Video: Who should be screened for colorectal cancer?

Colorectal cancer is the second-leading cause of cancer death in the U.S. The U.S. Preventive Services Task Force and the Multi-Society Task Force on colon cancer encourage patients to start screening at age 50 unless they have other risk factors like family history or inflammatory diseases that could predispose them to colon cancer. However, African Americans may consider getting screened at an earlier age. Dr. John Kisiel, a Mayo Clinic gastroenterologist, explains who is at risk.
