Several diagnostic tests diagnose rectal cancer. Sigmoidoscopy and colonoscopy are exams in which your doctor inserts a tube into your rectum in order to see the inside of the colon. Another test that enables your doctor to view your colon is a barium enema exam, in which your doctor injects a barium solution into your rectum. The barium makes your colon visible during an x-ray, and your doctor can see if there are any abnormalities in the intestinal lining. Sometimes a CT scan is used to diagnose rectal cancer and to determine if the cancer has spread to other parts of the body. The stage of your cancer may not be known until it is surgically removed.
