Colonoscopy is used to view the inside of your lower digestive tract (colon and rectum). It can help screen for colon cancer and can also help find the source of abdominal pain, bleeding, and changes in bowel habits. The test is usually done in the hospital on an outpatient basis. During the exam, the doctor can remove a small tissue sample ( a biopsy) for testing. Small growths, such as polyps, may also be removed during colonoscopy.

A colonoscopy is an examination of your entire colon. For it, your doctor uses a small video camera that's attached to a thin tube called a colonoscope. The camera sends images to a small TV screen, and your doctor can see if anything looks unusual. If your doctor finds a small polyp during the test, he or she can remove it and send it to a lab for testing to see if it is cancerous. The removal of tissue is called a biopsy. Your doctor will take a biopsy of a tumor, large polyp, or anything else abnormal that's found.

Sometimes cancers or polyps bleed. An FOBT checks for blood in your stool. It's a highly sensitive test, which means it can find polyps and cancer. However, sometimes the test can indicate that there's a polyp or cancer when there isn't. This is called a false positive. Or it can miss a polyp that doesn't bleed. Therefore it's commonly used as an initial test before another screening test such as a colonoscopy or a sigmoidoscopy.
