The American Cancer Society updated its colorectal cancer screening guidelines to recommend that average-risk adults begin screening at age 45. The organization also added blood-based tests as an accepted screening method alongside existing options such as colonoscopy and stool-based tests.

The change aligns the society’s guidance with current medical practice at many health systems that already begin screening at 45.
