Kimmie Ng, M.D., a Boston oncologist, started noticing an alarming trend in her work a few years ago. 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, a family of diseases that can start in the colon or rectum and are typically associated with older people and those with risk factors like family history and obesity.
Colorectal cancers are the third-most-frequent type of new cancer in men (right behind prostate and lung). And while they're declining for older guys, the rates among younger Americans are on the rise. What doctors have been picking up on in their day-to-day work is only now being fully captured in medical research and in the news. In 2017, a large American Cancer Society-funded study of invasive colorectal cancers found that people born around 1990 have double the risk of developing colon cancer and quadruple the risk of developing rectal cancer compared with those born around 1950—a finding worrisome enough to prompt the ACS to lower its recommended screening age for people of average risk of colorectal cancers from 50 to 45. If the trend continues, a study in JAMA Surgery predicted, by 2030 the rate of colon cancer will rise by 90 percent and that of rectal cancer by a staggering 124 percent in people ages 20 to 34.
The great majority of early-onset colorectal cancers start in the rectum, the lowest part of the colon, which can be linked with symptoms like rectal bleeding and constipation, says Robin Mendelsohn, M.D., a gastroenterologist and researcher at MSK's Center for Young Onset Colorectal Cancer. If you're seeing blood in your stool or on the toilet paper; if you notice stools narrowing or changing consistency; or if you have nausea, stomach pain, or bloating—any new or odd symptom that lasts "more than a couple of weeks," she says—don't write it off. If you get pushback from your doc about testing—and you might, as up to 17 percent of early-onset colorectal-cancer patients are initially misdiagnosed, according to a recent Colorectal Cancer Alliance (CCA) survey—push right back. "When we catch these cancers early, we can treat them more effectively," Dr. Mendelsohn says.
More at the link. But um holy shit and right now they recommend people get checked at 45, but im just gonna say fuck it and get check starting this year and call my doc. This is extremely alarming. especially seeing what happened with Chadwick. Im extremely concerned.
