A new expert commentary from the American Gastroenterological Association focuses on noninvasive screening options for colorectal cancer (CRC), as well as approaches to ensure quality in noninvasive screening programs. The commentary was published in Gastroenterology.
The American Cancer Society reported in its Cancer Facts & Figures 2021 report that lifetime risk of CRC in the United States is 4%, and those with above average risk are recommended to undergo CRC screening at an earlier age, with colonoscopy as a screening modality. Between 75% and 80% of the U.S. population is considered at average risk, and this is the group covered by the expert commentary. In this group, CRC rates jump from 35.1 to 61.2 cases per 100,000 people between the ages of 45-49 years and 50-54 years. Early-onset (before 50) CRC accounts for 12% of all cases and 7% of CRC-related deaths.
