tl;dr: we don't know yet.

If I had to guess, I'd say microplastics or some dietary thing like aspartame.

But there's also a link between colon cancer and running. The article mentions two people as pictures of health who run a lot.

Men in their 20s, 30s, and 40s—runners, CrossFitters, lifelong nonsmokers—were streaming through her door at the Dana-Farber Cancer Institute. They all appeared lively and strong—yet there they were, battling colorectal cancers

Well there's your problem. Don't run, drink beer with friends, smoke socially and you'd happily get to retirement! 🤭

Not enough fiber. Everyone eating carnivore diets and nobody eating fibrous foods

F. nucleatum animalis. Cancer causing bacteria. No l, there's not much you can do. Results of the 2024 study by Nature.

Mine went from zero to stage 2 in 6 months, no family history, no genetic pre-disposition. Surgery 1 week from today.

March is colon cancer awareness month, get checked and wear blue.

Pro-tip, the stuff they make you drink before hand is NASTY. It tastes like salt water and not even GOOD salt water, salt water made with that fake potassium salt.

But if you add Gatorade powder (lime or arctic cherry, green or white drinks only, no orange or red) it's drinkable. One glass every 12 minutes for 2 hours, wait 6 hours and do it again:

Colonoscopy itself is no big deal, you're out for the whole thing!

Definitely need more research. I was diagnosed at 36 and had no genetic predisposition. Doc said I was just "unlucky."

Let me guess it's all the "food" we eat

I'm curious if as kids they loved the sour candy stuff popular during their youth, could there be a connection or correlation?

If youre nervous about colonoscopies there are alternatives out there. Tests like Cologuard are much less invasive. They are not 100% accurate, but something is better than nothing when it comes to colon cancer.

As long as it’s not getting railed up there causing it, I’m happy.

Good article. I remember reading one from a major publisher that basically said "we don't know", which is nonsense.

One of the most intriguing leads is the microbiome, the diverse, teeming community of microorganisms living within us. Among the few things we know is that it’s constantly evolving. Some changes could “result in a benefit or insult to surrounding cells,” notes Dana-Farber physician and scientist Marios Giannakis, M.D., Ph.D. That means the microbiome may affect cells it touches and possibly play into the development of disease.

Researchers are looking into anything that could be changing the microbiome and affecting these cancers. Right now they know that what you eat and what meds you take are at least part of it. Killing off bacteria with antibiotics can upset the microbiome’s balance. So may eating too much added sugar. (Aim for 36 grams a day max for general health.) “With anything that modulates the microbiome,” says Dr. Giannakis, “there’s an open question as to whether it’s good or bad. We just don’t know yet.” A new five-year, $25 million study led by Dana-Farber researchers aims to tease out some answers.
