Experts advise: Start colorectal screening at 45, not 50

The guidelines are a response to a decades-long rise in diagnoses among younger Americans

SCREEN TIME  A colonoscopy, which involves inserting a long, flexible tube with a video camera at the tip into the rectum, is one of six tests the American Cancer Society suggests to screen for colorectal cancer. The group now recommends screening begin at age 45.

Colorectal cancer screening should begin at age 45 rather than 50, according to new guidelines released May 30 by the American Cancer Society. The recommendation is a response to the steady rise over decades in the colorectal cancer rate in younger Americans (SN: 4/1/17, p. 5).

For people at average risk for colorectal cancer — those without a personal or family history of the disease and who haven’t had inflammatory bowel disease — the ACS suggests regular screening begin at 45 with either stool-based tests or visual exams, such as a colonoscopy. The new ACS guidelines, published in CA: A Cancer Journal for Clinicians, equally endorse six possible screening methods.
