70: Cancer in Your 30s?! – The Alarming Rise of Early-Onset Cancer (and How to Prevent It) with Dr. Aaron Hartman
19 Sept 2025 · 6 min
Dr. Aaron Hartman explains why early-onset cancers are rising in people under 50. Diet, alcohol, smoking, and processed foods drive the risk. He covers prevention strategies you can start now.
The new generation is literally coming out of the womb and being exposed to this in formula or in snacks and things like that. So it just makes sense that those that are exposed to processed foods, you expect to see earlier cancers and more aggressive and processed foods alone. Diet and lifestyle alone is associated with about 70% of cancers. You can prevent about 70% of cancers with diet and lifestyle alone. So all of a sudden, you know, not smoking, not drinking and not eating processed foods could be a massive game changer for risk of cancer. Welcome back once again to our short episode on a Friday. This is going to be going out on YouTube as well. And the topic today is what party combo could potentially be increasing your risk for cancer? This actually comes from some recent articles we'll have published. So this may or may not be familiar to you, but as many of you may know, the incidence of cancer is increasing in our country. And there are some things people are doing on a routine basis that greatly increase the risk of cancer and some other things on top of the party combo, which we'll talk about in a second, that by, in and of itself is associated with a significant increased risk for cancer. And I'll be giving you exact statistics. And the question to follow up is, so what? So how does this change your life? And we'll talk about that towards the end. So first thing I want to talk about is actually is an interesting German study looking at people who both smoked and drank alcohol. And no, strange, shouldn't surprise people that people who drank one drink, just one drink of alcohol a day had about a 39% increased risk for early onset colon cancer. So that's not new news. We, you know, for a while we were saying drinking, you know, red wine was healthy for women. A glass a day would lower your risk for heart disease. And we all know that's not the case. That was probably more marketing than anything else. Even one glass of red, even healthy red wine, quote, unquote, can actually increase a female's risk for breast cancer. So the basic gist is that there's really not a healthy quote, unquote, amount of alcohol consumption, not say it's not enjoyable. Not to say that in cultures that drink it, like in Italy, blue zones. Yeah, not saying those things. But here in America, Germany, with western, with our typical lifestyles, any amount of alcohol is not great. But just a daily could increase your risk for early onset colon cancer 39%. That's a concern because colon cancer is on the rise. We've seen an expected rise about 90% in the 20 to 34 age group that's between 2010 and 2025. And it's, it's going up. These numbers are expected to continue to go up. So again, smoking and Alcoh is a bad combination. If you do do them, it's not ideal. And another statistic that was interesting from the study is that teen rates for cancer are surging over 500% since 2000. So from 2000 to today, so that's 25 years in teenage cancer rare but a 500% Galini I keep on 500%. A five time that's easier to say a five time increased risk a teen cancer. The rare is bad. It's really bad. Alcohol is one of the mechanisms that alcohol turns into acetaldehyde which actually damages DNA. One of the anecdotes for antidotes for alcohol is actually NAC and acetylcysteine because it actually improves your liver's capacity for detoxifying. That's also how if you already have a toxic load, you already have a poor diet that makes these things that increase your risk for cancer because of their effect on your liver's ability to detoxify acetyl alhad that makes your risk you go up even more.

But the interesting thing is what else is being associated with an increased risk for in cancer? And the answer is processed foods, especially ultra processed foods. There's other research coming out showing that by itself and you know, put this in perspective. I was actually in medical school before genetically modified foods came out as well some of the newer food additives. And so I didn't have this from birth. The new generation is literally coming out of the womb and being exposed to this in formula or in snacks and things like that. So it just makes sense that those that are exposed to processed foods did you expect to see earlier cancers and more aggressive and on processed foods alone, diet and lifestyle alone is associated with about 70% of cancers. You can prevent about 70% of cancers with Diet and lifestyle alone. So all of a sudden, you know, not smoking, not drinking and not eating processed foods could be a massive game changer for risk of cancer. So, you know, why are these party things? Because, you know, what do you do when you go out to parties? You eat your processed foods, your chips, your soda, your pop, which has a lot of other stuff in it. You might have some alcohol, you might smoke. You know, these are just typical things that just removing them can have a significant impact on your health. The question becomes then the so what will stopping this stuff now lower your risk? And the answer is yes. It just depends on where you're at in your life lifespan. What we know from smoking literature is that if you quit smoking within 10 years, your risk for lung cancer goes, goes back to, doesn't quite match, but goes close to your age matched normal. So that means if you're at say 50, you quit smoking when you're 60, your risk for lung cancer is about the same, not quite about the same as a 60 year old who didn't smoke. So the point is like making these changes now can have a profound impact on your risk for cancer.
