younger generations can use that trauma

0:02:10.040 --> 0:02:13.080
<v Speaker 2>to ford a different path forward. My journey has always

0:02:13.120 --> 0:02:15.919
<v Speaker 2>been mapped onto my aunt Helens. The age I started

0:02:15.919 --> 0:02:18.480
<v Speaker 2>cancer screenings and planning for my mistectomy is all based

0:02:18.480 --> 0:02:20.880
<v Speaker 2>on her timeline and the hopes that mine can be different.

0:02:21.520 --> 0:02:24.160
<v Speaker 2>My double mistectomy will reduce my lifetime risk of cancer

0:02:24.200 --> 0:02:27.360
<v Speaker 2>by ninety to ninety five percent. It's not one hundred percent,

0:02:27.440 --> 0:02:29.360
<v Speaker 2>but it's nothing less than a gift.

0:02:30.160 --> 0:02:30.520
<v Speaker 3>Hi.

0:02:30.680 --> 0:02:34.280
<v Speaker 4>I'm clear from South Africa and I'm undergoing treatment for

0:02:34.480 --> 0:02:38.079
<v Speaker 4>cholorectal cancer. I knew something was wrong for at least

0:02:38.120 --> 0:02:40.799
<v Speaker 4>a year before I did anything about it. As a

0:02:40.840 --> 0:02:43.400
<v Speaker 4>friend said, we're more scared of the treatment than the disease.

0:02:44.120 --> 0:02:46.760
<v Speaker 4>When I finally went for colonoscopy, I'm pretty sure I

0:02:46.840 --> 0:02:49.560
<v Speaker 4>knew I had cancer. It's always been my biggest fear,

0:02:50.080 --> 0:02:52.080
<v Speaker 4>But in a way, it's freeing knowing that the waste

0:02:52.080 --> 0:02:55.200
<v Speaker 4>has happened after barely interacting with a medical system. For

0:02:55.200 --> 0:02:57.560
<v Speaker 4>forty one years of my life. I have now had

0:02:57.600 --> 0:03:01.000
<v Speaker 4>two major surgeries, spent weeks in US. You have an

0:03:01.000 --> 0:03:05.920
<v Speaker 4>iliostomy and am undergoing chemo. Finding chemo very frustrating because

0:03:05.960 --> 0:03:08.720
<v Speaker 4>no one knows how each person will react, so hard

0:03:08.760 --> 0:03:11.400
<v Speaker 4>to tell if it will get worse or better. I'm

0:03:11.400 --> 0:03:14.000
<v Speaker 4>trying to stay very positive and interested in the biology

0:03:14.040 --> 0:03:16.000
<v Speaker 4>of it all, and also trying to be a good

0:03:16.000 --> 0:03:19.160
<v Speaker 4>example and educate my students. I teach high school science

0:03:19.160 --> 0:03:22.360
<v Speaker 4>and bio. I really wish people were more open about

0:03:22.360 --> 0:03:25.360
<v Speaker 4>gross body processes because I'm sure if we talked more

0:03:25.360 --> 0:03:29.040
<v Speaker 4>about poo, more people would be diagnosed earlier. As it is,

0:03:29.120 --> 0:03:31.240
<v Speaker 4>I'm telling everyone to go for krodnoscopies.

0:04:17.360 --> 0:04:20.520
<v Speaker 1>Thank you all again so so much for sharing your

0:04:20.560 --> 0:04:24.120
<v Speaker 1>stories with us. We are truly touched and cannot believe

0:04:24.160 --> 0:04:27.040
<v Speaker 1>how many people wrote in We're willing to be vulnerable

0:04:27.640 --> 0:04:32.200
<v Speaker 1>and share such an intimate part of their lives with us,

0:04:32.640 --> 0:04:35.400
<v Speaker 1>because it really adds more than we can possibly say

0:04:35.400 --> 0:04:37.840
<v Speaker 1>to the series, So thank you, it really does. Thank you.

0:04:38.400 --> 0:04:40.479
<v Speaker 5>We have a lot more stories that will also be

0:04:40.520 --> 0:04:43.480
<v Speaker 5>sharing that we have shared throughout this series and throughout

0:04:43.480 --> 0:04:46.599
<v Speaker 5>this episode. We really wish that we could have included

0:04:46.600 --> 0:04:50.200
<v Speaker 5>every story. Thank you so much to everyone who wrote

0:04:50.240 --> 0:04:52.840
<v Speaker 5>in and who recorded your stories and who shared them

0:04:52.839 --> 0:04:55.360
<v Speaker 5>with us. We really just can't say thank.

0:04:55.240 --> 0:04:57.040
<v Speaker 1>You enough, even though we've tried.

0:04:57.120 --> 0:04:57.559
<v Speaker 2>We tried.

0:04:58.960 --> 0:05:01.840
<v Speaker 3>Hi, I'm Aaron, and I'm Aaron aman Updyke and.

0:05:01.960 --> 0:05:03.880
<v Speaker 1>This is this podcast will kill you.

0:05:04.000 --> 0:05:07.719
<v Speaker 5>Welcome to episode four and final for and final of

0:05:07.800 --> 0:05:09.320
<v Speaker 5>our series on cancer.

0:05:09.640 --> 0:05:12.040
<v Speaker 3>It's been a journey.

0:05:12.480 --> 0:05:17.440
<v Speaker 1>Yeah, that's that's the word. Yeah. Yeah, We've covered a

0:05:17.440 --> 0:05:19.919
<v Speaker 1>lot of ground so far in this series. If this

0:05:20.080 --> 0:05:23.800
<v Speaker 1>is your first time tuning into the Cancer series, you

0:05:24.720 --> 0:05:25.920
<v Speaker 1>can listen to these out of order.

0:05:26.000 --> 0:05:28.000
<v Speaker 5>Honestly, this would not be a bad place to start.

0:05:28.040 --> 0:05:31.080
<v Speaker 5>We could have started here, we could have, but we're

0:05:31.160 --> 0:05:31.920
<v Speaker 5>ending here instead.

0:05:32.080 --> 0:05:34.000
<v Speaker 1>The point is that these are all pieces of a

0:05:34.040 --> 0:05:36.599
<v Speaker 1>big puzzle, and there are still pieces that we haven't

0:05:36.640 --> 0:05:39.200
<v Speaker 1>filled in yet, pieces that remain to be filled in

0:05:39.240 --> 0:05:41.599
<v Speaker 1>by science and medicine. But we can tell you what

0:05:41.640 --> 0:05:45.160
<v Speaker 1>we've covered so far. So the first episode we talked

0:05:45.160 --> 0:05:48.680
<v Speaker 1>about what cancer is, both conceptually and clinically, kind of

0:05:48.720 --> 0:05:52.640
<v Speaker 1>the definitions of cancer. The second episode we talked about

0:05:52.720 --> 0:05:56.039
<v Speaker 1>the evolution of cancer and cellular aspects of cancer, So like,

0:05:56.080 --> 0:05:59.440
<v Speaker 1>what's actually happening within that cancer cell to make it cancerous.

0:06:00.000 --> 0:06:03.360
<v Speaker 1>Third episode, last episode all about treatment, history of treatment,

0:06:03.560 --> 0:06:08.120
<v Speaker 1>existing treatments today, possible treatments in the future. And today

0:06:08.880 --> 0:06:11.880
<v Speaker 1>we're talking about kind of the big picture of like

0:06:12.480 --> 0:06:15.840
<v Speaker 1>what the status of cancer is around the world today

0:06:16.640 --> 0:06:18.919
<v Speaker 1>and ways that we might be able to see that

0:06:19.000 --> 0:06:21.760
<v Speaker 1>status change in the future thanks to things like screening

0:06:21.800 --> 0:06:22.360
<v Speaker 1>and prevention.

0:06:22.520 --> 0:06:25.560
<v Speaker 3>Some of our favorite things to talk about, Yes podcast, public.

0:06:25.880 --> 0:06:28.800
<v Speaker 5>Public health, and as much ground as we have covered

0:06:28.800 --> 0:06:31.120
<v Speaker 5>so far in the series and as much as we're

0:06:31.160 --> 0:06:35.000
<v Speaker 5>covering today, it is not everything that has to do

0:06:35.040 --> 0:06:38.000
<v Speaker 5>with cancer. So we want everyone to know that. First

0:06:38.040 --> 0:06:40.599
<v Speaker 5>of all, we have a very very long list of

0:06:40.600 --> 0:06:42.920
<v Speaker 5>sources for every one of these episodes. So if you

0:06:42.960 --> 0:06:46.200
<v Speaker 5>are inspired to learn more about cancer, about cancer, treatment,

0:06:46.240 --> 0:06:49.960
<v Speaker 5>about the epidemiology, about any aspect of cancer, go to

0:06:49.960 --> 0:06:51.640
<v Speaker 5>our website, this podcast with Hey dot com and check

0:06:51.640 --> 0:06:54.200
<v Speaker 5>out the sources list. And these are not the only

0:06:54.240 --> 0:06:55.640
<v Speaker 5>cancer episodes that we're going to do.

0:06:56.040 --> 0:06:56.480
<v Speaker 1>Correct.

0:06:56.640 --> 0:06:58.560
<v Speaker 5>This is sort of what we see as is sort

0:06:58.600 --> 0:07:01.320
<v Speaker 5>of laying the foundation and a jumping off point for

0:07:01.400 --> 0:07:05.440
<v Speaker 5>us to be able to explore individual cancers in the future. Yeah,

0:07:05.520 --> 0:07:08.560
<v Speaker 5>So we would also love your feedback on what episodes

0:07:08.600 --> 0:07:10.320
<v Speaker 5>you'd like to hear more about, what topics you really

0:07:10.360 --> 0:07:11.239
<v Speaker 5>want to learn more about.

0:07:11.400 --> 0:07:13.680
<v Speaker 1>Yeah, it really, it really does help us. Like we

0:07:14.080 --> 0:07:17.200
<v Speaker 1>are already planning next episodes, not just for cancer, but

0:07:17.200 --> 0:07:19.440
<v Speaker 1>for many other things. And it's like, what do what

0:07:19.720 --> 0:07:21.560
<v Speaker 1>do you all want to know about?

0:07:21.680 --> 0:07:25.600
<v Speaker 5>Yeah, what questions arise? Yes, tell us right, see what.

0:07:25.560 --> 0:07:25.920
<v Speaker 3>We can do.

0:07:26.040 --> 0:07:28.920
<v Speaker 1>We'll see what we can do. Also, you know, we

0:07:28.920 --> 0:07:33.400
<v Speaker 1>we're approaching cancer from a very biological perspective, historical perspective.

0:07:33.840 --> 0:07:38.680
<v Speaker 1>The focus is on cancer as this phenomenon, thing, this thing,

0:07:38.920 --> 0:07:42.280
<v Speaker 1>and so in throughout these episodes, we haven't really touched

0:07:42.400 --> 0:07:45.120
<v Speaker 1>very much on the personal experience of cancer and what

0:07:45.280 --> 0:07:48.240
<v Speaker 1>that can look like for somebody, whether that's somebody who

0:07:48.640 --> 0:07:52.040
<v Speaker 1>has been diagnosed, someone undergoing treatment, someone who's loved one

0:07:52.080 --> 0:07:55.120
<v Speaker 1>has been diagnosed. Maybe you're a caretaker, maybe you're the

0:07:55.160 --> 0:07:58.120
<v Speaker 1>friend or colleague. And our first had accounts have been

0:07:58.160 --> 0:08:01.160
<v Speaker 1>so invaluable for to share aring just some of those

0:08:01.200 --> 0:08:04.480
<v Speaker 1>perspectives on that experience. So again, thank you.

0:08:04.560 --> 0:08:04.920
<v Speaker 3>Thank you.

0:08:05.240 --> 0:08:08.000
<v Speaker 5>We really truly can't say it enough. These first hand

0:08:08.000 --> 0:08:11.200
<v Speaker 5>accounts mean so much to us and they make this

0:08:11.360 --> 0:08:14.360
<v Speaker 5>series what it is and our podcast and our podcast

0:08:14.360 --> 0:08:14.840
<v Speaker 5>in general.

0:08:14.920 --> 0:08:18.400
<v Speaker 1>Yeah, so thank you, thank you. One piece of business

0:08:18.400 --> 0:08:22.200
<v Speaker 1>before the last piece of business and that so last week,

0:08:22.200 --> 0:08:24.680
<v Speaker 1>if you listened to our treatment episode, I shouted out

0:08:24.680 --> 0:08:26.960
<v Speaker 1>a couple of episodes of Advances and Care, which is

0:08:27.000 --> 0:08:31.440
<v Speaker 1>another podcast that I host that interviews physician scientists at

0:08:31.440 --> 0:08:34.040
<v Speaker 1>New York Presbyterian and talks about some of the incredible

0:08:34.040 --> 0:08:36.599
<v Speaker 1>cutting edge work that they do. And I want to

0:08:36.640 --> 0:08:39.040
<v Speaker 1>shout out another episode that's related to kind of the

0:08:39.080 --> 0:08:43.120
<v Speaker 1>topic today, which is Screening Prevention, Epidemiology of Cancer, and

0:08:43.160 --> 0:08:48.000
<v Speaker 1>that is episode thirty five titled rise in Early onset

0:08:48.080 --> 0:08:52.560
<v Speaker 1>colon Cancer being Studied through single cell Sequencing. Oh very cool.

0:08:52.800 --> 0:08:56.800
<v Speaker 1>It features research done by Joel Gabrie to look for

0:08:56.920 --> 0:08:59.360
<v Speaker 1>clues that underlie this issue, like why are we seeing

0:08:59.640 --> 0:09:03.240
<v Speaker 1>colon cancer rise in younger adults?

0:09:03.320 --> 0:09:03.480
<v Speaker 2>Right?

0:09:04.160 --> 0:09:05.240
<v Speaker 1>Because it's a scary thing.

0:09:05.160 --> 0:09:07.320
<v Speaker 5>It really is, and it's a lot of headlines. So

0:09:07.320 --> 0:09:09.360
<v Speaker 5>there's a lot of good information there. So check out

0:09:09.360 --> 0:09:10.120
<v Speaker 5>Advances and Care.

0:09:10.160 --> 0:09:12.920
<v Speaker 1>Advances and Care available wherever you get your podcasts.

0:09:13.400 --> 0:09:17.720
<v Speaker 3>Last, but not least, Quarantine any time if.

0:09:17.559 --> 0:09:19.240
<v Speaker 5>You were this is the last time we're going to

0:09:19.320 --> 0:09:22.320
<v Speaker 5>say that, yes, then it will just be taken for

0:09:22.360 --> 0:09:23.120
<v Speaker 5>granted after.

0:09:22.960 --> 0:09:26.120
<v Speaker 1>That starting Yes, we figured this was this series was

0:09:26.160 --> 0:09:30.360
<v Speaker 1>a good time to stop including alcohol in our quarantini recipes.

0:09:30.400 --> 0:09:32.400
<v Speaker 1>We're still going to call them quarantinies because it's too

0:09:32.400 --> 0:09:33.440
<v Speaker 1>good of a name to pass up.

0:09:33.679 --> 0:09:33.920
<v Speaker 3>Nice.

0:09:34.160 --> 0:09:36.680
<v Speaker 1>This week's quarantini is the Crab.

0:09:36.840 --> 0:09:39.640
<v Speaker 3>The Crab, the crab. It's an afo gatto, which means

0:09:39.880 --> 0:09:44.079
<v Speaker 3>espresso and ice cream delicious, so good.

0:09:44.200 --> 0:09:45.400
<v Speaker 1>It just sounded good to us.

0:09:45.400 --> 0:09:45.640
<v Speaker 6>It did.

0:09:45.760 --> 0:09:46.679
<v Speaker 1>That's the whole thing.

0:09:46.720 --> 0:09:48.120
<v Speaker 3>There's nothing deeper behind it.

0:09:48.280 --> 0:09:50.760
<v Speaker 1>The crab means cancer like that is, if you listen

0:09:50.800 --> 0:09:53.400
<v Speaker 1>to the first episode you would know. But anyway, I

0:09:53.520 --> 0:09:53.760
<v Speaker 1>think a.

0:09:53.720 --> 0:09:55.360
<v Speaker 5>Lot of people know that because it's like a what

0:09:55.400 --> 0:09:57.480
<v Speaker 5>do you call it? Star sign thing?

0:09:57.679 --> 0:09:58.319
<v Speaker 1>Astrology?

0:09:58.400 --> 0:10:03.080
<v Speaker 5>Yeah, astrology, yeah, astrology, not astronomy that start sign.

0:10:03.200 --> 0:10:04.520
<v Speaker 1>Yeah, yes.

0:10:04.640 --> 0:10:08.199
<v Speaker 5>Anyways, So check out our social media like Instagram and

0:10:08.320 --> 0:10:11.680

0:10:25.160 --> 0:10:27.920
<v Speaker 1>There's got to be something cool that's there that we've missed.

0:10:29.320 --> 0:10:31.720
<v Speaker 3>Anyways, moving on, we should update our website.

0:10:32.000 --> 0:10:34.280
<v Speaker 1>Moving on break.

0:10:34.440 --> 0:10:36.720
<v Speaker 5>Sure, yeah, yeah great, but then tell me all about

0:10:36.800 --> 0:10:38.720
<v Speaker 5>where we got to how we I'll do all that.

0:10:38.840 --> 0:10:39.400
<v Speaker 1>Yeah, thank you.

0:10:56.080 --> 0:10:58.679
<v Speaker 7>My story of brain cancer starts when I got COVID.

0:10:59.320 --> 0:11:02.440
<v Speaker 7>COVID was still at best. Weeks after I developed a

0:11:02.480 --> 0:11:05.480
<v Speaker 7>weird loss of my voice that wouldn't go away. After

0:11:05.520 --> 0:11:08.079
<v Speaker 7>seeing an E and T and getting tests, I was

0:11:08.120 --> 0:11:11.679
<v Speaker 7>diagnosed with focal cord paralysis, most likely from the virus.

0:11:12.559 --> 0:11:15.320
<v Speaker 7>One scain done was an MRI. I took it home,

0:11:15.440 --> 0:11:17.960
<v Speaker 7>took a look, and that's when I saw a hazy

0:11:18.000 --> 0:11:20.880
<v Speaker 7>blob in my frontal lobe, which I named abby normal.

0:11:21.880 --> 0:11:24.360
<v Speaker 7>I could tell from my doctor's reactions it was serious.

0:11:24.800 --> 0:11:27.120
<v Speaker 7>I was shuffled from doctor to doctor, and a couple

0:11:27.080 --> 0:11:29.320
<v Speaker 7>of weeks ended up at a brain tumor center, being

0:11:29.360 --> 0:11:33.240
<v Speaker 7>told it's most likely brain cancer and they recommended surgery.

0:11:34.000 --> 0:11:36.959
<v Speaker 7>During that time, I was convinced I was dying. All

0:11:37.000 --> 0:11:38.840
<v Speaker 7>I could think about was I'll be dead that year.

0:11:39.640 --> 0:11:43.600
<v Speaker 7>I wanted Abby out. I wanted surgery yesterday. I needed

0:11:43.640 --> 0:11:46.240
<v Speaker 7>to know what this was. A month later, I was

0:11:46.240 --> 0:11:48.680
<v Speaker 7>in surgery, having a two and a half centimeter piece

0:11:48.840 --> 0:11:52.840
<v Speaker 7>of my frontal lobe removed. Recovery was rough, between the

0:11:52.840 --> 0:11:56.120
<v Speaker 7>brain healing effects and very high doses of steroids. I

0:11:56.200 --> 0:11:58.760
<v Speaker 7>gained twenty pounds and had an odd urge to steal

0:11:58.840 --> 0:12:02.200
<v Speaker 7>stupid things. I still remember the half dead plant with

0:12:02.280 --> 0:12:04.240
<v Speaker 7>a post a note that said plant on it. I

0:12:04.360 --> 0:12:08.000
<v Speaker 7>so desperately wanted to steal from a local smoothie place.

0:12:09.480 --> 0:12:11.520
<v Speaker 7>Three and a half years later, I no longer want

0:12:11.559 --> 0:12:14.480
<v Speaker 7>to steal. That was short lived, and I don't notice

0:12:14.480 --> 0:12:18.840
<v Speaker 7>my missing friend. I have oligodendroglioma, and probably had it

0:12:18.880 --> 0:12:23.040
<v Speaker 7>for several years before discovering it accidentally. I consider myself

0:12:23.120 --> 0:12:28.520
<v Speaker 7>lucky finding it so small before seizures. After recovery, I

0:12:28.559 --> 0:12:31.480
<v Speaker 7>went on my surviving death tour. I said yes to everything,

0:12:31.520 --> 0:12:34.720
<v Speaker 7>and I had a blast. I realized who my friends are.

0:12:34.840 --> 0:12:37.160
<v Speaker 7>I saw how amazing of a support system I have,

0:12:37.640 --> 0:12:40.520
<v Speaker 7>and I will always remember and be grateful. I will

0:12:40.520 --> 0:12:44.839
<v Speaker 7>also always remember that plant. I see my doctors two

0:12:44.920 --> 0:12:47.319
<v Speaker 7>times a year looking for growth, and chances are i'll

0:12:47.360 --> 0:12:50.439
<v Speaker 7>have more treatment. While I do believe it will one

0:12:50.480 --> 0:12:54.480
<v Speaker 7>day kill me, that knowledge is oddly freeing. Even if

0:12:54.520 --> 0:12:59.040
<v Speaker 7>it sucks. My cancer doesn't define me, doesn't define my life.

0:12:59.120 --> 0:13:00.520
<v Speaker 7>I'm still living it to its fullest.

0:13:02.760 --> 0:13:06.800
<v Speaker 6>Hello. My name is April Rideout. My brother James Carl

0:13:06.880 --> 0:13:11.960
<v Speaker 6>ride Out was diagnosed with a acute lymphoblastic leukemia all

0:13:12.520 --> 0:13:16.040
<v Speaker 6>in twenty seventeen, and the cancer returned in twenty twenty one.

0:13:17.080 --> 0:13:19.920
<v Speaker 6>He passed in March to twenty twenty three from complications

0:13:19.960 --> 0:13:23.440
<v Speaker 6>related to graph versus host disease. I like to share

0:13:23.480 --> 0:13:26.120
<v Speaker 6>his story of his first cancer diagnosis and his own

0:13:26.200 --> 0:13:29.720
<v Speaker 6>words from twenty eighteen to twenty nineteen at a dinner

0:13:29.760 --> 0:13:32.960
<v Speaker 6>honoring the nurses who cared for him with love, kindness,

0:13:33.080 --> 0:13:36.840
<v Speaker 6>and understanding. Before I was diagnosed, I was a happy,

0:13:36.880 --> 0:13:40.640
<v Speaker 6>go lucky staff accountant doing motor fuel tax, married to

0:13:40.679 --> 0:13:43.199
<v Speaker 6>my beautiful wife Amanda, and we just got a wonderful

0:13:43.240 --> 0:13:46.400
<v Speaker 6>dog named Indy. But come the beginning of July in

0:13:46.440 --> 0:13:51.079
<v Speaker 6>twenty seventeen, I started not feeling right. I had dizzy spells,

0:13:51.280 --> 0:13:53.280
<v Speaker 6>I had pain in my right foot along with other

0:13:53.320 --> 0:13:56.800
<v Speaker 6>symptoms as well as lightheadedness. I started to look like

0:13:56.880 --> 0:14:01.040
<v Speaker 6>Uncle Fester, to be honest, and on July nineteen, twenty seventeen,

0:14:01.160 --> 0:14:03.800
<v Speaker 6>my boss Larry told me to leave because I looked

0:14:03.840 --> 0:14:05.959
<v Speaker 6>like crap and I had to go to the doctor,

0:14:06.000 --> 0:14:08.600
<v Speaker 6>and my wonderful wife suggested that they do a blood test.

0:14:09.200 --> 0:14:11.200
<v Speaker 6>Come to find out, the doctors there told me to

0:14:11.200 --> 0:14:13.800
<v Speaker 6>go to the er, and then from that er they

0:14:13.800 --> 0:14:16.200
<v Speaker 6>did an additional blood test and found out that I

0:14:16.240 --> 0:14:19.400
<v Speaker 6>have leukemia because I had over one hundred and ninety

0:14:19.440 --> 0:14:22.960
<v Speaker 6>seven thousand white blood cells in my body, and if

0:14:23.000 --> 0:14:25.240
<v Speaker 6>I waited even one day, I would have passed away.

0:14:26.600 --> 0:14:30.600
<v Speaker 6>Lying in the hospital in complete terror. I seriously thought

0:14:30.600 --> 0:14:33.240
<v Speaker 6>my life was going to end that day. Horror was

0:14:33.360 --> 0:14:36.240
<v Speaker 6>all across the room, from my immediate family to my wife.

0:14:36.640 --> 0:14:39.280
<v Speaker 6>But after the news had struck, we started working on

0:14:39.320 --> 0:14:42.960
<v Speaker 6>a treatment plan. One week later, we determined for research

0:14:43.080 --> 0:14:46.800
<v Speaker 6>and diligence that Virginia G. Piper was the answer and

0:14:46.840 --> 0:14:49.440
<v Speaker 6>we moved me there from the hospital I was at.

0:14:49.800 --> 0:14:52.240
<v Speaker 6>For the course of my many stays there, the constant

0:14:52.240 --> 0:14:54.720
<v Speaker 6>pleasure was the nursing staff, and because of them and

0:14:54.760 --> 0:14:57.160
<v Speaker 6>the doctors and the treatment plan, which was a stem

0:14:57.200 --> 0:15:00.560
<v Speaker 6>cell transplant, I have been remissioned for for a year

0:15:00.600 --> 0:15:04.360
<v Speaker 6>and beat the crap out of cancer. Thank you for

0:15:04.400 --> 0:15:07.840
<v Speaker 6>the opportunity to share James's words. He always wanted to

0:15:07.880 --> 0:15:11.000
<v Speaker 6>publish a book on his experiences with cancer, and this

0:15:11.080 --> 0:15:12.960
<v Speaker 6>is a lovely way to honor that wish of his.

0:15:13.880 --> 0:15:17.200
<v Speaker 6>Every year, my family keeps James's memory alive by attending

0:15:17.240 --> 0:15:20.600
<v Speaker 6>and raising donations for Blood Cancer United's Light the Night event.

0:15:21.160 --> 0:15:50.560
<v Speaker 1>Thank you. Let's spend a moment taking stock of what

0:15:50.560 --> 0:15:51.440
<v Speaker 1>we've learned so far.

0:15:51.720 --> 0:15:52.560
<v Speaker 3>I love that idea.

0:15:52.640 --> 0:15:57.320
<v Speaker 1>Okay, we have learned what cancer is, uncontrolled cell proliferation.

0:15:58.120 --> 0:16:01.800
<v Speaker 1>We've learned why it's so common. It's an unavoidable consequence

0:16:01.880 --> 0:16:06.440
<v Speaker 1>of multicellularity. We've learned how we treat the forty percent

0:16:06.440 --> 0:16:09.440
<v Speaker 1>of the population that will develop cancer in their lifetime.

0:16:09.960 --> 0:16:14.480
<v Speaker 1>And we've learned that, despite these treatment advances, seventeen percent

0:16:14.520 --> 0:16:18.400
<v Speaker 1>of the population will die from cancer. But what we

0:16:18.520 --> 0:16:22.320
<v Speaker 1>haven't addressed yet in any great detail are those numbers

0:16:22.720 --> 0:16:26.800
<v Speaker 1>forty percent and seventeen percent. For much of the twentieth century,

0:16:27.200 --> 0:16:30.480
<v Speaker 1>cancer research efforts were directed towards finding a cure for

0:16:30.560 --> 0:16:33.360
<v Speaker 1>that forty percent, and as you shared with us last week, Aarin,

0:16:33.760 --> 0:16:36.960
<v Speaker 1>we have made incredible headway in that regard for many,

0:16:37.160 --> 0:16:41.920
<v Speaker 1>though not all, types of cancer. Despite these innovations, cancer

0:16:41.960 --> 0:16:47.400
<v Speaker 1>treatment can be grueling. It can be expensive, prohibitedly so

0:16:47.760 --> 0:16:51.760
<v Speaker 1>in some cases, and that expense mostly refers to the US.

0:16:52.160 --> 0:16:55.880
<v Speaker 1>It often includes debilitating side effects, It can lead to

0:16:55.920 --> 0:16:59.200
<v Speaker 1>long term issues, including increasing the risk of developing a

0:16:59.200 --> 0:17:04.119
<v Speaker 1>second cancer, and it comes with no guarantee. What has

0:17:04.240 --> 0:17:08.600
<v Speaker 1>received far less attention in cancer research historically is how

0:17:08.640 --> 0:17:13.119
<v Speaker 1>to reduce the number of people getting cancer or needing treatment,

0:17:13.280 --> 0:17:16.600
<v Speaker 1>or needing advanced treatment in the first place. Right, Like,

0:17:17.160 --> 0:17:21.040
<v Speaker 1>that's received a much smaller piece of the pie as usual.

0:17:20.880 --> 0:17:21.680
<v Speaker 3>With public health.

0:17:21.960 --> 0:17:27.640
<v Speaker 1>Yes, yes, which and there's more, there's understandable blah blah blah.

0:17:27.640 --> 0:17:30.720
<v Speaker 1>People need solutions right now. Yeah, I know there's a

0:17:30.760 --> 0:17:34.080
<v Speaker 1>lot that goes into it. Yeah, given what we know

0:17:34.720 --> 0:17:37.640
<v Speaker 1>about what we've learned so far about the evolution of cancer,

0:17:37.880 --> 0:17:40.800
<v Speaker 1>we're unlikely to ever bring that forty percent all the

0:17:40.800 --> 0:17:43.080
<v Speaker 1>way down to zero, that lifetime risk of forty all

0:17:43.119 --> 0:17:46.480
<v Speaker 1>the way down to zero. But with prevention, we can

0:17:46.480 --> 0:17:49.600
<v Speaker 1>make it part of the way there. Cutting edge treatments

0:17:49.720 --> 0:17:53.280
<v Speaker 1>might increase survival for those with cancer, giving people more

0:17:53.320 --> 0:17:56.160
<v Speaker 1>precious time with their loved ones. But if we can

0:17:56.200 --> 0:17:59.720
<v Speaker 1>intervene earlier through screening, we may be able to shrink

0:17:59.720 --> 0:18:06.280
<v Speaker 1>that's seventeen percent significantly significantly. Prevention and screening, though cornerstones

0:18:06.320 --> 0:18:09.560
<v Speaker 1>of cancer care fail to get the appreciation they rightfully

0:18:09.600 --> 0:18:13.359
<v Speaker 1>deserve naps. I mean, and that's historically as well as today.

0:18:13.400 --> 0:18:17.320
<v Speaker 1>It continues to today. This is not surprising again, like this,

0:18:17.320 --> 0:18:21.000
<v Speaker 1>this concept about public health being invisible until it fails.

0:18:22.040 --> 0:18:25.000
<v Speaker 1>So I'm gonna spend We're gonna spend this episode making

0:18:25.040 --> 0:18:27.520
<v Speaker 1>cancer prevention and screening more visible.

0:18:27.680 --> 0:18:27.840
<v Speaker 8>Ah.

0:18:27.880 --> 0:18:34.040
<v Speaker 1>I love this. Cancer prevention, prevention of any kind requires

0:18:34.119 --> 0:18:38.600
<v Speaker 1>linking cause to effect. Yes, yes, Why did death from

0:18:38.680 --> 0:18:42.840
<v Speaker 1>infectious diseases drop over the twentieth century? Largely because germ

0:18:42.880 --> 0:18:45.800
<v Speaker 1>theory gave us the mechanism, and then we applied that

0:18:45.920 --> 0:18:51.280
<v Speaker 1>knowledge to prevention via vaccines, sanitation, and hygiene. Cancer's cause

0:18:51.280 --> 0:18:54.879
<v Speaker 1>and effect relationship is quite a bit more complex than that.

0:18:54.800 --> 0:18:56.640
<v Speaker 3>If we didn't make that clear in episode two.

0:18:56.960 --> 0:19:00.880
<v Speaker 1>Yeah, and namely because there isn't just one cause and

0:19:01.000 --> 0:19:05.320
<v Speaker 1>one affect one mechanism, but there's a dizzying number of

0:19:05.400 --> 0:19:08.119
<v Speaker 1>all of these different things, some of which are completely

0:19:08.119 --> 0:19:11.200
<v Speaker 1>beyond our control, or at least beyond our control as

0:19:11.240 --> 0:19:15.359
<v Speaker 1>we know it right now, or as individuals. As individuals, Yes,

0:19:15.520 --> 0:19:19.159
<v Speaker 1>like a random mutation that might just happen It happens

0:19:19.160 --> 0:19:22.359
<v Speaker 1>all the time. Actually, so how can we ever prevent

0:19:22.400 --> 0:19:26.399
<v Speaker 1>that or link that? So disentangling that web has proven

0:19:26.840 --> 0:19:30.280
<v Speaker 1>quite the challenge, but we have had some success. And

0:19:30.359 --> 0:19:32.639
<v Speaker 1>as I go through a few case studies in our

0:19:32.720 --> 0:19:35.760
<v Speaker 1>centuries long quest to understand the drivers of cancer, I

0:19:35.800 --> 0:19:37.800
<v Speaker 1>want you to take note of two things.

0:19:37.800 --> 0:19:38.119
<v Speaker 3>Okay.

0:19:38.600 --> 0:19:43.600
<v Speaker 1>Number one, establishing a causal relationship is often difficult and

0:19:43.840 --> 0:19:48.600
<v Speaker 1>it takes time. And number two, knowledge alone is not enough.

0:19:48.680 --> 0:19:49.320
<v Speaker 3>Oh my gosh.

0:19:49.359 --> 0:19:52.720
<v Speaker 1>There also has to be political will and public buy

0:19:52.760 --> 0:19:54.160
<v Speaker 1>in for it to have an impact.

0:19:54.359 --> 0:19:55.239
<v Speaker 3>I already love this.

0:19:55.400 --> 0:19:55.639
<v Speaker 8>That's it.

0:19:55.680 --> 0:19:59.280
<v Speaker 1>I mean, that's the end of the episode. Now, okay,

0:20:00.240 --> 0:20:02.840
<v Speaker 1>if you lived in London in the eighteenth century, you

0:20:02.920 --> 0:20:06.320
<v Speaker 1>probably kept your home warm by burning coal see our

0:20:06.359 --> 0:20:10.840
<v Speaker 1>London smoger. So in which case you probably had a chimney,

0:20:11.240 --> 0:20:14.359
<v Speaker 1>in which case you probably hired a chimney sweep to

0:20:14.440 --> 0:20:19.080
<v Speaker 1>clean out the accumulated soot. That chimney sweep was probably

0:20:19.280 --> 0:20:21.160
<v Speaker 1>between four and ten years old.

0:20:21.280 --> 0:20:22.119
<v Speaker 3>Oh my gosh.

0:20:22.320 --> 0:20:25.960
<v Speaker 1>Yes, oh, was forced to work naked and bathed about

0:20:25.960 --> 0:20:26.560
<v Speaker 1>once a year.

0:20:28.359 --> 0:20:33.000
<v Speaker 3>Oh wow wow. Okay, yeah, four and ten year olds

0:20:33.000 --> 0:20:33.920
<v Speaker 3>four and ten year olds.

0:20:34.040 --> 0:20:38.680
<v Speaker 1>Yeah, there are many issues with the situation. Yes. Yeah, So,

0:20:38.760 --> 0:20:43.240
<v Speaker 1>as English physician Percival Pot described in seventeen seventy five, quote,

0:20:43.520 --> 0:20:46.560
<v Speaker 1>in their early infancy, they are most frequently treated with

0:20:46.680 --> 0:20:49.879
<v Speaker 1>great brutality and are almost starved with cold and hunger.

0:20:50.280 --> 0:20:53.320
<v Speaker 1>They are thrust up narrow and sometimes hot chimneys where

0:20:53.320 --> 0:20:56.520
<v Speaker 1>they are bruised, burned, and almost suffocated, and when they

0:20:56.520 --> 0:21:01.320
<v Speaker 1>get to puberty, become peculiarly liable to a most noisome, painful,

0:21:01.400 --> 0:21:07.480
<v Speaker 1>and fatal disease. End quote. That disease was chimney sweeps cancer. Okay,

0:21:08.920 --> 0:21:10.399
<v Speaker 1>have you ever heard of cancer?

0:21:10.400 --> 0:21:10.640
<v Speaker 6>Okay?

0:21:11.480 --> 0:21:15.680
<v Speaker 1>Pot's description of the quote unquote sootwart and subsequent metastasis.

0:21:15.680 --> 0:21:18.720
<v Speaker 1>So it started out as a footwart and then metastasized.

0:21:19.200 --> 0:21:22.880
<v Speaker 1>It ranks among the earliest, if not the first observations

0:21:22.920 --> 0:21:28.320
<v Speaker 1>of occupational cancer. Really really yeah, in babies and baby So,

0:21:28.440 --> 0:21:31.399
<v Speaker 1>what would happen was that these chimney sweeps would, uh,

0:21:31.960 --> 0:21:36.200
<v Speaker 1>it would be exposed to all of the everything. Yeah, constantly,

0:21:36.280 --> 0:21:38.880
<v Speaker 1>there would be like a sore that arose, a sootwart,

0:21:39.080 --> 0:21:42.119
<v Speaker 1>and then that would eventually metastasize as they went into adolescence. Oh,

0:21:42.320 --> 0:21:45.640
<v Speaker 1>was they went through puberty? Yeah, And so his report

0:21:45.760 --> 0:21:48.040
<v Speaker 1>on this. He wrote a report that was like describing

0:21:48.200 --> 0:21:52.359
<v Speaker 1>what happened, describing the inhumane conditions, and it spurred the

0:21:52.359 --> 0:21:55.440
<v Speaker 1>publication of other case studies and people were like, oh, yeah,

0:21:55.440 --> 0:21:57.280
<v Speaker 1>I've seen this. I had chalked it up to something

0:21:57.320 --> 0:21:59.960
<v Speaker 1>else before. Yeah. So it was like a lot of

0:22:00.080 --> 0:22:01.680
<v Speaker 1>these case studies that came out and came out and

0:22:01.720 --> 0:22:04.320
<v Speaker 1>came out, and that like there was a public outcry.

0:22:04.480 --> 0:22:06.080
<v Speaker 1>I was like, we have to do something about this.

0:22:06.080 --> 0:22:11.439
<v Speaker 1>This is awful, and it's it's hard to imagine anyone

0:22:11.680 --> 0:22:14.240
<v Speaker 1>making the argument that like, oh, these chimney sweeps are

0:22:14.280 --> 0:22:17.200
<v Speaker 1>perfectly fine for four years old is plenty old enough

0:22:17.200 --> 0:22:20.840
<v Speaker 1>to work in a chimney on your own, right, But

0:22:20.880 --> 0:22:24.600
<v Speaker 1>people did make that argument, Oh yeah, yeah, And it

0:22:24.640 --> 0:22:28.760
<v Speaker 1>took decades for any meaningful policy changing this to be passed.

0:22:29.080 --> 0:22:31.640
<v Speaker 1>In seventeen eighty eight, so this is thirteen years after

0:22:31.840 --> 0:22:35.800
<v Speaker 1>Pott's observation, the minimum age requirement for a chimney sweep

0:22:35.840 --> 0:22:40.520
<v Speaker 1>was raised to eight years old. Oh my goodness, No,

0:22:40.920 --> 0:22:42.120
<v Speaker 1>there's so much more, Like.

0:22:42.080 --> 0:22:44.719
<v Speaker 5>There's so many weaves that is blowing my start. No,

0:22:45.000 --> 0:22:47.920
<v Speaker 5>you know what I knew about chimney sweeps. Erin Mary Poppins.

0:22:48.440 --> 0:22:50.800
<v Speaker 1>Yeah, no, that's all I knew. That would be like

0:22:51.119 --> 0:22:53.800
<v Speaker 1>pasted eighteen seventy five, which is when the next legislation,

0:22:54.000 --> 0:22:57.080
<v Speaker 1>meaningful legislation was passed, like one hundred years l one

0:22:57.160 --> 0:23:00.719
<v Speaker 1>hundred years after his observation was published. Oh my, So

0:23:00.800 --> 0:23:03.360
<v Speaker 1>this is when the Chimney Sweepers Act was passed, and

0:23:03.400 --> 0:23:07.040
<v Speaker 1>this forbade any children from sweeping chimneys, and it introduced

0:23:07.040 --> 0:23:10.320
<v Speaker 1>a licensing system that helped with enforcements, so like you

0:23:10.359 --> 0:23:13.320
<v Speaker 1>could not sweep a chimney unless you were an adult,

0:23:13.400 --> 0:23:15.679
<v Speaker 1>and it was at sixteen years old. I don't know, Okay,

0:23:15.720 --> 0:23:20.040
<v Speaker 1>who knows, but still right, Pot's observation was just that

0:23:20.200 --> 0:23:23.159
<v Speaker 1>it was an observation, okay, end of he didn't have

0:23:23.160 --> 0:23:27.560
<v Speaker 1>supporting statistics. Soot was not proven as a carcinogen until

0:23:27.640 --> 0:23:31.520
<v Speaker 1>nineteen twenty two, when researchers induced cancer in mice after

0:23:31.600 --> 0:23:32.679
<v Speaker 1>exposure to soot.

0:23:32.880 --> 0:23:33.400
<v Speaker 8>Wow.

0:23:33.440 --> 0:23:35.680
<v Speaker 1>So it was sort of like there was this hypothetical tank,

0:23:35.880 --> 0:23:38.080
<v Speaker 1>like this theoretical link that was like, well, clearly this

0:23:38.119 --> 0:23:40.120
<v Speaker 1>is the exposure one to one.

0:23:40.000 --> 0:23:42.880
<v Speaker 3>But they just never put that like directly together.

0:23:42.760 --> 0:23:45.000
<v Speaker 1>And like what is it about soot? Yeah, that kind

0:23:45.040 --> 0:23:49.280
<v Speaker 1>of thing would those laws have been passed sooner if

0:23:49.320 --> 0:23:53.240
<v Speaker 1>he had that information earlier. The story of cigarettes and

0:23:53.280 --> 0:23:56.080
<v Speaker 1>cancer would suggest that no, not necessarily.

0:23:56.160 --> 0:23:59.040
<v Speaker 5>I mean, especially when it sounds like they were kids

0:23:59.320 --> 0:24:03.159
<v Speaker 5>who weren't well taken care.

0:24:03.040 --> 0:24:05.120
<v Speaker 1>Of marginalized communities.

0:24:05.160 --> 0:24:09.040
<v Speaker 5>Yeah, yeah, yo, Aaron, Yeah.

0:24:08.600 --> 0:24:10.800
<v Speaker 1>I mean and in fact, when you look at the

0:24:10.880 --> 0:24:15.159
<v Speaker 1>timeline for like the initial observation of chimney chimney sweeps

0:24:15.200 --> 0:24:19.360
<v Speaker 1>cancer to then you know, policy change for that, that

0:24:19.520 --> 0:24:24.320
<v Speaker 1>timeline seems downright speedy compared to cigarettes and cancer.

0:24:24.520 --> 0:24:26.480
<v Speaker 3>Just curious, by the way, what kind of cancer is

0:24:26.520 --> 0:24:27.480
<v Speaker 3>chimney sweeps cancer?

0:24:27.640 --> 0:24:28.639
<v Speaker 1>Chimney sweeps cancer?

0:24:29.240 --> 0:24:31.639
<v Speaker 3>I mean does it have like is it testicular cancers?

0:24:31.640 --> 0:24:32.280
<v Speaker 3>That love cancer?

0:24:32.560 --> 0:24:35.600
<v Speaker 1>It's like scrodle cancer? Okay yeah yeah yeah sorry.

0:24:35.800 --> 0:24:37.240
<v Speaker 5>I was like I thought that you said that in

0:24:37.240 --> 0:24:38.959
<v Speaker 5>the first episode, but I couldn't remember.

0:24:39.000 --> 0:24:41.240
<v Speaker 3>It's in the name chimneys.

0:24:41.480 --> 0:24:41.800
<v Speaker 9>I know.

0:24:42.480 --> 0:24:44.760
<v Speaker 3>We talked about how you have to define a cancer

0:24:44.840 --> 0:24:45.359
<v Speaker 3>to go back.

0:24:45.280 --> 0:24:45.960
<v Speaker 1>To page too.

0:24:46.040 --> 0:24:53.320
<v Speaker 5>Yeah okay, thank you, No, that makes sense, yeah yeah yeah.

0:24:53.359 --> 0:24:55.360
<v Speaker 1>And it's because they were sweeping chimneys naked like they

0:24:55.359 --> 0:24:56.359
<v Speaker 1>were there was nothing.

0:24:56.560 --> 0:24:59.560
<v Speaker 5>Yeah, and like as in development, you're like then with

0:24:59.640 --> 0:25:01.800
<v Speaker 5>puber all of the hormones and.

0:25:01.960 --> 0:25:07.119
<v Speaker 1>Okay, yeah, yeah, yeah, yeah, yeah, cell proliferation, et cetera. Yeah, Okay, So,

0:25:07.600 --> 0:25:12.679
<v Speaker 1>of all the recognized carcinogens today, tobacco is probably the

0:25:12.720 --> 0:25:15.040
<v Speaker 1>most well known. Like, if you ask someone lists some

0:25:15.160 --> 0:25:18.119
<v Speaker 1>carcinogens for me, probably cigarettes woul be the number one

0:25:18.160 --> 0:25:19.000
<v Speaker 1>for sure, number one.

0:25:18.920 --> 0:25:21.160
<v Speaker 5>And I mean rightfully so in terms of the number

0:25:21.200 --> 0:25:22.400
<v Speaker 5>of people it kills every year.

0:25:22.480 --> 0:25:25.399
<v Speaker 1>Absolutely, yeah, yeah. And I think this is also a

0:25:25.440 --> 0:25:29.760
<v Speaker 1>real demonstration of the power of awareness campaigns, all those ads,

0:25:29.840 --> 0:25:34.360
<v Speaker 1>I remember those ads. Yeah. This notoriety, though, was incredibly

0:25:34.400 --> 0:25:37.879
<v Speaker 1>hard won, with decades of big tobacco sewing doubt and

0:25:37.960 --> 0:25:42.439
<v Speaker 1>obfuscating the facts, a reluctant public, and a government afraid

0:25:42.520 --> 0:25:45.760
<v Speaker 1>to take a stance, even if that meant preventing tens

0:25:45.800 --> 0:25:50.560
<v Speaker 1>of thousands of deaths. Someday we will cover the story

0:25:50.600 --> 0:25:53.840
<v Speaker 1>in all its lord detail, but for now, I'm just

0:25:53.840 --> 0:25:56.560
<v Speaker 1>going to give you the bare bones, Okay. Our first

0:25:56.600 --> 0:26:00.800
<v Speaker 1>marker along the timeline takes us to seventeen sixty one,

0:26:01.520 --> 0:26:05.879
<v Speaker 1>with John Hill's publication of his pamphlet titled Cautions against

0:26:05.960 --> 0:26:07.840
<v Speaker 1>the Immoderate Use of Snuff.

0:26:08.720 --> 0:26:11.000
<v Speaker 3>Seventeen sixty one.

0:26:11.960 --> 0:26:16.480
<v Speaker 1>Oh boy, Okay, and in this pamphlet he argued that

0:26:16.680 --> 0:26:21.080
<v Speaker 1>oral tobacco caused lip mouth and throat cancer. Wow. Yeah,

0:26:21.720 --> 0:26:26.560
<v Speaker 1>Unlike percival Pots observation, people largely ridiculed or ignored Hill,

0:26:26.880 --> 0:26:30.960
<v Speaker 1>tobacco was exceedingly popular, and he was telling them something

0:26:31.000 --> 0:26:33.600
<v Speaker 1>that they didn't want to hear. Where's your proof for this, bro,

0:26:33.760 --> 0:26:38.160
<v Speaker 1>don't take this away from pamphlet. Get real that, get real,

0:26:38.200 --> 0:26:42.320
<v Speaker 1>and get out of here. Reaction would remain surprisingly consistent,

0:26:42.560 --> 0:26:46.360
<v Speaker 1>startlingly so, over the next two centuries. In the late

0:26:46.400 --> 0:26:49.959
<v Speaker 1>eighteen hundreds and early nineteen hundreds, Hill's pamphlet had largely

0:26:50.000 --> 0:26:51.120
<v Speaker 1>been forgotten by that.

0:26:51.119 --> 0:26:54.160
<v Speaker 3>Jome just kick it over this seventeen seventeen sixty one.

0:26:55.960 --> 0:26:59.320
<v Speaker 1>I mean, and I wonder too whether anything about like

0:26:59.560 --> 0:27:02.160
<v Speaker 1>imma under it, because like, was that was when did

0:27:02.160 --> 0:27:04.840
<v Speaker 1>the temperance movement begin? Was it that sort of thing

0:27:04.960 --> 0:27:08.080
<v Speaker 1>the woes of modern society, which is always a thing

0:27:08.119 --> 0:27:09.240
<v Speaker 1>that always happens.

0:27:10.040 --> 0:27:12.639
<v Speaker 5>It's just wow, yeah, because that's two hundred years until

0:27:12.680 --> 0:27:14.040
<v Speaker 5>Mad Men where they're.

0:27:14.000 --> 0:27:16.359
<v Speaker 1>Like smoking all the time. Oh my god. Oh, because

0:27:16.359 --> 0:27:19.240
<v Speaker 1>you're watching that, yes, Because last year I was watching

0:27:19.320 --> 0:27:22.560
<v Speaker 1>it was a series and I was like, there's so

0:27:22.680 --> 0:27:25.040
<v Speaker 1>much relevant things for pregnancy. There's so many relevant things

0:27:25.040 --> 0:27:30.480
<v Speaker 1>for cancers. Yes, yeah, so many relevant things for cancer. Yes,

0:27:31.800 --> 0:27:34.760
<v Speaker 1>but yeah so by the time his by the like

0:27:34.800 --> 0:27:38.359
<v Speaker 1>early nineteen hundreds, his pamphlet had long been forgotten, but

0:27:38.480 --> 0:27:43.240
<v Speaker 1>scientists and medical you know, practitioners were forming their own

0:27:43.280 --> 0:27:48.040
<v Speaker 1>suspicions of a tobacco cancer link, more specifically, cigarettes and

0:27:48.119 --> 0:27:51.800
<v Speaker 1>lung cancer. Lung cancer by this time had begun to

0:27:51.840 --> 0:27:56.000
<v Speaker 1>transform from a rarity to like a pretty common diagnosis.

0:27:56.600 --> 0:27:59.240
<v Speaker 1>Research conducted over the first half of the twentieth century

0:27:59.359 --> 0:28:05.240
<v Speaker 1>solidify the cigarettes lung cancer risk, using epidemiological data, animal experimentation,

0:28:05.960 --> 0:28:10.520
<v Speaker 1>cellular research, and chemical analysis of cigarette smoke to show

0:28:10.880 --> 0:28:14.639
<v Speaker 1>beyond a doubt, not just a reasonable doubt, no any doubt,

0:28:15.359 --> 0:28:21.399
<v Speaker 1>that smoking greatly increased the risk of lung cancer. Proven. Yes, proven.

0:28:22.119 --> 0:28:26.480
<v Speaker 1>In nineteen fifty four, cancer authorities in several countries around

0:28:26.520 --> 0:28:31.000
<v Speaker 1>the world announced this unequivocal link, and even big Tobacco

0:28:31.200 --> 0:28:37.919
<v Speaker 1>was convinced, although only privately in memos. Yes, it still

0:28:37.960 --> 0:28:41.840
<v Speaker 1>took another ten years for the US Surgeon General to

0:28:41.880 --> 0:28:45.680
<v Speaker 1>announce that cigarettes are a cause of lung cancer. Pressured

0:28:45.680 --> 0:28:49.480
<v Speaker 1>by the tobacco industry to stay quiet, smoking declined a

0:28:49.520 --> 0:28:52.000
<v Speaker 1>bit after this announcement in nineteen sixty four or so,

0:28:52.440 --> 0:28:56.320
<v Speaker 1>but then it plateaued like it kind of went and

0:28:56.400 --> 0:28:59.160
<v Speaker 1>went back up a little bit until nineteen eighty. And

0:28:59.200 --> 0:29:04.480
<v Speaker 1>that's when broad cast ads ended for cigarettes. Wow yeah,

0:29:04.480 --> 0:29:06.760
<v Speaker 1>because it was like again in mad Men, you know,

0:29:07.040 --> 0:29:09.320
<v Speaker 1>oh well we have this filter. Oh well ours you

0:29:09.400 --> 0:29:12.560
<v Speaker 1>can smoke, but like ours are clean, our health ours

0:29:12.560 --> 0:29:16.600
<v Speaker 1>are this yeah yeah, And so it's like the laws

0:29:16.600 --> 0:29:18.840
<v Speaker 1>had to catch up to like what was allowed to

0:29:18.920 --> 0:29:26.160
<v Speaker 1>be said. And so clearly though, skepticism remained, both in

0:29:26.240 --> 0:29:30.480
<v Speaker 1>the public in politicians everywhere, and this was partly the

0:29:30.520 --> 0:29:34.440
<v Speaker 1>handiwork of big tobacco swing their seas of doubt. Partly

0:29:34.480 --> 0:29:38.640
<v Speaker 1>it was also the lag time between exposure and cancer development,

0:29:38.760 --> 0:29:42.040
<v Speaker 1>which can be decades in the making, and partly because

0:29:42.080 --> 0:29:48.600
<v Speaker 1>cigarettes were well loved and highly addictive. In nineteen sixty five,

0:29:48.680 --> 0:29:51.920
<v Speaker 1>so this is the year after the Surgeon General's announcement,

0:29:52.360 --> 0:29:54.960
<v Speaker 1>fifty percent of men and thirty two percent of women

0:29:55.000 --> 0:30:00.400
<v Speaker 1>in the US smoked wow yeah, okay yeah. The amount

0:30:00.400 --> 0:30:03.560
<v Speaker 1>of cigarettes was also high, about ten per day on

0:30:03.680 --> 0:30:08.000
<v Speaker 1>average something around there, half a pack, half a pack, yeat.

0:30:08.360 --> 0:30:10.640
<v Speaker 1>And then there was a poll that had been conducted

0:30:10.640 --> 0:30:13.680
<v Speaker 1>a few years prior so before the Surgeon General's announcement,

0:30:13.720 --> 0:30:15.440
<v Speaker 1>but after the link had been.

0:30:15.600 --> 0:30:16.440
<v Speaker 3>Very clear shown.

0:30:16.520 --> 0:30:21.520
<v Speaker 1>Yeah, one third of US doctors believed that cigarettes were

0:30:21.560 --> 0:30:25.280
<v Speaker 1>a major cause of lung cancer. Really one third? Only

0:30:25.320 --> 0:30:29.760
<v Speaker 1>one third and forty three percent of doctors smoked regularly. Yeah,

0:30:30.120 --> 0:30:33.200
<v Speaker 1>Tobacco is woven into the history and the culture of

0:30:33.200 --> 0:30:36.360
<v Speaker 1>the US and in so many other countries, and uprooting

0:30:36.400 --> 0:30:40.280
<v Speaker 1>it has proven to be quite difficult. But the decline

0:30:40.320 --> 0:30:44.120
<v Speaker 1>in cigarette consumption since the nineteen eighties, driven by awareness

0:30:44.160 --> 0:30:48.120
<v Speaker 1>campaigns and policy changes like age limits and smoking bands

0:30:48.120 --> 0:30:52.080
<v Speaker 1>in restaurants. I still remember going into restaurants smoking or.

0:30:52.080 --> 0:30:55.120
<v Speaker 3>Non smoking, hotels smoking non smoking. Yeah.

0:30:55.160 --> 0:30:59.160
<v Speaker 1>Yeah. It has led to thousands of lives saved and

0:30:59.400 --> 0:31:03.400
<v Speaker 1>estimated eight hundred thousand lung cancer deaths were averted between

0:31:03.480 --> 0:31:07.000
<v Speaker 1>nineteen sixty four and nineteen eighty five because of reduced smoking.

0:31:07.280 --> 0:31:09.520
<v Speaker 3>Wow, just in those like twenty years.

0:31:09.520 --> 0:31:13.440
<v Speaker 1>In those twenty years, and lung cancer deaths are projected

0:31:13.440 --> 0:31:16.480
<v Speaker 1>to drop seventy nine percent from twenty fifteen to twenty

0:31:16.520 --> 0:31:17.760
<v Speaker 1>sixty five. Wow.

0:31:17.880 --> 0:31:18.720
<v Speaker 3>Yeah, that's great.

0:31:19.080 --> 0:31:22.200
<v Speaker 1>Lung cancer will never be eradicated because while cigarettes are

0:31:22.240 --> 0:31:25.280
<v Speaker 1>the leading cause. They are not the only one, nor

0:31:25.360 --> 0:31:29.760
<v Speaker 1>is sustained progress guaranteed. Smoking has increased in some parts

0:31:29.760 --> 0:31:33.320
<v Speaker 1>of the world. Shock Like, it still blew my mind.

0:31:33.320 --> 0:31:35.120
<v Speaker 3>Well, especially with e cigarettes and vaping.

0:31:36.240 --> 0:31:40.240
<v Speaker 1>Even cigarette smoking has increased. Yeah, Yeah, And air pollution

0:31:40.720 --> 0:31:45.280
<v Speaker 1>remains a major driver of lung cancer. Despite these present

0:31:45.360 --> 0:31:47.920
<v Speaker 1>day hurdles, and despite the centuries long fight to put

0:31:47.960 --> 0:31:50.640
<v Speaker 1>tobacco in the spotlight as a cause of lung cancer,

0:31:50.840 --> 0:31:55.960
<v Speaker 1>this is still a remarkable success story. Yeah, remarkable. Over

0:31:56.000 --> 0:31:58.880
<v Speaker 1>the twentieth and into the twenty first centuries, many other

0:31:58.920 --> 0:32:03.600
<v Speaker 1>carcinogens have been idne Lifestyle factors such as alcohol, red meat,

0:32:03.760 --> 0:32:09.600
<v Speaker 1>processed meats, UV, radiation, occupational exposures like asbestos and silica dust,

0:32:10.120 --> 0:32:14.360
<v Speaker 1>infectious agents like epstein bar virus, Helicobacter pylori which is

0:32:14.400 --> 0:32:18.800
<v Speaker 1>the cause of stomach ulcers, and human papalomavirus see RHPV

0:32:18.800 --> 0:32:22.360
<v Speaker 1>episodes See RHPV episode. These are just a handful of

0:32:22.440 --> 0:32:26.800
<v Speaker 1>known carcinogens. The list of probable carcinogens is much longer.

0:32:27.760 --> 0:32:32.080
<v Speaker 1>What we've done with this information varies. It varies based

0:32:32.080 --> 0:32:35.120
<v Speaker 1>on the individual and when whether you can modify your

0:32:35.120 --> 0:32:38.480
<v Speaker 1>behavior to reduce your exposure. Maybe that means drinking less alcohol.

0:32:38.880 --> 0:32:41.600
<v Speaker 1>Maybe it means that you can't afford to buy healthier foods.

0:32:41.720 --> 0:32:44.320
<v Speaker 1>Maybe it means wearing sunscreen, maybe it means smoking. All

0:32:44.320 --> 0:32:48.280
<v Speaker 1>of these different things that are individually modifiable or potentially not.

0:32:49.280 --> 0:32:53.239
<v Speaker 1>It varies around the globe due to national policies, and

0:32:53.360 --> 0:32:55.800
<v Speaker 1>it varies on whether we have the technology to do

0:32:55.840 --> 0:32:59.360
<v Speaker 1>something about it. So, for instance, epstein bar virus EBV

0:32:59.840 --> 0:33:03.040
<v Speaker 1>is one of the most ubiquitous viruses. I've infected ninety

0:33:03.040 --> 0:33:05.360
<v Speaker 1>percent of adults. It's responsible for nearly three hundred and

0:33:05.400 --> 0:33:10.120
<v Speaker 1>sixty thousand cancers annually across the globe. Yet at the

0:33:10.120 --> 0:33:12.640
<v Speaker 1>time of writing, we do not have a vaccine for

0:33:12.680 --> 0:33:14.800
<v Speaker 1>this virus. We do have several in the works. Also,

0:33:15.080 --> 0:33:17.840
<v Speaker 1>EBV is thought to be linked to many other things

0:33:18.160 --> 0:33:23.320
<v Speaker 1>in our MSMs EBV. Yeah, but we do have a

0:33:23.400 --> 0:33:26.680
<v Speaker 1>vaccine for the hepatitis B virus we do, which can

0:33:26.760 --> 0:33:30.040
<v Speaker 1>lead to liver cancer, and human pepeloma virus HPV, which

0:33:30.080 --> 0:33:35.280
<v Speaker 1>can cause cervical other intogenital cancers and oropharyngeal cancers. It's

0:33:35.320 --> 0:33:37.160
<v Speaker 1>amazing that we have these these vaccines.

0:33:37.200 --> 0:33:38.560
<v Speaker 3>We can prevent cancers.

0:33:38.560 --> 0:33:42.080
<v Speaker 1>With vaccines, we can prevent some cancers. Yes, these are

0:33:42.120 --> 0:33:46.360
<v Speaker 1>incredible achievements that are projected to prevent millions of cases

0:33:46.360 --> 0:33:49.440
<v Speaker 1>of cancer over the next few decades. And as with

0:33:49.520 --> 0:33:53.800
<v Speaker 1>any success, there is room for improvement, you know, which

0:33:53.800 --> 0:33:57.960
<v Speaker 1>is understated. Hopefully we will see HEPB and HPV vaccine

0:33:58.040 --> 0:34:01.320
<v Speaker 1>uptake improve in their near future, include in policy changes

0:34:01.360 --> 0:34:03.880
<v Speaker 1>that will reverse some of the horrific decisions made by

0:34:04.000 --> 0:34:09.959
<v Speaker 1>this current head of HHS. But that is a major

0:34:10.000 --> 0:34:13.640
<v Speaker 1>concern here in the US. Like we will see reversal

0:34:13.680 --> 0:34:16.280
<v Speaker 1>in some of these trends, we will see cancer development

0:34:16.280 --> 0:34:20.520
<v Speaker 1>because people elect not to use these vaccines if they can. Yeah,

0:34:21.440 --> 0:34:26.279
<v Speaker 1>but before we had the HPV vaccine, we had ANHPV

0:34:26.360 --> 0:34:29.200
<v Speaker 1>testing I'll throw that in there. We also had another

0:34:29.280 --> 0:34:32.440
<v Speaker 1>powerful tool to reduce cancer deaths due to this virus.

0:34:32.680 --> 0:34:35.920
<v Speaker 1>We did the paps mares, the pap smear. We again

0:34:36.160 --> 0:34:39.360
<v Speaker 1>check out our episode. The pap smear was first developed

0:34:39.400 --> 0:34:43.000
<v Speaker 1>in nineteen twenty eight by Georgias Pepa Nicolau. He was

0:34:43.120 --> 0:34:45.719
<v Speaker 1>a physician and a scientist. He became interested in the

0:34:45.719 --> 0:34:51.000
<v Speaker 1>menstrual cycles of humans and especially cellular changes throughout the cycle,

0:34:51.080 --> 0:34:54.279
<v Speaker 1>like what's going on going on? What's happening Yeah, as

0:34:54.280 --> 0:34:57.480
<v Speaker 1>we go through this twenty eight through twenty five to

0:34:57.719 --> 0:35:01.799
<v Speaker 1>thirty seven days whatever this, Yeah, and he noticed that

0:35:01.840 --> 0:35:04.840
<v Speaker 1>he as he was like observing these cellular changes, he

0:35:04.880 --> 0:35:08.680
<v Speaker 1>saw that in certain samples the cells seemed oddly shaped,

0:35:10.200 --> 0:35:14.680
<v Speaker 1>kind of like they were cancerous maybe, And he realized like, oh,

0:35:14.719 --> 0:35:17.000
<v Speaker 1>I could use this test not just to like see

0:35:17.080 --> 0:35:21.759
<v Speaker 1>what's happening, but also to detect pre clinical, pre symptomatic

0:35:21.800 --> 0:35:26.040
<v Speaker 1>cases of cervical cancer. Wow. Amazing. And this was especially

0:35:26.040 --> 0:35:31.600
<v Speaker 1>important because like symptomatic usually, as we discussed, meansmetastasis often

0:35:31.800 --> 0:35:34.880
<v Speaker 1>and decreased or survival.

0:35:34.960 --> 0:35:37.680
<v Speaker 5>Yeah, like just invasive, Like the cervix is in such

0:35:37.680 --> 0:35:42.080
<v Speaker 5>a small area that it can go invasive, even just locally,

0:35:42.360 --> 0:35:43.840
<v Speaker 5>very quickly, very quickly.

0:35:43.920 --> 0:35:48.600
<v Speaker 1>So yeah, So detecting early means intervention early means higher

0:35:48.719 --> 0:35:53.960
<v Speaker 1>chance of increased survival. Yeah. His wife, Andromache was not

0:35:54.000 --> 0:35:56.640
<v Speaker 1>only worked alongside him at Cornell, but but was also

0:35:56.680 --> 0:35:59.839
<v Speaker 1>his research subject. She volunteered to undergo a daily perhaps

0:36:00.200 --> 0:36:05.200
<v Speaker 1>for two decades, two decades, twenty years.

0:36:05.000 --> 0:36:07.320
<v Speaker 3>Twenty years of everyday perap smears.

0:36:07.400 --> 0:36:07.680
<v Speaker 1>Yeah.

0:36:07.760 --> 0:36:09.000
<v Speaker 3>I don't have words for that.

0:36:09.080 --> 0:36:11.680
<v Speaker 1>I know, to help improve this test, what do normal

0:36:11.680 --> 0:36:13.520
<v Speaker 1>cells look like? What do cancer cells look like?

0:36:13.600 --> 0:36:14.879
<v Speaker 3>Yeah, oh, that's fascinating.

0:36:15.680 --> 0:36:16.000
<v Speaker 9>Wow.

0:36:16.280 --> 0:36:18.440
<v Speaker 1>And it took a few decades to catch on after

0:36:18.480 --> 0:36:21.080
<v Speaker 1>he formally introduced the pap smere in nineteen forty one,

0:36:21.160 --> 0:36:24.360
<v Speaker 1>but since being adopted as a routine screening tool, it

0:36:24.400 --> 0:36:28.319
<v Speaker 1>has led to early diagnosis and treatment intervention for untold

0:36:28.360 --> 0:36:29.480
<v Speaker 1>amounts of people around the world.

0:36:29.600 --> 0:36:32.359
<v Speaker 3>Yeah, it really is. The papspeers incredible.

0:36:32.080 --> 0:36:33.600
<v Speaker 1>Perhaps means pretty great.

0:36:33.640 --> 0:36:34.040
<v Speaker 3>Yeah.

0:36:34.239 --> 0:36:37.000
<v Speaker 1>So the papsmere falls under the category of cancer screening

0:36:37.320 --> 0:36:41.640
<v Speaker 1>using early detection methods to improve treatment outcomes. The intention

0:36:41.800 --> 0:36:45.080
<v Speaker 1>of cancer screening is not necessarily total prevention, but being

0:36:45.120 --> 0:36:48.800
<v Speaker 1>able to intervene as early as possible. We have ways

0:36:48.800 --> 0:36:53.360
<v Speaker 1>to screen for cervical, breast, colon, lung, prostate, skin, other cancers.

0:36:53.400 --> 0:36:57.040
<v Speaker 1>Some screenings involve imaging, like with a colonoscopy. They might

0:36:57.080 --> 0:36:59.680
<v Speaker 1>involve a blood test like the prostate specific antigen or

0:36:59.680 --> 0:37:02.560
<v Speaker 1>PUS say blood test, or it might be a visual

0:37:02.640 --> 0:37:07.240
<v Speaker 1>or physical exam. For skin cancer, for instance, screening methods

0:37:07.320 --> 0:37:09.399
<v Speaker 1>might be combined. You might do a couple of them.

0:37:09.440 --> 0:37:12.440
<v Speaker 1>You might have step one, step two yep. And while

0:37:12.440 --> 0:37:15.279
<v Speaker 1>there are general guidelines for when to screen, what to

0:37:15.320 --> 0:37:19.000
<v Speaker 1>screen for, and how often, you screen. These might vary

0:37:19.040 --> 0:37:21.840
<v Speaker 1>depending on other factors, like if, for instance, you have

0:37:21.880 --> 0:37:24.640
<v Speaker 1>a family history of cancer, your doctor might recommend you

0:37:24.680 --> 0:37:27.799
<v Speaker 1>get screened earlier and more frequently. Some people might get

0:37:27.800 --> 0:37:30.160
<v Speaker 1>genetic testing done to see if they are at higher risk,

0:37:30.200 --> 0:37:33.840
<v Speaker 1>which could then influence care decisions. We'll talk more about that.

0:37:35.080 --> 0:37:39.360
<v Speaker 1>On the surface, screening seems fairly straightforward. The earlier you

0:37:39.400 --> 0:37:41.920
<v Speaker 1>detect cancer, the greater the chance that you have of

0:37:41.960 --> 0:37:46.160
<v Speaker 1>successfully treating it. But you're listening to this podcast, so

0:37:46.200 --> 0:37:48.120
<v Speaker 1>we know that you're not here for the surface level. No,

0:37:49.560 --> 0:37:55.359
<v Speaker 1>early conceptualization of screening assumed that cancer progresses linearly, that

0:37:55.400 --> 0:37:58.160
<v Speaker 1>the earlier you detect cancer and treat it, the smaller

0:37:58.200 --> 0:38:00.759
<v Speaker 1>the tumor the means that this is more contained, the

0:38:00.840 --> 0:38:05.120
<v Speaker 1>better the chance for survival. That is the case for

0:38:05.239 --> 0:38:09.239
<v Speaker 1>certain cancers or for certain cases individual cases, But it's

0:38:09.360 --> 0:38:12.960
<v Speaker 1>not always the case. While some cancers might be localized

0:38:13.000 --> 0:38:15.800
<v Speaker 1>and it might grow slowly, others may have already spread

0:38:15.840 --> 0:38:18.600
<v Speaker 1>at the time of detection, and so the benefit of

0:38:18.680 --> 0:38:22.200
<v Speaker 1>early treatment might not be there. It might not be

0:38:22.560 --> 0:38:24.760
<v Speaker 1>like that the earlier you catch it, the better the chance.

0:38:25.560 --> 0:38:30.240
<v Speaker 1>It's not as clear as that screening, so I guess.

0:38:30.600 --> 0:38:33.160
<v Speaker 1>In other words, early detection does not always equate to

0:38:33.200 --> 0:38:38.200
<v Speaker 1>better survival, right, Yeah, Yeah, screening might also lead to

0:38:38.280 --> 0:38:42.799
<v Speaker 1>false positives or false negatives. Screening is not diagnostic, but

0:38:43.000 --> 0:38:45.600
<v Speaker 1>your results could be abnormal, which means you need to

0:38:45.640 --> 0:38:48.200
<v Speaker 1>go get further testing. And then so that could mean

0:38:48.239 --> 0:38:51.280
<v Speaker 1>that if you have abnormal results when you don't have cancer,

0:38:51.360 --> 0:38:53.440
<v Speaker 1>that means that you're about to undergo a bunch of

0:38:53.440 --> 0:38:56.279
<v Speaker 1>additional tests, which can be expensive, it can be really distressing,

0:38:56.440 --> 0:38:59.959
<v Speaker 1>it can be invasive, there are side effects to those,

0:39:01.000 --> 0:39:02.759
<v Speaker 1>so that those are some of the risks of a

0:39:02.840 --> 0:39:06.279
<v Speaker 1>false positive. And then of course there's false negatives, which

0:39:06.320 --> 0:39:09.880
<v Speaker 1>means that your results from screening show no signs of

0:39:10.000 --> 0:39:13.360
<v Speaker 1>potential for cancer, you don't get additional testing, but you

0:39:13.400 --> 0:39:18.120
<v Speaker 1>do have we miss something. Yeah. These are risks that

0:39:18.160 --> 0:39:22.040
<v Speaker 1>happen with any medical test, and it's especially important to

0:39:22.160 --> 0:39:25.520
<v Speaker 1>minimize the rate of false negatives missing something, and that

0:39:25.760 --> 0:39:30.279
<v Speaker 1>sometimes comes at the cost of increasing false positives. A

0:39:30.320 --> 0:39:33.799
<v Speaker 1>false negative means missing someone's potentially treatable cancer, which could

0:39:33.840 --> 0:39:36.920
<v Speaker 1>cost them their life, and a false positive means unnecessary

0:39:37.040 --> 0:39:40.759
<v Speaker 1>additional testing that can be time consuming, expensive and distressing.

0:39:41.080 --> 0:39:43.799
<v Speaker 1>So all this is to say again that it just

0:39:43.800 --> 0:39:45.440
<v Speaker 1>comes down to the same thing. On a case by

0:39:45.480 --> 0:39:49.440
<v Speaker 1>case basis, the benefits of screening might not always outweigh

0:39:49.480 --> 0:39:53.960
<v Speaker 1>the cons, but it's so hard to know that upfront.

0:39:54.080 --> 0:39:54.319
<v Speaker 3>Yep.

0:39:56.480 --> 0:40:00.799
<v Speaker 1>And that being said, you know, early detection does not

0:40:00.800 --> 0:40:04.080
<v Speaker 1>always equate to longer survival, but often it does.

0:40:04.200 --> 0:40:04.839
<v Speaker 3>Often it does.

0:40:05.000 --> 0:40:07.880
<v Speaker 1>Often it does. And the fact that screening doesn't eliminate

0:40:07.920 --> 0:40:11.120
<v Speaker 1>the risk of dying from cancer entirely does not mean

0:40:11.280 --> 0:40:15.719
<v Speaker 1>that physicians are out here recommending these screening tests willy nilly, right, go,

0:40:16.320 --> 0:40:21.400
<v Speaker 1>oh yeah, they're not like, oh, I better better cover myself.

0:40:21.440 --> 0:40:23.120
<v Speaker 1>So let's get you screen for this, that and the

0:40:23.200 --> 0:40:27.400
<v Speaker 1>other thing. It is, there decades of data to support

0:40:27.400 --> 0:40:30.880
<v Speaker 1>this there, and there are important guidelines that must be

0:40:30.920 --> 0:40:33.719
<v Speaker 1>followed before a screening test is incorporated into standard care.

0:40:33.920 --> 0:40:36.319
<v Speaker 1>If you listen to our Newborn screening episode, this might

0:40:36.360 --> 0:40:38.440
<v Speaker 1>sound a bit familiar to you. So in the late

0:40:38.520 --> 0:40:40.359
<v Speaker 1>nineteen sixties, I'm going to repeat it here.

0:40:40.440 --> 0:40:42.200
<v Speaker 3>I love it. I love it.

0:40:42.200 --> 0:40:45.160
<v Speaker 1>It's a good refresher. I feel like it's like because

0:40:45.400 --> 0:40:48.200
<v Speaker 1>I think there's been a lot of Again, it kind

0:40:48.239 --> 0:40:50.840
<v Speaker 1>of comes down to public health being invisible until.

0:40:50.640 --> 0:40:52.600
<v Speaker 3>It until it fails until it fails.

0:40:52.640 --> 0:40:55.120
<v Speaker 1>And it's like screening is. And I'm not saying screening

0:40:55.160 --> 0:41:00.440
<v Speaker 1>is always positive, no, but I think sometimes the benefits

0:41:00.480 --> 0:41:04.040
<v Speaker 1>of screening are get drowned out by the very real

0:41:04.080 --> 0:41:04.640
<v Speaker 1>cons that.

0:41:04.640 --> 0:41:09.680
<v Speaker 5>Exist or the limitation, mystery diagnoses or whatever it is.

0:41:10.280 --> 0:41:12.080
<v Speaker 5>You know, like, is mammogram perfect?

0:41:12.200 --> 0:41:12.359
<v Speaker 9>No?

0:41:12.520 --> 0:41:14.120
<v Speaker 3>But has it saved so many lives?

0:41:14.239 --> 0:41:14.439
<v Speaker 5>Yes?

0:41:14.640 --> 0:41:14.759
<v Speaker 2>Right?

0:41:14.920 --> 0:41:19.200
<v Speaker 1>Is a colonoscopy prep very challenging and very uncomfortable? Yes?

0:41:19.280 --> 0:41:19.480
<v Speaker 9>Yeah?

0:41:19.560 --> 0:41:20.600
<v Speaker 3>Could it save your life?

0:41:20.640 --> 0:41:21.480
<v Speaker 1>Also? Yes?

0:41:22.040 --> 0:41:24.600
<v Speaker 3>Does everyone need it? Maybe not? Are there other ways

0:41:24.600 --> 0:41:27.239
<v Speaker 3>we'll talk about talk about it, but tell me about yes?

0:41:27.320 --> 0:41:31.239
<v Speaker 1>The guidelines so okay. Quarineteen sixties the who published the

0:41:31.280 --> 0:41:33.960
<v Speaker 1>Principles and Practice of Screening for Disease, also known as

0:41:34.000 --> 0:41:37.680
<v Speaker 1>the Wilson and Younger or Younger Screening Criteria, which outline

0:41:37.840 --> 0:41:40.880
<v Speaker 1>ten rules that a screening test should follow, things like

0:41:40.920 --> 0:41:43.239
<v Speaker 1>I'm not going to list them all here, but it's

0:41:43.280 --> 0:41:46.000
<v Speaker 1>things like the test should be reliable and not harmful.

0:41:46.160 --> 0:41:48.960
<v Speaker 1>There should be an effective treatment, and that treatment has

0:41:49.000 --> 0:41:52.840
<v Speaker 1>been demonstrated to be more effective before symptoms. That's really important,

0:41:52.880 --> 0:41:55.759
<v Speaker 1>really important. And there should be a standard policy for

0:41:55.840 --> 0:41:59.720
<v Speaker 1>treatment and who receives treatment in the nearly sixty years

0:41:59.760 --> 0:42:04.280
<v Speaker 1>sin these criteria were introduced, Biomedical technology has undergone a revolution,

0:42:04.600 --> 0:42:07.720
<v Speaker 1>and we can know more about ourselves than ever before.

0:42:08.360 --> 0:42:11.000
<v Speaker 1>And as we all know, technology moves too quickly for

0:42:11.120 --> 0:42:14.600
<v Speaker 1>us to anticipate the full extent of its impact. These

0:42:14.640 --> 0:42:17.560
<v Speaker 1>principles for screening, whether they are adjusted or not, will

0:42:17.600 --> 0:42:21.359
<v Speaker 1>be foundational in continuing to minimize harm as much as

0:42:21.440 --> 0:42:25.960
<v Speaker 1>possible as new screening is introduced. Yeah, Like, I really

0:42:25.960 --> 0:42:28.400
<v Speaker 1>don't want to give the impression that screening does not work,

0:42:28.800 --> 0:42:32.560
<v Speaker 1>or even imply that screening is perfect. I simply want

0:42:32.560 --> 0:42:34.719
<v Speaker 1>to convey that the reality, as is often the case,

0:42:34.800 --> 0:42:37.239
<v Speaker 1>is more complicated than that, because I.

0:42:37.160 --> 0:42:39.360
<v Speaker 5>Mean there's also maybe you're going to talk about this,

0:42:39.440 --> 0:42:41.879
<v Speaker 5>I don't like, jump on your feet.

0:42:41.719 --> 0:42:45.279
<v Speaker 1>I think step on my feet, whatever, jump on the.

0:42:45.680 --> 0:42:48.239
<v Speaker 5>But there's also like sometimes you know, you said that

0:42:48.360 --> 0:42:51.120
<v Speaker 5>maybe screening won't necessarily prolong your life if we can

0:42:51.160 --> 0:42:54.080
<v Speaker 5>detect it early. Sometimes we can also detect cancers that

0:42:54.200 --> 0:42:57.120
<v Speaker 5>might have never really come to anything. Yes, right, And

0:42:57.160 --> 0:42:59.719
<v Speaker 5>so then we give this impression that we are improving

0:42:59.760 --> 0:43:02.960
<v Speaker 5>out comes when maybe we aren't. We're just you know,

0:43:03.080 --> 0:43:07.040
<v Speaker 5>increasing how many case cancer cases we're detecting so yeah,

0:43:07.040 --> 0:43:09.360
<v Speaker 5>there's a lot of complicated things that come with screening,

0:43:09.360 --> 0:43:12.319
<v Speaker 5>which is why there's so many, you know, guidelines and

0:43:12.360 --> 0:43:15.279
<v Speaker 5>decisions and data that has to go into deciding how

0:43:15.320 --> 0:43:18.000
<v Speaker 5>to recommend screening and who to recommend screening for, like

0:43:18.080 --> 0:43:19.720
<v Speaker 5>what populations.

0:43:19.120 --> 0:43:22.200
<v Speaker 1>Right right, And it's like the thing too, is that

0:43:22.760 --> 0:43:25.799
<v Speaker 1>there is one road, right, like for one person, there

0:43:25.880 --> 0:43:28.120
<v Speaker 1>is one road, one suite of decisions that get you

0:43:28.160 --> 0:43:30.680
<v Speaker 1>to where you are. And so you can't know what

0:43:30.960 --> 0:43:34.320
<v Speaker 1>screening have done. This would if I if I hadn't

0:43:34.320 --> 0:43:36.120
<v Speaker 1>gotten screening, would that have been better? You know, like,

0:43:36.640 --> 0:43:39.239
<v Speaker 1>you just can't know these things, and so we do

0:43:39.280 --> 0:43:41.120
<v Speaker 1>the best we can with the available data that we

0:43:41.160 --> 0:43:47.080
<v Speaker 1>have with cancer screening, prevention, and treatment. We have the

0:43:47.120 --> 0:43:49.920
<v Speaker 1>tools and the information to bring down those forty percent

0:43:49.960 --> 0:43:52.480
<v Speaker 1>and seventeen percent numbers I mentioned at the top, So

0:43:52.600 --> 0:43:55.680
<v Speaker 1>forty percent lifetime risk of cancer, seventeen percent chance of

0:43:55.760 --> 0:44:01.040
<v Speaker 1>dying from cancer, but having this knowledge does not guarantee

0:44:01.040 --> 0:44:06.320
<v Speaker 1>a decreased global cancer burden by any means. Throughout this series,

0:44:06.400 --> 0:44:10.120
<v Speaker 1>we've discussed some reasons why government and action, even when

0:44:10.120 --> 0:44:15.640
<v Speaker 1>faced with overwhelming evidence cases where screening can't improve survival.

0:44:16.239 --> 0:44:20.920
<v Speaker 1>The biology of cancer itself. Lifestyle factors increase in cancer risk,

0:44:21.360 --> 0:44:26.480
<v Speaker 1>genetic predisposition to cancer. And there's another enormous aspect that

0:44:26.600 --> 0:44:31.600
<v Speaker 1>you touched on briefly last episode, and that is access, yes,

0:44:32.040 --> 0:44:35.440
<v Speaker 1>both to knowledge as well as care, which includes screening

0:44:35.440 --> 0:44:39.080
<v Speaker 1>and treatment. In the US as well as across the globe,

0:44:39.120 --> 0:44:43.560
<v Speaker 1>substantial cancer disparities exist in terms of diagnosis and survival.

0:44:44.040 --> 0:44:46.480
<v Speaker 1>You talked a little bit last week, and individual's experience

0:44:46.480 --> 0:44:50.959
<v Speaker 1>with cancer is influenced by race, ethnicity, socioeconomic status, education level,

0:44:51.320 --> 0:44:55.040
<v Speaker 1>so many different things. So, for instance, black women in

0:44:55.080 --> 0:44:58.160
<v Speaker 1>the US diagnosed with cancer have a ten percent higher

0:44:58.239 --> 0:45:01.320
<v Speaker 1>death rate compared to white women having a nine percent

0:45:01.440 --> 0:45:06.560
<v Speaker 1>lower incidence rate. Wow, education levels also associated with cancer mortality.

0:45:06.719 --> 0:45:10.160
<v Speaker 1>Lung cancer mortality is four to five times higher in

0:45:10.239 --> 0:45:12.960
<v Speaker 1>those with the lowest education level compared to those with

0:45:13.000 --> 0:45:17.640
<v Speaker 1>the highest. Geography, often tied to income, also plays a role,

0:45:17.840 --> 0:45:20.920
<v Speaker 1>with those who are in more rural or poverty stricken

0:45:20.960 --> 0:45:26.359
<v Speaker 1>areas experiencing higher cancer death rates. These disparities, and you're

0:45:26.360 --> 0:45:28.520
<v Speaker 1>going to talk more about them in the numbers. Yeah,

0:45:28.800 --> 0:45:33.000
<v Speaker 1>they represent long standing structural inequalities that lead to higher

0:45:33.120 --> 0:45:35.319
<v Speaker 1>rates of preventable morbidity.

0:45:35.360 --> 0:45:36.920
<v Speaker 3>And mortality.

0:45:37.680 --> 0:45:40.759
<v Speaker 1>What good are cutting edge treatments to you if you

0:45:40.840 --> 0:45:44.200
<v Speaker 1>don't have access to them. What good are screening tests

0:45:44.239 --> 0:45:46.839
<v Speaker 1>to you if you can't afford them because you can't

0:45:46.840 --> 0:45:47.760
<v Speaker 1>afford health insurance?

0:45:47.800 --> 0:45:48.040
<v Speaker 5>Yep?

0:45:48.800 --> 0:45:51.640
<v Speaker 1>What good are awareness campaigns if they never make it

0:45:51.680 --> 0:45:55.640
<v Speaker 1>to your door. We have spent the last four episodes

0:45:55.719 --> 0:46:00.880
<v Speaker 1>dissecting cancer, deciphering its many meanings, exploring its biology, understanding

0:46:00.920 --> 0:46:04.319
<v Speaker 1>its treatments, and describing prevention and screening methods. It is

0:46:04.960 --> 0:46:08.880
<v Speaker 1>a wealth of information, but in this country and around

0:46:08.920 --> 0:46:13.160
<v Speaker 1>the world, we are not adequately leveraging this information for

0:46:13.280 --> 0:46:14.880
<v Speaker 1>everyone to benefit equally.

0:46:15.000 --> 0:46:15.239
<v Speaker 3>Yep.

0:46:16.000 --> 0:46:18.120
<v Speaker 1>This is not a problem that will be solved through

0:46:18.200 --> 0:46:22.319
<v Speaker 1>cutting edge technology, but through better access, better education, more

0:46:22.360 --> 0:46:26.920
<v Speaker 1>affordable healthcare, and a willingness to scrutinize and dismantle the

0:46:26.960 --> 0:46:31.080
<v Speaker 1>structural inequalities and systemic racism that drive these health disparities

0:46:31.120 --> 0:46:35.839
<v Speaker 1>on Yep. Yep. Not all parts of cancer are within

0:46:35.920 --> 0:46:39.560
<v Speaker 1>our control, but some are both. At an individual level,

0:46:39.760 --> 0:46:43.520
<v Speaker 1>we can make individual changes and societal we can make

0:46:43.560 --> 0:46:44.600
<v Speaker 1>societal changes.

0:46:44.640 --> 0:46:46.320
<v Speaker 5>I think that's the biggest one, because I think people

0:46:46.360 --> 0:46:49.439
<v Speaker 5>only like to focus on the individual level, like, oh,

0:46:49.520 --> 0:46:51.800
<v Speaker 5>you should be doing X, Y and Z. What about

0:46:51.880 --> 0:46:54.799
<v Speaker 5>we should all what about we should our country should be?

0:46:54.880 --> 0:46:57.359
<v Speaker 5>What about our global community should be?

0:46:57.600 --> 0:46:57.799
<v Speaker 2>Right?

0:46:58.040 --> 0:47:01.960
<v Speaker 1>Yeah, and so choose what we do with all of

0:47:01.960 --> 0:47:05.600
<v Speaker 1>this information. It is a personal it is a political,

0:47:05.640 --> 0:47:08.320
<v Speaker 1>it is a medical, and it is a philosophical matter.

0:47:09.120 --> 0:47:11.040
<v Speaker 1>And with that, Aeron, I'll turn it over to you

0:47:11.080 --> 0:47:14.040
<v Speaker 1>to tell me that the status of cancer around the

0:47:14.080 --> 0:47:16.120
<v Speaker 1>world today. That's not a big ass no, right, not

0:47:16.200 --> 0:47:21.360
<v Speaker 1>at all, guys. Small potatoes, erin, super small, the tiniest potatoes,

0:47:21.400 --> 0:47:22.760
<v Speaker 1>baby potatoes, new potatoes.

0:47:22.800 --> 0:47:27.040
<v Speaker 5>Oh, Aaron, it's dark, yeah, yeah, yeah, Okay, no, I

0:47:27.080 --> 0:47:30.080
<v Speaker 5>know we're going to go down. It's going to be

0:47:30.160 --> 0:47:33.000
<v Speaker 5>dark for a moment, but hopefully I think there is

0:47:33.040 --> 0:47:34.440
<v Speaker 5>some bright futures on the horizon.

0:47:34.560 --> 0:47:49.240
<v Speaker 8>Okay, okay.

0:47:49.520 --> 0:47:51.200
<v Speaker 10>My name is Sam and about four and a half

0:47:51.200 --> 0:47:53.440
<v Speaker 10>months ago, at the age of thirty five, I was

0:47:53.480 --> 0:47:57.200
<v Speaker 10>diagnosed with stage one triple negative breast cancer. My cancer

0:47:57.280 --> 0:48:00.880
<v Speaker 10>journey began unexpectedly out of curiosity. I had enrolled in

0:48:00.920 --> 0:48:03.320
<v Speaker 10>a research study that identified I have a BRAC of

0:48:03.360 --> 0:48:07.640
<v Speaker 10>one mutation. This mutation affects DNA repair and increases the

0:48:07.680 --> 0:48:10.320
<v Speaker 10>risk of various types of cancer, most notably breast and

0:48:10.360 --> 0:48:15.759
<v Speaker 10>Ovriian cancer. That finding triggered additional screenings, including mammograms, ultrasounds,

0:48:15.760 --> 0:48:19.440
<v Speaker 10>and ultimately a biopsy that led to my diagnosis. It

0:48:19.440 --> 0:48:21.640
<v Speaker 10>feels strange to say I'm lucky to have been diagnosed

0:48:21.640 --> 0:48:23.919
<v Speaker 10>with an aggressive form of cancer, but at the time

0:48:23.960 --> 0:48:26.879
<v Speaker 10>of my diagnosis, I truly had no symptoms, no known

0:48:26.920 --> 0:48:29.920
<v Speaker 10>family history, and I wasn't scheduled to begin routine screenings

0:48:29.920 --> 0:48:32.719
<v Speaker 10>for another five years. So in that sense, I am

0:48:32.760 --> 0:48:35.279
<v Speaker 10>incredibly fortunate that my cancer was still caught early at

0:48:35.280 --> 0:48:39.480
<v Speaker 10>stage one. My treatment plan includes chemotherapy followed by a

0:48:39.480 --> 0:48:42.560
<v Speaker 10>double mestectomy. At the time of this recording, I have

0:48:42.640 --> 0:48:46.600
<v Speaker 10>completed sixteen out of eighteen weeks of chemo. Overall, chemo

0:48:46.680 --> 0:48:49.080
<v Speaker 10>hasn't been as bad as I expected, but it hasn't

0:48:49.080 --> 0:48:53.440
<v Speaker 10>been easy either. The main challenges for me have been anemia, fatigue,

0:48:53.680 --> 0:48:56.440
<v Speaker 10>and some peripheral neuropathy or a loss of sensation in

0:48:56.480 --> 0:49:00.279
<v Speaker 10>my fingers. The side effects build over time. The first

0:49:00.280 --> 0:49:02.759
<v Speaker 10>couple of months were manageable. The side effects are absolutely

0:49:02.800 --> 0:49:05.120
<v Speaker 10>wearing on me, and I am so ready to be done.

0:49:05.600 --> 0:49:08.520
<v Speaker 10>That said, the hardest part of this experience so far

0:49:08.640 --> 0:49:11.920
<v Speaker 10>hasn't been the chemotherapy. For me, it was actually the

0:49:11.920 --> 0:49:15.400
<v Speaker 10>period between diagnosis and starting treatment. During that time, my

0:49:15.440 --> 0:49:18.480
<v Speaker 10>treatment plan changed multiple times, and I was navigating the

0:49:18.520 --> 0:49:21.399
<v Speaker 10>fear and uncertainty of a cancer diagnosis while still working

0:49:21.440 --> 0:49:23.879
<v Speaker 10>full time and managing a whole host of other logistics

0:49:24.320 --> 0:49:28.279
<v Speaker 10>scheduling second opinions, vaccinations, dentist appointments, all before I had

0:49:28.280 --> 0:49:30.600
<v Speaker 10>told most of my friends and family about my diagnosis.

0:49:31.920 --> 0:49:34.600
<v Speaker 10>Another unexpected challenge has been grieving the loss of my

0:49:34.640 --> 0:49:38.480
<v Speaker 10>former identity as a healthy, fit person. Even knowing that

0:49:38.520 --> 0:49:41.640
<v Speaker 10>most side effects of chemotherapy are temporary, I still really

0:49:41.640 --> 0:49:44.200
<v Speaker 10>miss being someone who didn't need to memorize medication lists

0:49:44.200 --> 0:49:48.480
<v Speaker 10>in doctor's visits or think twice about physical limits. At

0:49:48.480 --> 0:49:51.000
<v Speaker 10>this point, I'm still very much in this journey. After

0:49:51.000 --> 0:49:54.520
<v Speaker 10>my current chemotherapy regimen, I'll have surgery, potentially followed by

0:49:54.520 --> 0:49:58.680
<v Speaker 10>another year of oral chemotherapy along with additional prophylactic surgeries

0:49:58.760 --> 0:50:02.400
<v Speaker 10>due to my braco one mutation. Ultimately, I'm still learning

0:50:02.400 --> 0:50:05.280
<v Speaker 10>how to live with uncertainty, how to advocate for myself,

0:50:05.480 --> 0:50:07.760
<v Speaker 10>and how to redefine who I am while moving forward

0:50:07.760 --> 0:50:08.799
<v Speaker 10>from this diagnosis.

0:50:10.520 --> 0:50:13.160
<v Speaker 9>Hello, my name is Karen. I'm here to tell you

0:50:13.200 --> 0:50:16.400
<v Speaker 9>about some of the barriers and frustrations my family have

0:50:16.560 --> 0:50:20.399
<v Speaker 9>had since our adult son was diagnosed with stage four

0:50:20.680 --> 0:50:27.000
<v Speaker 9>metastatic medullary thyroid cancer or MTC, four years ago. In

0:50:27.040 --> 0:50:30.280
<v Speaker 9>case you are unaware, there are several types of thyroid cancer.

0:50:30.680 --> 0:50:34.000
<v Speaker 9>Some are very common and not aggressive at all, and

0:50:34.080 --> 0:50:38.920
<v Speaker 9>some are rare and aggressive. Unfortunately, MTC is the latter.

0:50:39.719 --> 0:50:42.399
<v Speaker 9>Only about one thousand people in the United States are

0:50:42.400 --> 0:50:46.319
<v Speaker 9>diagnosed with it each year. As such, research dollars are

0:50:46.360 --> 0:50:50.520
<v Speaker 9>few and far between for such rare cancers, and therefore

0:50:50.800 --> 0:50:55.399
<v Speaker 9>treatments are limited and few and rare. Cancer specialists are

0:50:55.480 --> 0:50:59.600
<v Speaker 9>also rare and not typically in network for insurance companies.

0:50:59.640 --> 0:51:04.120
<v Speaker 9>To additional frustrations and barriers to treatment because of the

0:51:04.239 --> 0:51:09.600
<v Speaker 9>rarity of his cancer have been centered around multiple insurance denials.

0:51:10.360 --> 0:51:14.919
<v Speaker 9>Some of these denials are for recommended treatments. I took

0:51:14.920 --> 0:51:19.719
<v Speaker 9>over writing appeals as I have a medical background. I

0:51:19.800 --> 0:51:23.440
<v Speaker 9>was thorough in my research, and in one case, ultimately,

0:51:23.520 --> 0:51:27.680
<v Speaker 9>after three appeals for a type of radiation treatment that's

0:51:27.760 --> 0:51:31.600
<v Speaker 9>recommended for MTC, was finally able to get the approval

0:51:31.680 --> 0:51:34.960
<v Speaker 9>for it for our son. However, at one point the

0:51:34.960 --> 0:51:40.160
<v Speaker 9>insurance companies oncologists wrote to me and stated, what does

0:51:40.200 --> 0:51:44.919
<v Speaker 9>it matter as he's going to die anyway, you can bet.

0:51:44.960 --> 0:51:48.040
<v Speaker 9>I reported her to the insurance company president and our

0:51:48.080 --> 0:51:52.360
<v Speaker 9>state insurance commissioner. The lack of compassion and the delays

0:51:52.640 --> 0:51:56.120
<v Speaker 9>in treatment because of denials and people like this are abhorrent.

0:51:56.719 --> 0:52:00.120
<v Speaker 9>This is just one but terrible example when as as

0:52:00.120 --> 0:52:02.280
<v Speaker 9>a family member, you are trying to do your best

0:52:02.320 --> 0:52:05.680
<v Speaker 9>to cope with and fight for your family member with

0:52:05.760 --> 0:52:10.239
<v Speaker 9>such a terrible disease. It is the red tape, the denials,

0:52:10.360 --> 0:52:14.680
<v Speaker 9>the appeals, and more denials leading to extreme out of

0:52:14.719 --> 0:52:20.080
<v Speaker 9>pocket expenses that I'm also reporting here. One medication is

0:52:20.200 --> 0:52:24.279
<v Speaker 9>thirty thousand dollars a month out of pocket because of

0:52:24.400 --> 0:52:29.359
<v Speaker 9>insurance denials. No one can sustain out of pocket expenses

0:52:29.480 --> 0:52:33.880
<v Speaker 9>like that. No one fighting any disease like MTC should

0:52:33.920 --> 0:52:38.360
<v Speaker 9>have to be subjected to such callousness delays and costs

0:52:38.360 --> 0:52:41.799
<v Speaker 9>and treatment. I can only sympathize with families who have

0:52:41.880 --> 0:52:44.719
<v Speaker 9>no one with a medical background to help them navigate

0:52:44.800 --> 0:52:48.600
<v Speaker 9>these barriers to treatment. It's difficult enough to fight cancer.

0:52:49.160 --> 0:52:51.520
<v Speaker 9>No one in this position should have to fight their

0:52:51.520 --> 0:52:56.480
<v Speaker 9>insurance companies to or go bankrupt to receive treatment. Thank you.

0:53:21.280 --> 0:53:24.000
<v Speaker 5>In twenty twenty three, which is the most recent global

0:53:24.040 --> 0:53:27.720
<v Speaker 5>data that I could find. Eighteen and a half million

0:53:27.760 --> 0:53:33.040
<v Speaker 5>people worldwide were newly diagnosed with cancer. That same year,

0:53:33.560 --> 0:53:40.160
<v Speaker 5>cancer killed over ten million people worldwide and contributed to

0:53:40.360 --> 0:53:45.600
<v Speaker 5>two hundred seventy one million disability adjusted life years.

0:53:46.880 --> 0:53:50.279
<v Speaker 1>I can't it's you can't even wrap your head around.

0:53:50.280 --> 0:53:51.320
<v Speaker 3>It's massive.

0:53:52.400 --> 0:53:56.760
<v Speaker 5>Over half of these cases and deaths were in low

0:53:56.800 --> 0:53:59.640
<v Speaker 5>and middle income countries. And I really think that we,

0:53:59.719 --> 0:54:02.799
<v Speaker 5>and I include myself in this royal, we do not

0:54:02.960 --> 0:54:05.800
<v Speaker 5>talk enough about cancer in low and middle income countries.

0:54:05.840 --> 0:54:07.160
<v Speaker 1>Oh yeah, absolutely not at all.

0:54:07.560 --> 0:54:09.480
<v Speaker 5>A lot of the data and the statistics that I

0:54:09.560 --> 0:54:11.440
<v Speaker 5>have and that we've talked about through this series are

0:54:11.480 --> 0:54:14.399
<v Speaker 5>from the US and from other high income countries where

0:54:14.400 --> 0:54:17.120
<v Speaker 5>cancer is not treated the same way as it is

0:54:17.200 --> 0:54:20.120
<v Speaker 5>in places with less resources, and of course in a

0:54:20.120 --> 0:54:22.120
<v Speaker 5>lot of parts of the US, things are pretty bleak

0:54:22.200 --> 0:54:24.160
<v Speaker 5>depending on who you are and where you live and

0:54:24.160 --> 0:54:28.840
<v Speaker 5>what you have access to. These numbers are also projected

0:54:28.840 --> 0:54:33.120
<v Speaker 5>to increase, not decrease. By twenty fifty, it's estimated that

0:54:33.160 --> 0:54:35.960
<v Speaker 5>we'll be looking at over thirty million new cases of

0:54:36.000 --> 0:54:41.040
<v Speaker 5>cancer every year and over eighteen million deaths globally. Cancer

0:54:41.200 --> 0:54:45.200
<v Speaker 5>is the second leading cause of death after cardiovascular disease,

0:54:45.680 --> 0:54:47.719
<v Speaker 5>which is such a contrast to what you said Aarin

0:54:47.760 --> 0:54:49.120
<v Speaker 5>in our very first episode that.

0:54:49.760 --> 0:54:52.279
<v Speaker 1>Hundreds of years ago, it was like nineteen hundred.

0:54:52.360 --> 0:54:54.239
<v Speaker 3>Oh nice, I.

0:54:54.120 --> 0:54:58.280
<v Speaker 5>Can't remember the eighth leading So that's a huge change, right,

0:54:58.320 --> 0:55:02.280
<v Speaker 5>And it's really partly due to all of the incredible

0:55:02.280 --> 0:55:04.680
<v Speaker 5>innovations that we've had in treating other causes of death

0:55:04.800 --> 0:55:06.400
<v Speaker 5>like infectious disease and things like that.

0:55:06.480 --> 0:55:08.680
<v Speaker 1>Yeah, yeah, yeah, longevity overall, et cetera.

0:55:08.719 --> 0:55:10.680
<v Speaker 3>Exactly many things, many many things.

0:55:10.760 --> 0:55:14.200
<v Speaker 5>All of these things can be true at once if

0:55:14.200 --> 0:55:15.880
<v Speaker 5>we look at the US specifically, I do have a

0:55:15.920 --> 0:55:19.560
<v Speaker 5>lot more data on the US. As of twenty twenty two,

0:55:20.200 --> 0:55:23.360
<v Speaker 5>there were an estimated eighteen million people living in the

0:55:23.480 --> 0:55:27.040
<v Speaker 5>US with cancer. Wow, which is about five five to

0:55:27.160 --> 0:55:30.480
<v Speaker 5>six percent of the US population currently living with cancer.

0:55:31.760 --> 0:55:33.160
<v Speaker 5>And as far as I can tell, that's like a

0:55:33.560 --> 0:55:36.839
<v Speaker 5>no a known diagnosis of cancer. And all of these

0:55:36.880 --> 0:55:41.400
<v Speaker 5>statistics do not include basal and sclamos cell carcinoma of

0:55:41.440 --> 0:55:43.200
<v Speaker 5>the skin, which is really important.

0:55:42.960 --> 0:55:44.239
<v Speaker 1>Is something that we haven't talked about.

0:55:44.320 --> 0:55:49.080
<v Speaker 5>Yeah, lifetime risks all of these millions of people numbers

0:55:49.280 --> 0:55:51.799
<v Speaker 5>that doesn't include those. Yeah, it does not include what's

0:55:51.800 --> 0:55:53.400
<v Speaker 5>called non melanoma skin cancer.

0:55:54.360 --> 0:55:56.880
<v Speaker 1>So that does the numbers become scarier?

0:55:56.920 --> 0:56:01.080
<v Speaker 5>Oh gosh, Yeah, that's it's like everyone. When we're looking

0:56:01.120 --> 0:56:04.760
<v Speaker 5>at trends in cancer over the last like thirty years

0:56:04.840 --> 0:56:09.440
<v Speaker 5>or so, there's not one story that emerges. The trends

0:56:09.440 --> 0:56:12.760
<v Speaker 5>that we have seen really vary depending on the type

0:56:12.800 --> 0:56:15.400
<v Speaker 5>of cancer that you're looking at and depending on where

0:56:15.480 --> 0:56:18.600
<v Speaker 5>in the globe that you're looking. So the incidences while

0:56:18.640 --> 0:56:23.040
<v Speaker 5>we know like overall numbers are increasing, the incidences of

0:56:23.120 --> 0:56:27.280
<v Speaker 5>specific types of cancer might be increasing, like prostate breast cancer,

0:56:27.320 --> 0:56:31.040
<v Speaker 5>pancrettic cancer. Some of these might vary by sex, like

0:56:31.080 --> 0:56:35.239
<v Speaker 5>they're increasing in males but maybe decreasing or stagnant in females,

0:56:35.280 --> 0:56:39.839
<v Speaker 5>and viceversa. Cancer exactly exactly. And the same thing goes

0:56:39.880 --> 0:56:41.160
<v Speaker 5>for trends in mortality.

0:56:41.480 --> 0:56:41.760
<v Speaker 1>Though.

0:56:42.040 --> 0:56:45.520
<v Speaker 5>The good news is that cancer mortality has been declining

0:56:45.680 --> 0:56:50.040
<v Speaker 5>across the board, but that's not necessarily true for all

0:56:50.280 --> 0:56:55.640
<v Speaker 5>populations or for all types of cancer. And you had

0:56:55.640 --> 0:56:57.799
<v Speaker 5>talked about, and we've talked about now a lot these

0:56:57.840 --> 0:57:02.160
<v Speaker 5>disparities that we see in cancer are not getting any better, No,

0:57:02.280 --> 0:57:05.920
<v Speaker 5>they really are not. They're getting worse, if anything. For example,

0:57:06.000 --> 0:57:09.080
<v Speaker 5>compared to white folks in the US, all other racial

0:57:09.080 --> 0:57:11.400
<v Speaker 5>and ethnic groups are more likely to be diagnosed with

0:57:11.520 --> 0:57:15.560
<v Speaker 5>later stages of cancer. And that's especially true for breast cancer,

0:57:15.719 --> 0:57:19.320
<v Speaker 5>lung cancer, prostate cancer, cervical cancer, colon cancer. These are

0:57:19.360 --> 0:57:22.640
<v Speaker 5>all the cancers that we can screen for that we

0:57:22.680 --> 0:57:27.400
<v Speaker 5>could potentially catch earlier. We also see higher mortality rates

0:57:27.600 --> 0:57:31.160
<v Speaker 5>compared to white counterparts for all cancers across the board,

0:57:31.840 --> 0:57:34.360
<v Speaker 5>and in the case of Black Americans, we see a

0:57:34.440 --> 0:57:37.160
<v Speaker 5>higher incidence of cancer for a lot of cancers, but

0:57:37.240 --> 0:57:40.479
<v Speaker 5>not all cancers, compared to white Americans. And like you said,

0:57:40.520 --> 0:57:44.480
<v Speaker 5>it's not just racial and ethnic disparities. Those are very striking.

0:57:45.960 --> 0:57:48.600
<v Speaker 5>It is so there are so many levels on which

0:57:48.640 --> 0:57:52.800
<v Speaker 5>we see these disparities, socioeconomics, whether or not your insurance

0:57:52.800 --> 0:58:00.280
<v Speaker 5>covers anything, cancer can and does affect everyone. Yes, But

0:58:00.600 --> 0:58:03.080
<v Speaker 5>what a lot of these inequalities show us is that

0:58:03.160 --> 0:58:06.520
<v Speaker 5>a lot of the risk factors that contribute to the

0:58:06.560 --> 0:58:11.320
<v Speaker 5>development of cancer, including the ability to identify and identify

0:58:11.360 --> 0:58:15.240
<v Speaker 5>early and adequately treat cancers, are not equal, right, And

0:58:15.280 --> 0:58:19.480
<v Speaker 5>the burden of these risks and the lack of access

0:58:19.960 --> 0:58:23.280
<v Speaker 5>is falling on groups that have historically and continue to

0:58:23.280 --> 0:58:27.640
<v Speaker 5>be disenfranchised, especially in this country, but also across the globe, right,

0:58:28.000 --> 0:58:30.800
<v Speaker 5>And this is not something that's reflective of individual choices

0:58:30.800 --> 0:58:33.360
<v Speaker 5>that people are making. This is, like you said, reflective

0:58:33.400 --> 0:58:38.080
<v Speaker 5>of our systems that have failed people. Yeah, so that's

0:58:38.280 --> 0:58:39.400
<v Speaker 5>all very depressing.

0:58:39.520 --> 0:58:42.680
<v Speaker 1>It's just like so many different stages, right, Like there

0:58:42.680 --> 0:58:47.520
<v Speaker 1>exactly prevention, screening, treatment, during treatment, like what sort of

0:58:47.520 --> 0:58:50.320
<v Speaker 1>treatments do you actually get? Exactly are you able to

0:58:50.320 --> 0:58:52.400
<v Speaker 1>take any time off work? Are you able to afford treatment?

0:58:52.960 --> 0:58:56.400
<v Speaker 1>What is your insurance company decide to that they're going

0:58:56.440 --> 0:58:57.080
<v Speaker 1>to cover for you?

0:58:57.240 --> 0:58:58.600
<v Speaker 3>Or feel like you're disgusting?

0:58:58.720 --> 0:59:03.160
<v Speaker 5>Yeah, yeah, so yeah, so there's a lot and if

0:59:03.160 --> 0:59:05.320
<v Speaker 5>we're also looking at like what is the most prevalent

0:59:05.360 --> 0:59:08.240
<v Speaker 5>type of cancer and those kinds of things that actually

0:59:08.280 --> 0:59:12.320
<v Speaker 5>really varies globally, that makes sense and it's very it

0:59:12.680 --> 0:59:15.520
<v Speaker 5>tells you a lot about how much environment really does

0:59:15.560 --> 0:59:17.880
<v Speaker 5>play a role in cancer development, like.

0:59:17.840 --> 0:59:19.560
<v Speaker 1>The age structure of a population till one.

0:59:19.840 --> 0:59:23.120
<v Speaker 5>Percent, but it really can very like region to region

0:59:25.000 --> 0:59:28.000
<v Speaker 5>across the globe. Lung cancer is still kind of one

0:59:28.000 --> 0:59:31.080
<v Speaker 5>of the number one sometimes it's number two, depending on

0:59:31.120 --> 0:59:33.360
<v Speaker 5>the specific area that you're looking at but lung cancer

0:59:33.400 --> 0:59:35.680
<v Speaker 5>is definitely one of the top. Breast cancer and prostate

0:59:35.720 --> 0:59:38.240
<v Speaker 5>cancer are also some of the top cancers in terms

0:59:38.280 --> 0:59:41.160
<v Speaker 5>of how common they are as well as their deaths.

0:59:41.640 --> 0:59:45.720
<v Speaker 5>Even though breast and prostate cancer, for example, have very high,

0:59:45.920 --> 0:59:48.160
<v Speaker 5>like five and ten year survival rates compared to other

0:59:48.200 --> 0:59:51.080
<v Speaker 5>types of cancers, but just because of how prevalent they are,

0:59:51.680 --> 0:59:54.600
<v Speaker 5>we also see them having very high mortality rates. Like globally,

0:59:55.920 --> 0:59:58.320
<v Speaker 5>childhood cancers, which I don't think that we spent enough

0:59:58.320 --> 1:00:01.520
<v Speaker 5>time talking about because there's too much to cover. They

1:00:01.560 --> 1:00:04.600
<v Speaker 5>account for about one and a half percent of all

1:00:04.640 --> 1:00:09.320
<v Speaker 5>cancers globally and one percent of cancer deaths worldwide, but

1:00:09.680 --> 1:00:12.920
<v Speaker 5>they also account for over three percent of the disability

1:00:12.920 --> 1:00:16.280
<v Speaker 5>adjusted life years that we see. So childhood cancers really

1:00:16.360 --> 1:00:18.720
<v Speaker 5>like we should do some specific episodes on some of

1:00:18.760 --> 1:00:21.440
<v Speaker 5>those because there's a lot more detail there that we

1:00:21.480 --> 1:00:28.200
<v Speaker 5>haven't covered. Yes, so improving our treatment we know can

1:00:28.240 --> 1:00:30.240
<v Speaker 5>help with some of these numbers, especially when we look

1:00:30.240 --> 1:00:34.360
<v Speaker 5>at mortality. But like you said, Aaron, we're never going

1:00:34.400 --> 1:00:37.840
<v Speaker 5>to be able to prevent all cancers. So I want

1:00:37.880 --> 1:00:40.000
<v Speaker 5>to talk a little bit more detail about what the

1:00:40.040 --> 1:00:44.920
<v Speaker 5>future of screening and prevention might look like right, Like

1:00:44.960 --> 1:00:47.920
<v Speaker 5>you said, we have pretty widespread screening programs for a

1:00:48.000 --> 1:00:49.400
<v Speaker 5>number of types of cancer.

1:00:49.200 --> 1:00:51.800
<v Speaker 1>Like more that I didn't even know some of these.

1:00:51.920 --> 1:00:53.360
<v Speaker 1>I was like, WHOA, I didn't know we had a

1:00:53.360 --> 1:00:54.680
<v Speaker 1>screening tool for that. That's great.

1:00:54.840 --> 1:01:00.720
<v Speaker 5>Yeah, so breast cancer, cervical cancer, colorectal cancer, lung cancer,

1:01:01.160 --> 1:01:03.400
<v Speaker 5>though only in very specific populations. All of these are

1:01:03.560 --> 1:01:07.920
<v Speaker 5>specific populations, and prostate cancer. Not every country across the

1:01:07.960 --> 1:01:11.360
<v Speaker 5>globe has robust screening programs in place for all of

1:01:11.400 --> 1:01:15.640
<v Speaker 5>these cancers, but many have at least some type of

1:01:15.640 --> 1:01:18.400
<v Speaker 5>screening program available for all of these types of cancers,

1:01:18.440 --> 1:01:20.360
<v Speaker 5>even if the way that they implement them might be

1:01:20.400 --> 1:01:23.840
<v Speaker 5>slightly different. Like other countries might use colonoscopy a lot

1:01:23.920 --> 1:01:25.600
<v Speaker 5>less than we do here in the US, but they

1:01:25.600 --> 1:01:28.840
<v Speaker 5>still screen for colon cancer in various ways. And like

1:01:28.880 --> 1:01:32.800
<v Speaker 5>you said, the goal of cancer screening is to identify

1:01:32.960 --> 1:01:36.720
<v Speaker 5>either pre cancerous conditions like we can with cervical cancer

1:01:36.760 --> 1:01:40.480
<v Speaker 5>and colon cancer, which means that we could potentially treat

1:01:40.520 --> 1:01:45.960
<v Speaker 5>something before it ever becomes cancer, or to identify early

1:01:46.120 --> 1:01:49.000
<v Speaker 5>stage cancers if possible, and that's something that we do

1:01:49.080 --> 1:01:52.920
<v Speaker 5>with like breast cancer and lung cancer screening and prostate

1:01:52.920 --> 1:01:57.440
<v Speaker 5>cancer as well, and now because of advances that we

1:01:57.480 --> 1:02:01.840
<v Speaker 5>have had in technology include things like genetic testing as

1:02:01.880 --> 1:02:05.080
<v Speaker 5>well as a better understanding of you know, these tumor

1:02:05.160 --> 1:02:08.800
<v Speaker 5>suppressor genes, these ANCA genes, all of these different genes

1:02:08.800 --> 1:02:11.200
<v Speaker 5>and genetic markers that are associated with an increased risk

1:02:11.240 --> 1:02:14.640
<v Speaker 5>of cancer. There's also a lot of interest in screening

1:02:14.720 --> 1:02:20.280
<v Speaker 5>for those types of things, which wouldn't be identifying cancers

1:02:20.480 --> 1:02:25.080
<v Speaker 5>or pre cancers. It's identifying individuals who might be at

1:02:25.200 --> 1:02:28.600
<v Speaker 5>higher risk for developing cancer later on in your.

1:02:28.480 --> 1:02:31.640
<v Speaker 1>Life, characterizing your individual lifetime risk exactly.

1:02:32.160 --> 1:02:35.280
<v Speaker 5>And what is so interesting and different about this is

1:02:35.320 --> 1:02:40.400
<v Speaker 5>that for that to be helpful, we have to then

1:02:40.520 --> 1:02:44.040
<v Speaker 5>have a way to detect and treat or prevent the

1:02:44.160 --> 1:02:49.680
<v Speaker 5>cancers that you might be at higher risk for right ideally,

1:02:49.920 --> 1:02:52.720
<v Speaker 5>and that I think is where we still aren't as

1:02:52.800 --> 1:02:55.920
<v Speaker 5>far ahead as I think that we would hope that

1:02:55.960 --> 1:02:56.440
<v Speaker 5>we could be.

1:02:56.560 --> 1:02:58.360
<v Speaker 3>If that is a lot of way of saying.

1:02:58.080 --> 1:03:01.200
<v Speaker 1>That, I mean, I think, yeah, like using like leaf

1:03:01.240 --> 1:03:04.720
<v Speaker 1>Remini syndrome as an example, like they can increase screening

1:03:04.760 --> 1:03:07.840
<v Speaker 1>capacity a lot and have a better chance of catching

1:03:07.880 --> 1:03:11.520
<v Speaker 1>cancers early, but like our treatment is still limited to

1:03:11.560 --> 1:03:15.400
<v Speaker 1>the existing treatments today, and so it's like there's benefit,

1:03:15.560 --> 1:03:19.320
<v Speaker 1>but yeah, we're there's so much more that we could

1:03:19.360 --> 1:03:20.680
<v Speaker 1>do exactly exactly.

1:03:20.720 --> 1:03:23.360
<v Speaker 5>And I think that being able to do this kind

1:03:23.400 --> 1:03:26.560
<v Speaker 5>of genetic testing is going to allow us to develop

1:03:26.640 --> 1:03:31.480
<v Speaker 5>better early screening and early treatment kind of protocols, right

1:03:31.520 --> 1:03:33.320
<v Speaker 5>because we will have this data to be able to

1:03:33.320 --> 1:03:37.120
<v Speaker 5>do this. But it already has reshaped the way that

1:03:37.200 --> 1:03:40.280
<v Speaker 5>medicine decides who to screen and how to screen for

1:03:40.360 --> 1:03:43.840
<v Speaker 5>certain cancers. For example, if you have a Braca mutation,

1:03:44.600 --> 1:03:47.680
<v Speaker 5>then the recommendations for how often you are screened for

1:03:47.800 --> 1:03:50.560
<v Speaker 5>cancers and what types of screening you are going to

1:03:50.560 --> 1:03:53.240
<v Speaker 5>be recommended to get, and what cancers we are going

1:03:53.280 --> 1:03:56.920
<v Speaker 5>to be screening for. That's vastly different than someone without

1:03:56.960 --> 1:03:59.480
<v Speaker 5>a Braca mutation or who we don't know if they

1:03:59.480 --> 1:04:00.440
<v Speaker 5>have a Brack mutation.

1:04:00.640 --> 1:04:02.200
<v Speaker 3>Yeah, so it is.

1:04:03.640 --> 1:04:08.400
<v Speaker 5>It has changed the game really entirely so far, though

1:04:08.520 --> 1:04:10.720
<v Speaker 5>for a lot of cancers we still don't have any

1:04:10.720 --> 1:04:12.760
<v Speaker 5>way to screen for it. We don't have any way

1:04:12.800 --> 1:04:19.320
<v Speaker 5>to reliably screen large populations, especially for these types of cancers.

1:04:19.440 --> 1:04:22.000
<v Speaker 5>Even if someone who has maybe a genetic mutation, we

1:04:22.080 --> 1:04:26.000
<v Speaker 5>might do something specific like doing serial ultrasounds in someone

1:04:26.080 --> 1:04:28.440
<v Speaker 5>to try and detect ovarian cancer. If you have a

1:04:28.480 --> 1:04:31.360
<v Speaker 5>brac A mutation, that's still not going to be recommended

1:04:31.400 --> 1:04:33.560
<v Speaker 5>for the general population because of what you mentioned about

1:04:33.600 --> 1:04:36.480
<v Speaker 5>how we have to implement these screening protocols to make

1:04:36.520 --> 1:04:38.480
<v Speaker 5>sure that we're not having too many false positives, too

1:04:38.480 --> 1:04:40.360
<v Speaker 5>many false negatives, all of this stuff.

1:04:40.400 --> 1:04:42.280
<v Speaker 1>I mean, it comes down to there has to be

1:04:42.320 --> 1:04:44.160
<v Speaker 1>an individual. There has to be a benefit to the

1:04:44.200 --> 1:04:47.720
<v Speaker 1>individual who is receiving the screening, not just this information

1:04:47.880 --> 1:04:49.920
<v Speaker 1>will help society at large.

1:04:49.600 --> 1:04:53.360
<v Speaker 5>Exactly, exactly. So for a lot of cancersly ovarian cancer,

1:04:53.400 --> 1:04:56.440
<v Speaker 5>like stomach cancer, like brain cancers, like bone cancers, thyroid cancers,

1:04:56.480 --> 1:04:59.960
<v Speaker 5>pancreatic cancers, head and net cancers, we don't have screening

1:05:00.080 --> 1:05:03.080
<v Speaker 5>for a lot of these types of cancers. But the

1:05:03.120 --> 1:05:06.360
<v Speaker 5>more research that we do, the more tests that we

1:05:06.400 --> 1:05:10.760
<v Speaker 5>can develop. Yeah, and then we could potentially have screening

1:05:10.920 --> 1:05:14.680
<v Speaker 5>for some of these cancers. So one of the things

1:05:14.720 --> 1:05:16.920
<v Speaker 5>I probably haven't said, I don't think I've said it

1:05:16.920 --> 1:05:18.920
<v Speaker 5>at all in this whole series is the words Ai.

1:05:20.040 --> 1:05:21.040
<v Speaker 1>No, we haven't, so we.

1:05:21.000 --> 1:05:24.280
<v Speaker 5>Haven't, So let me say it now, Ai. This is

1:05:24.280 --> 1:05:27.600
<v Speaker 5>one of the places where AI and machine based learning

1:05:27.680 --> 1:05:32.520
<v Speaker 5>like in general can really be helpful in coming up

1:05:32.600 --> 1:05:37.360
<v Speaker 5>with and developing protocols for not just the diagnosis and screening,

1:05:37.600 --> 1:05:39.960
<v Speaker 5>but also the treatment of cancers. And so that's like

1:05:40.000 --> 1:05:42.280
<v Speaker 5>a huge area of research is how can we leverage

1:05:42.280 --> 1:05:46.200
<v Speaker 5>AI in better detection, in coming up with screening protocols,

1:05:46.520 --> 1:05:48.800
<v Speaker 5>in sorting through all of this data that we have,

1:05:49.000 --> 1:05:51.439
<v Speaker 5>in coming up with treatment plans and things like that.

1:05:52.120 --> 1:05:54.920
<v Speaker 5>But there also is a lot of research interest in

1:05:55.280 --> 1:06:00.800
<v Speaker 5>developing new biomarkers to use as screening tools for cancers,

1:06:00.840 --> 1:06:03.160
<v Speaker 5>both for cancers that we already have screening tools for,

1:06:03.880 --> 1:06:06.680
<v Speaker 5>and I'll give one really great example, which is colon cancer.

1:06:07.560 --> 1:06:10.959
<v Speaker 5>So colon cancer there typically we screen for it either

1:06:11.040 --> 1:06:14.400
<v Speaker 5>with a colonoscopy, which is an invasive procedure that you

1:06:14.480 --> 1:06:17.120
<v Speaker 5>have to prep for that a lot of people have

1:06:17.440 --> 1:06:20.880
<v Speaker 5>quite a lot of difficulty with the prep and that

1:06:21.840 --> 1:06:23.680
<v Speaker 5>has its own set of risks that come with it.

1:06:23.720 --> 1:06:27.000
<v Speaker 5>Because it is invasive. You can have you know, injuries

1:06:27.000 --> 1:06:30.480
<v Speaker 5>that happen, bleeding that happens during that procedure. It also

1:06:30.920 --> 1:06:34.280
<v Speaker 5>is a wonderful thing because it can identify pre cancers

1:06:34.280 --> 1:06:36.560
<v Speaker 5>and remove them. So it's not just screening. It's also

1:06:36.640 --> 1:06:41.440
<v Speaker 5>diagnostic and it's therapeutic, but it's also time consuming and

1:06:41.520 --> 1:06:43.360
<v Speaker 5>you have to have the resources. So we have a

1:06:43.360 --> 1:06:45.920
<v Speaker 5>lot of other screening tools for colon cancer, including stool

1:06:45.960 --> 1:06:49.520
<v Speaker 5>based testing where we can look for markers of tumors

1:06:50.000 --> 1:06:53.000
<v Speaker 5>and blood, which is commonly found in people who have

1:06:53.040 --> 1:06:57.080
<v Speaker 5>colon cancer, even or pre cancers. But there's also a

1:06:57.120 --> 1:06:59.800
<v Speaker 5>new blood test because doing a stool test might be

1:06:59.880 --> 1:07:02.960
<v Speaker 5>very very unpleasant for some people or might feel like

1:07:03.120 --> 1:07:05.120
<v Speaker 5>not something that they want to participate in, or might

1:07:05.160 --> 1:07:07.320
<v Speaker 5>be difficult to do. Sure, but a blood test a

1:07:07.320 --> 1:07:08.600
<v Speaker 5>lot of times you're going to get that done at

1:07:08.640 --> 1:07:11.480
<v Speaker 5>your doctor no matter what. So there is actually a

1:07:11.520 --> 1:07:14.360
<v Speaker 5>new FDA approved colon cancer blood test that just was approved,

1:07:14.400 --> 1:07:16.960
<v Speaker 5>like very recently in the last year or so. I

1:07:16.960 --> 1:07:19.320
<v Speaker 5>don't know that anyone's covering yet because it's still expensive,

1:07:19.400 --> 1:07:22.880
<v Speaker 5>but okay, that's a US issue, yes, and it's only

1:07:22.920 --> 1:07:24.800
<v Speaker 5>a matter of time before we have more and more

1:07:24.880 --> 1:07:27.280
<v Speaker 5>of these tests. There's also a lot of interest in

1:07:27.280 --> 1:07:32.600
<v Speaker 5>what are called multi cancer Early Detection Tests or MCEED. Okay,

1:07:32.840 --> 1:07:35.760
<v Speaker 5>to have another acronym for everything, but these are blood

1:07:35.800 --> 1:07:39.440
<v Speaker 5>tests that look for markers of a bunch of different

1:07:39.480 --> 1:07:41.600
<v Speaker 5>cancers rather than just one cancer at a time.

1:07:42.240 --> 1:07:45.000
<v Speaker 1>I really want to know how what.

1:07:45.360 --> 1:07:47.080
<v Speaker 5>Yeah, there's a lot, there's we could do a whole

1:07:47.080 --> 1:07:50.200
<v Speaker 5>episode on these. There's two that I know of that

1:07:50.400 --> 1:07:54.640
<v Speaker 5>are sort of they're not FDA approved for use in

1:07:54.680 --> 1:07:56.560
<v Speaker 5>the US, which means that no one you have to

1:07:56.560 --> 1:07:58.400
<v Speaker 5>pay for them out of pocket, no insurance is going

1:07:58.440 --> 1:08:01.560
<v Speaker 5>to pay for them. They are both also still undergoing

1:08:01.600 --> 1:08:04.600
<v Speaker 5>clinical trials. So one of them is a trials that

1:08:04.640 --> 1:08:07.680
<v Speaker 5>are out in the UK, and it's called Gallery I

1:08:07.680 --> 1:08:10.520
<v Speaker 5>think that's how you say it. And it looks for

1:08:10.560 --> 1:08:13.360
<v Speaker 5>biomarkers of more than fifty different types of cancers, many

1:08:13.400 --> 1:08:15.720
<v Speaker 5>of which we don't have any other screening tests for.

1:08:16.360 --> 1:08:20.120
<v Speaker 3>How reliable is it? Yeah, so that's a it's a thing. Okay,

1:08:20.160 --> 1:08:21.080
<v Speaker 3>it's a great question.

1:08:21.280 --> 1:08:26.599
<v Speaker 5>So the specificity of these tends to be relatively high,

1:08:27.000 --> 1:08:34.200
<v Speaker 5>like ninety percent ish, meaning that if it is positive,

1:08:34.520 --> 1:08:38.800
<v Speaker 5>then it's likeli er that there is something there is

1:08:38.800 --> 1:08:40.679
<v Speaker 5>that what that's beificed is that sensitive?

1:08:40.760 --> 1:08:41.720
<v Speaker 1>What sensitivity then?

1:08:41.880 --> 1:08:45.160
<v Speaker 5>So a sensitivity is quite low, which means that a

1:08:45.240 --> 1:08:49.080
<v Speaker 5>negative test doesn't necessarily rule anything out.

1:08:49.320 --> 1:08:52.479
<v Speaker 1>So still high rates of false negatives, false.

1:08:52.360 --> 1:08:57.360
<v Speaker 5>Negatives, Yeah, Okay, So it's they're not perfect by any means.

1:08:57.760 --> 1:08:59.680
<v Speaker 5>And the other issue with some of them is that

1:08:59.720 --> 1:09:03.920
<v Speaker 5>they might not help Sometimes you might end up with

1:09:03.960 --> 1:09:07.599
<v Speaker 5>this possible cancer but of unknown origin, like where are

1:09:07.600 --> 1:09:10.040
<v Speaker 5>these cells? Because it's a blood test, and so you're

1:09:10.040 --> 1:09:14.719
<v Speaker 5>looking for DNA fragments or you're looking for like methylation products,

1:09:14.720 --> 1:09:17.759
<v Speaker 5>you're looking for these like kind of tumor marker type things,

1:09:19.040 --> 1:09:22.720
<v Speaker 5>and we might not necessarily be able to identify all

1:09:22.760 --> 1:09:24.760
<v Speaker 5>the time where that might be coming from in terms

1:09:24.760 --> 1:09:26.680
<v Speaker 5>of the tissue of origin and things like that.

1:09:26.920 --> 1:09:29.280
<v Speaker 1>And so would a test like a blood test like

1:09:29.320 --> 1:09:32.519
<v Speaker 1>this be more useful based on of course, more useful

1:09:32.560 --> 1:09:34.920
<v Speaker 1>based on how much we know about a particular cancer

1:09:34.960 --> 1:09:38.400
<v Speaker 1>and the tumor antigens and stuff like that. But also

1:09:38.840 --> 1:09:41.479
<v Speaker 1>I am assuming site of origin plays a big role

1:09:41.479 --> 1:09:43.640
<v Speaker 1>in the likelihood that any of these products will end

1:09:43.720 --> 1:09:47.200
<v Speaker 1>up in whatever quantities in the bloodstream large enough to

1:09:47.200 --> 1:09:48.320
<v Speaker 1>be detected on that testing.

1:09:48.600 --> 1:09:51.000
<v Speaker 5>Yeah, and they're different. So there's another one aside from

1:09:51.000 --> 1:09:53.639
<v Speaker 5>the gallery that's called cancer Guard that was developed from

1:09:53.680 --> 1:09:57.320
<v Speaker 5>a clinical trial at Johns Hopkins called Cancer Seek. This

1:09:57.360 --> 1:09:59.360
<v Speaker 5>one also like you can buy it and you could

1:09:59.360 --> 1:10:01.160
<v Speaker 5>get it done to have your doctor order it. You're

1:10:01.160 --> 1:10:05.120
<v Speaker 5>gonna have to pay for it. But they're they're very

1:10:05.160 --> 1:10:08.240
<v Speaker 5>interesting and I think that they It's what's interesting too

1:10:08.320 --> 1:10:12.080
<v Speaker 5>to me about these is that they exist still in

1:10:12.120 --> 1:10:16.200
<v Speaker 5>the research realm and yet you as an individual could

1:10:16.200 --> 1:10:20.080
<v Speaker 5>go and buy this thing, and as clinicians and as

1:10:20.120 --> 1:10:22.479
<v Speaker 5>medical professionals, I don't think we quite know how to

1:10:22.600 --> 1:10:25.439
<v Speaker 5>bridge the gap yet because we don't have that data

1:10:25.479 --> 1:10:27.600
<v Speaker 5>necessarily to back us up on, like what do we

1:10:27.760 --> 1:10:31.600
<v Speaker 5>do with these tests once we get these results? And

1:10:31.720 --> 1:10:36.000
<v Speaker 5>of course how are these going to be implemented? Who

1:10:36.040 --> 1:10:37.800
<v Speaker 5>is going to get access to them? Because right now

1:10:37.800 --> 1:10:40.880
<v Speaker 5>they're between seven hundred and one thousand dollars or so.

1:10:41.200 --> 1:10:45.080
<v Speaker 1>They're not FDA approved, but you can get one yep.

1:10:45.240 --> 1:10:47.479
<v Speaker 1>I mean I know a lot of things it's that

1:10:47.520 --> 1:10:48.280
<v Speaker 1>you could still get.

1:10:48.280 --> 1:10:50.320
<v Speaker 3>But like, yeah, they're.

1:10:50.160 --> 1:10:53.680
<v Speaker 5>Approved under like a research license type of thing, so

1:10:53.800 --> 1:10:56.160
<v Speaker 5>not through the FDA, but there's some kind of like

1:10:56.280 --> 1:11:00.760
<v Speaker 5>research license that they have a clinical approval for. And

1:11:00.800 --> 1:11:02.600
<v Speaker 5>so it's not like they're just I'm not saying that

1:11:02.600 --> 1:11:04.120
<v Speaker 5>these are wild and wild wild West.

1:11:04.320 --> 1:11:05.519
<v Speaker 3>They're very interesting.

1:11:05.640 --> 1:11:09.000
<v Speaker 1>I think I'm just like, uh, suspicious because of Elizabeth

1:11:09.000 --> 1:11:12.360
<v Speaker 1>Holmes and therapeus. Oh, you know, a hundred percent yeah

1:11:12.680 --> 1:11:15.559
<v Speaker 1>panel at least it's like for everything, Yeah, a whole

1:11:15.600 --> 1:11:16.200
<v Speaker 1>health panel.

1:11:16.479 --> 1:11:18.280
<v Speaker 3>I mean, I know it is, but but it is

1:11:18.320 --> 1:11:19.559
<v Speaker 3>really interesting, right.

1:11:19.680 --> 1:11:21.880
<v Speaker 1>It's I mean and like and that also is the

1:11:22.000 --> 1:11:23.280
<v Speaker 1>dream or it is the dream?

1:11:23.360 --> 1:11:26.519
<v Speaker 5>It is one hundred percent, it is the dream? And

1:11:26.760 --> 1:11:29.120
<v Speaker 5>how are these going to be implemented? Who's going right now?

1:11:29.320 --> 1:11:31.080
<v Speaker 5>You would only have access to this if you have

1:11:31.160 --> 1:11:34.400
<v Speaker 5>the means, because we also don't know how often do

1:11:34.479 --> 1:11:37.360
<v Speaker 5>we need to be using these tests to accurately screen

1:11:37.479 --> 1:11:41.519
<v Speaker 5>for cancers? Right, For mammograms, we have an interval on

1:11:41.600 --> 1:11:45.280
<v Speaker 5>which we recommend, an age at which we recommend people start,

1:11:45.800 --> 1:11:48.639
<v Speaker 5>and an interval at which we recommend that people get screened.

1:11:48.640 --> 1:11:51.000
<v Speaker 5>Same thing for colon cancer, same thing for server cook cancer.

1:11:51.160 --> 1:11:54.000
<v Speaker 5>And those guidelines might change based on where you live

1:11:54.040 --> 1:11:56.639
<v Speaker 5>and how data has been interpreted in the UK versus

1:11:56.640 --> 1:11:59.600
<v Speaker 5>the US or by you know, the American College of

1:11:59.680 --> 1:12:03.680
<v Speaker 5>Radio all versus the USPSTF. Sure, but we still have

1:12:03.760 --> 1:12:07.559
<v Speaker 5>these consensus guidelines. We don't yet have these for this,

1:12:07.680 --> 1:12:09.880
<v Speaker 5>so you know, the companies are saying it's an annual test,

1:12:10.280 --> 1:12:11.920
<v Speaker 5>doesn't need to be an annual test? Could it be

1:12:11.960 --> 1:12:13.679
<v Speaker 5>in every three years, Like, well, there's just so many

1:12:13.760 --> 1:12:16.280
<v Speaker 5>unknowns about these but I do think that this is

1:12:16.280 --> 1:12:19.439
<v Speaker 5>the future of cancer screenings is going to be blood tests,

1:12:19.520 --> 1:12:20.320
<v Speaker 5>and it's going to.

1:12:20.240 --> 1:12:22.519
<v Speaker 1>Be invasive, fewer side effects.

1:12:22.040 --> 1:12:24.800
<v Speaker 5>And that detect a wider range of cancers that we're

1:12:24.840 --> 1:12:25.600
<v Speaker 5>able to screen for.

1:12:25.840 --> 1:12:26.520
<v Speaker 1>Yeah.

1:12:26.600 --> 1:12:32.360
<v Speaker 5>Right, it's there's a lot that has the potential in

1:12:32.400 --> 1:12:36.960
<v Speaker 5>the future, especially because there are so many cancers, and

1:12:37.000 --> 1:12:39.080
<v Speaker 5>I think that this has such a huge potential for

1:12:39.200 --> 1:12:42.439
<v Speaker 5>rare cancers, for us to be able to identify them better,

1:12:42.960 --> 1:12:45.840
<v Speaker 5>for us to be able to, you know, potentially do

1:12:45.960 --> 1:12:48.760
<v Speaker 5>a lot more research on these rare cancers by identifying

1:12:48.760 --> 1:12:51.560
<v Speaker 5>them early, by having a wider range of treatments available

1:12:51.600 --> 1:12:53.840
<v Speaker 5>in clinical trials and things like that. Who knows, that's

1:12:53.840 --> 1:12:56.760
<v Speaker 5>my I think that's my hope and dream is that

1:12:56.800 --> 1:12:58.760
<v Speaker 5>these kinds of tools make it possible.

1:12:58.960 --> 1:13:02.360
<v Speaker 1>Yeah, which we had a crystal I know, Yeah, but.

1:13:02.360 --> 1:13:05.679
<v Speaker 5>I think it's probably the future. That's my guess. Okay, okay,

1:13:05.840 --> 1:13:07.320
<v Speaker 5>multi cancer early detection to.

1:13:07.360 --> 1:13:10.040
<v Speaker 1>Us, We'll check in ten years where we are five.

1:13:09.960 --> 1:13:13.439
<v Speaker 5>Years probably honestly sure, And there's like there's so much

1:13:13.479 --> 1:13:17.479
<v Speaker 5>more I think to the story of cancer there's so

1:13:17.479 --> 1:13:21.360
<v Speaker 5>many types of cancers that deserve their whole own episodes.

1:13:21.600 --> 1:13:24.400
<v Speaker 1>I mean every cancer does, not just so many, but.

1:13:24.400 --> 1:13:26.800
<v Speaker 3>Every single Yeah. Well, but there are so many types

1:13:26.840 --> 1:13:27.559
<v Speaker 3>of cancers, and.

1:13:27.479 --> 1:13:28.960
<v Speaker 1>There were so many types of cancers. There are so

1:13:28.960 --> 1:13:32.240
<v Speaker 1>many different types of approaches, stories of individual cancer discovery,

1:13:32.360 --> 1:13:34.680
<v Speaker 1>stories of cancer treatment development.

1:13:34.840 --> 1:13:38.400
<v Speaker 5>Like, there's so much going on with increasing incidents of cancers,

1:13:38.479 --> 1:13:41.320
<v Speaker 5>especially in young people, for things like breast cancer, for

1:13:41.360 --> 1:13:44.880
<v Speaker 5>things like colon cancer and things like this, like that

1:13:45.080 --> 1:13:49.200
<v Speaker 5>is things that we need to cover in the future. Yeah,

1:13:49.240 --> 1:13:50.960
<v Speaker 5>and for now, this is where I shall end.

1:13:51.240 --> 1:13:58.040
<v Speaker 1>Yeah, God, I know it is. I don't even know

1:13:58.080 --> 1:13:59.800
<v Speaker 1>what to say. I think we have said so many

1:13:59.800 --> 1:14:01.799
<v Speaker 1>words words over the past few.

1:14:01.640 --> 1:14:04.320
<v Speaker 3>Weeks, worded it out, worded it out.

1:14:04.520 --> 1:14:09.000
<v Speaker 1>I think that like the again kind of like I'll

1:14:09.040 --> 1:14:13.799
<v Speaker 1>echo what we talked about last episode, which was how

1:14:13.840 --> 1:14:19.080
<v Speaker 1>many people have devoted their lives to understanding cancer, to

1:14:19.280 --> 1:14:24.400
<v Speaker 1>better treating it, to preventing it, to participating in clinical

1:14:24.479 --> 1:14:28.080
<v Speaker 1>trials in other ways, like to raising awareness and funding

1:14:28.160 --> 1:14:31.400
<v Speaker 1>like it is. It blows my mind. And when we

1:14:31.479 --> 1:14:34.080
<v Speaker 1>think about like and I think about the people in

1:14:34.120 --> 1:14:37.479
<v Speaker 1>my life who have died of cancer, been affected by cancer,

1:14:37.520 --> 1:14:41.360
<v Speaker 1>been diagnosed with cancer, undergoing cancer treatment currently. It is

1:14:41.800 --> 1:14:45.400
<v Speaker 1>it's hard to like, I don't know like it. I

1:14:45.840 --> 1:14:48.360
<v Speaker 1>was thinking about you all and all of our pertain

1:14:48.360 --> 1:14:51.200
<v Speaker 1>account providers every with every word that I wrote.

1:14:51.040 --> 1:14:54.439
<v Speaker 3>Trying to be like what is it that I want

1:14:54.479 --> 1:14:55.800
<v Speaker 3>to know? What is it that?

1:14:56.000 --> 1:14:58.880
<v Speaker 1>What is the information that is important to know? And

1:14:58.920 --> 1:15:02.680
<v Speaker 1>so thank you for the opportunity. I guess you all

1:15:02.840 --> 1:15:08.040
<v Speaker 1>for for letting us do this podcast, and we really

1:15:08.040 --> 1:15:10.080
<v Speaker 1>do want to know what you think, and we really

1:15:10.160 --> 1:15:11.920
<v Speaker 1>do want to know what you What else do you

1:15:12.000 --> 1:15:14.240
<v Speaker 1>want to learn about? Yeah, that's always what That is

1:15:14.240 --> 1:15:14.880
<v Speaker 1>what drives us.

1:15:14.880 --> 1:15:16.280
<v Speaker 3>That is what drives us.

1:15:16.360 --> 1:15:19.040
<v Speaker 5>Yeah, it's just like learning new things and being able

1:15:19.080 --> 1:15:21.840
<v Speaker 5>to share them things that is like what gets me

1:15:21.880 --> 1:15:22.759
<v Speaker 5>out of bed in the morning.

1:15:22.960 --> 1:15:24.120
<v Speaker 3>Yeah, So thank you.

1:15:24.600 --> 1:15:30.519
<v Speaker 1>Speaking of learning new things, learning new things, sources, I

1:15:30.600 --> 1:15:33.479
<v Speaker 1>have several I have a lot for this, a lot

1:15:33.560 --> 1:15:37.559
<v Speaker 1>for this. So if you want to there's a the

1:15:38.240 --> 1:15:40.920
<v Speaker 1>where is it the American Cancer Society's Report on the

1:15:40.960 --> 1:15:43.400
<v Speaker 1>Status of Cancer Disparities in the United States? They left

1:15:43.439 --> 1:15:45.719
<v Speaker 1>that one one of those for every year is great

1:15:45.880 --> 1:15:47.800
<v Speaker 1>maps and they are great information to kind of like

1:15:47.880 --> 1:15:51.160
<v Speaker 1>piece apart what's going on and that's also in the

1:15:51.240 --> 1:15:54.320
<v Speaker 1>US specifically, if you want to know more about chimney

1:15:54.320 --> 1:15:58.320
<v Speaker 1>sweeps cancer perceval pot and chimney sweepers cancer of the

1:15:58.360 --> 1:16:02.680
<v Speaker 1>scrotum by Brown and Thorn from nineteen fifty seven and

1:16:02.720 --> 1:16:07.240
<v Speaker 1>then by Croswell at All from twenty ten. Principles of

1:16:06.720 --> 1:16:10.719
<v Speaker 1>Cancer Screening Lessons from History and Study Design issues, great

1:16:10.760 --> 1:16:13.439
<v Speaker 1>overview of like how we do this and why we

1:16:13.520 --> 1:16:16.519
<v Speaker 1>do this, the decisions that go into it. And then

1:16:16.920 --> 1:16:21.400
<v Speaker 1>the classic smoking can cigarette smoking and Lung Cancer paper

1:16:21.479 --> 1:16:24.280
<v Speaker 1>by Doll and Hill from nineteen fifty six Lung Cancer

1:16:24.320 --> 1:16:26.599
<v Speaker 1>and Other Causes of Death in relation to smoking.

1:16:26.720 --> 1:16:31.120
<v Speaker 3>Wow, Yeah, nineteen fifty six, seventeen sixty one. Okay.

1:16:31.960 --> 1:16:34.439
<v Speaker 5>I also have a couple different of the annual reports

1:16:34.439 --> 1:16:37.240
<v Speaker 5>from the American Cancer Society. They're really great, so we'll

1:16:37.240 --> 1:16:41.839
<v Speaker 5>have those. There also was paper from the Lancet, the Global,

1:16:41.840 --> 1:16:44.519
<v Speaker 5>Regional and National Burden of Cancer nineteen ninety to twenty

1:16:44.560 --> 1:16:47.600
<v Speaker 5>twenty three with forecast to twenty fifty yep. So that

1:16:47.640 --> 1:16:50.120
<v Speaker 5>one was from the Global Burden of Disease study. There

1:16:50.200 --> 1:16:53.000
<v Speaker 5>also was one also in the Lancet from twenty twenty

1:16:53.000 --> 1:16:55.200
<v Speaker 5>two that was the Global Burden of cancer attributable to

1:16:55.320 --> 1:16:58.160
<v Speaker 5>risk factors, and so this also looked a lot at

1:16:58.160 --> 1:17:01.720
<v Speaker 5>those disparities and things like that. The I feel like

1:17:01.840 --> 1:17:03.920
<v Speaker 5>I didn't do enough talking about like how much of

1:17:04.400 --> 1:17:07.920
<v Speaker 5>cancer could potentially be preventable, and like lifestyle factors that

1:17:07.960 --> 1:17:10.759
<v Speaker 5>contribute to cancer mortality it's like forty to sixty percent.

1:17:12.040 --> 1:17:13.479
<v Speaker 5>And then I have a whole bunch like links to

1:17:13.520 --> 1:17:16.880
<v Speaker 5>other the Global Cancer Observatory and the Seer statistics and

1:17:16.920 --> 1:17:19.080
<v Speaker 5>things like that, and a bunch of other things about

1:17:19.080 --> 1:17:21.479
<v Speaker 5>cancer screening. There was a great guide actually from twenty

1:17:21.520 --> 1:17:24.720
<v Speaker 5>twenty six in Nature Reviews Clinical Oncology that's called The

1:17:24.720 --> 1:17:27.040
<v Speaker 5>Guide to Cancer Screening that was super awesome overview.
