Gastrointestinal cancers, which include colorectal, stomach and pancreatic cancer, are rising dramatically in younger adults, though doctors aren’t fully sure why. Even some of the possible causes require more research, they say.

According to a review published Thursday in JAMA, gastrointestinal cancers have become the fastest-growing type of cancers diagnosed in adults younger than 50 in the U.S.

The review, one of the most comprehensive looks at gastrointestinal cancer trends, summarized the findings of major international and U.S. cancer databases, plus 115 papers on gastrointestinal cancers published from January 2014 to March 2025.

    My guess is some combination of PFAS, micro plastics, glyphosate sprayed all over our “roundup ready” GMO crops (namely corn which is in fucking everything), and chemical additives to the food.

      No. It’s because a massive amount of us don’t move around anymore, eat shit for food and are obese. This article lays it out pretty well. I don’t know why this is a mystery. We’re fatter than ever, we move less than ever, we drink more than ever, and we eat like shit. This isn’t rocket science. Lose the weight, move, eat healthier, and stop drinking in excess. Otherwise keep doing it and have a hogh risk of cancer at a early age.

      Most early-onset GI cancers are associated with modifiable risk factors including obesity, poor-quality diet (eg, sugar-sweetened beverages, ultraprocessed foods), sedentary lifestyle, cigarette smoking, and alcohol consumption.
