Both polyps and colorectal cancers can bleed, and FOBT checks for tiny amounts of blood in feces (stool) that cannot be seen visually.How often should FOBT be done?
To allow for the early detection and prevention of colorectal cancer, the fecal occult blood test is recommended yearly for everyone starting at age 50.
