00:00:00.000 Hey everyone, welcome to a sneak peek episode of the drive podcast. I'm your host, Peter
00:00:15.260 Atiyah. At the end of this short episode, I'll explain how you can access the episodes
00:00:19.240 in full along with a ton of other membership benefits we've created, or you can learn more
00:00:24.040 now by going to peteratiamd.com forward slash subscribe. So without further delay,
00:00:30.160 here's today's sneak peek of the episode. Welcome to a new episode of The Drive. In
00:00:38.940 today's episode, I'm diving into colorectal cancer screening, why colorectal cancer is one of the
00:00:44.380 most preventable cancers we know of, and why getting screening right matters so much. In this
00:00:50.080 episode, I'm going to discuss many things, but among them, how colorectal cancer develops,
00:00:54.340 why colonoscopy is uniquely valuable as both a screening and preventive tool, the troubling rise
00:01:00.980 in early onset colorectal cancer, and how to think clearly about the growing menu of non-invasive
00:01:07.600 screening options and their limitations. If you're not a subscriber, you'll only be able to
00:01:13.040 listen to a sneak peek here. So without further delay, I hope you'll enjoy today's episode of
00:01:18.140 The Drive.
00:01:20.080 Colorectal cancer, or CRC as we'll abbreviate it, is the second leading cause of cancer death
00:01:30.640 in the United States. And it's projected to be responsible for roughly 55,000 deaths this year,
00:01:38.460 according to the American Cancer Society. That puts it behind only lung cancer as far as cancer
00:01:44.600 mortality. And yet, unlike many other cancers, CRC is arguably the most preventable cancer we
00:01:53.700 know of. And the reason for this is that CRC follows a well-characterized slow progression
00:02:00.060 from completely normal tissue to a benign polyp to a precancerous polyp to frank malignancy.
00:02:07.840 and that progression almost always takes years, often a decade or more. And because the colon is
00:02:16.220 a hollow organ and sits outside the body, as crazy as that sounds, we can directly access
00:02:23.760 and visualize it. We have the ability to not only detect those precancerous lesions,
00:02:28.400 but also remove them before they ever become cancer. So no other common cancer screening test
00:02:35.880 can make that claim. A mammogram can detect breast cancer, a low-dose CT scan can detect
00:02:42.180 lung cancer, but neither of those are able to look directly at the cancer. And so a colonoscopy can
00:02:49.340 not only do that, but it can also remove the precancerous lesion in the first place. And yet
00:02:56.600 a 2020 CDC estimate claims that 68% of colorectal cancer deaths may be prevented with screening,
00:03:03.860 even at the traditional recommended intervals. Again, that statistic should stop you cold.
00:03:10.220 We're talking about a cancer that in most cases gives us a decades-long window to intervene,
00:03:15.840 and we're still losing nearly 70% of people out of that 55,000 deaths a year because they never
00:03:24.840 walked through the front door to get a colonoscopy. Even more, I would argue that this number could be
00:03:31.700 closer to 100%, i.e. 100% reduction in colorectal cancer death with more aggressive screening
00:03:40.060 protocols, including starting earlier and screening more often. So today I want to cover
00:03:45.360 this topic comprehensively. We'll start with the basic biology of colorectal cancer and why it's
00:03:50.420 uniquely suited to screening. Then we'll talk about the rise of early onset colorectal cancer
00:03:55.320 in younger adults. From there, we'll go into the colonoscopy itself, how to prepare for one,
00:04:00.040 how to ensure you're getting a high-quality exam, and how to think about screening intervals.
00:04:04.860 We'll discuss real risks and trade-offs, and finally, we'll walk through the growing landscape
00:04:09.160 of non-invasive screening alternatives, both stool-based tests and blood-based tests,
00:04:14.180 and talk about what they can and can't do. The goal here is to leave you with a very clear,
00:04:19.240 practical picture of colorectal cancer screening, whether you're 35 and wondering when to start,
00:04:23.980 or 55 and wondering when your KolaGuard test is good enough.
00:04:29.200 Thank you for listening to today's sneak peek episode of The Drive.
