AMA #56: Cancer screening: pros and cons, screening options, interpreting results, and more

**Peter Attia** (0:11)
Hey, everyone, welcome to a sneak peek, Ask Me Anything, or AMA episode of the Drive podcast. I'm your host, Peter Attia. At the end of this short episode, I'll explain how you can access the AMA episodes in full, along with a ton of other membership benefits we've created. Or you can learn more now by going to peterattiamd.com forward slash subscribe. So without further delay, here's today's sneak peek of the Ask Me Anything episode.
Welcome to Ask Me Anything episode 56 I'm once again joined by my cohost, Nick Stenson. In today's episode, we focus the entire episode on cancer screening. Cancer is what I refer to as one of the four horsemen of death, and it's certainly a killer that we've all been affected by in some way or another. It's a topic that has a lot of confusion around it. That is the screening part of it. And it's one that we see a lot of questions come up.
In today's AMA, we gathered those questions, and we cut for the following. The arguments for and against cancer screening and why some trials may show no benefit to cancer screening. The various modalities that are available to people to screen for different cancers and the pros and cons of each of these. And then we discuss what people should know and how they should think about undergoing cancer screening individually. In other words, all of these data focus on the population, but the question is, how do you take those population data and bring them to your own life as you make decisions? We talk about how you should interpret results and we talk about how people should think about this if they plan to go outside of the relatively narrow and confined screening guidelines and pay out of pocket for various types of screening tests.
I think this is an especially important topic because unlike the other horsemen, cardiovascular disease, neurodegenerative disease, and metabolic disease, cancer is the one for which we have the least insight into how to prevent the disease. We know the obvious environmental triggers such as smoking and poor metabolic health, but the reality of it is, many cases of cancer arise for purely bad luck. In other words, there are many people who are doing everything right and they still get cancer. And as such, early identification of cancer is an essential part of cancer strategy. The reason for that is simple. The lower the burden of tumor, the greater the outcomes in cancer therapy.

Peter, welcome to another AMA, how are you doing?

**Peter Attia** (3:08)
Very well, how are you?

**Nick Stenson** (3:09)
I'm doing good.
Any stories you'd like to share before this AMA starts? I asked this question with nothing in particular in mind, I'm just curious if anything jumps out to you.

**Peter Attia** (3:19)
Yeah, okay, that's funny you say that because I was worried that there was something that I didn't know that I was supposed to be aware of, but no, there are no stories to share.

**Nick Stenson** (3:26)
Okay, all right. With that, we'll get rolling.
So today's AMA is gonna focus all around one topic, and it's a topic we see questions come through weekly. And it seems like there's a lot of confusion around this topic, and that topic is cancer screening.
And ultimately, we see questions around, how should I think about cancer screening? Is it important? Is it beneficial?
There'll be sometimes articles in the news talking about how cancer screening is beneficial, others talking about how studies came out and cancer screening is not beneficial. And so I think it just creates a lot of confusion for people around this topic. And so what we decided to do is just gather all these questions for today's AMA and just kind of go through cancer screening in general. This will be the cases for and against cancer screening, why some trials may show benefit while others don't, what modalities do people have and what are the different options for cancer screening, including the pros and cons of each of them. And then also what should people think about when they get cancer screen, whether it's within traditional guidelines or what we're seeing more so now is if people are paying out of pocket outside of traditional guidelines. And so I think it will be really good. I think at times it can get a teeny bit technical, but I also think that's the price you have to pay to really understand how to think about this. So, all that said, anything you want to add before we get started with the first question?
