Should I be screened for colorectal cancer?

Most adults 50 and older should be screened for colorectal cancer. Adults at very high risk for colorectal cancer should begin screening earlier than age 50. Several effective screening tests are available including the cards that test for blood in the stool (a "fecal occult blood test" or FOBT), sigmoidoscopy, and colonoscopy. Ask your doctor when you should start screening and which test is right for you. People between the ages of 76-85 should talk to their doctor to see if screening is still needed. People over 85 do not need to continue screening.
