Colon Cancer in Young People Is on the Rise

For years, colorectal cancer wasn't a concern for those under the age of 50, but in 2018 the medical guidelines for colorectal cancer screening were changed, lowering the recommended age for the initial screening to 45.

Some adults assume they don't have to worry about colorectal cancer because they’re younger than 50. While this belief is based in some logic – 90 percent of incidences of the disease occur in those who have passed that age threshold – it makes the risky and ultimately incorrect assumption that colorectal cancer doesn't also strike younger people.

Since the mid-1990s, new cases of colorectal cancer in individuals aged 20 to 49 have been on the rise. Researchers estimate that by 2030, the incidence of early-age onset colorectal cancer will increase by over 140 percent, with more than 27,000 people under 50 diagnosed. The exact reason for the increase is unclear.

Regardless of age, adults in the U.S. should be aware of their risk factors for colorectal cancer and should be taking proactive steps to prevent it, such as changing diet, quitting smoking, and getting more exercise. If you’re unsure of your risk, talk to a doctor about your family history of cancer and current lifestyle, including diet.
