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