Colorectal cancer screening: An update to the American Cancer Society guideline, 2026

CA: A Cancer Journal for Clinicians, Volume 76, Issue 3, May/June 2026.
ABSTRACT Colorectal cancer (CRC) is a leading cause of cancer incidence and mortality in the United States, with rates recently increasing among adults younger than 65 years. In 2018, the American Cancer Society (ACS) lowered the recommended age to initiate screening for average‐risk adults to age 45 years.
