List of Colon Cancer Tests Expanded

Medical groups now endorse more types of tests to screen people for colon cancer. The purpose is to encourage more people to get tested. The new guidelines were issued March 5. They come from the American Cancer Society and several groups of doctors. For the first time, virtual colonoscopy is recommended. This test uses a form of X-ray. Also new is a stool DNA test to look for colon cancer. There are five standard tests as well. Colonoscopy and sigmoidoscopy use a tiny camera to look inside the colon. A barium enema test uses a contrast dye to enhance X-rays. Two tests look for blood in the stool. They require follow-up tests. The Associated Press reported on the guidelines March 6.
