Colonoscopy is a procedure that enables an examiner (usually a gastroenterologist) to evaluate the inside of the colon (large intestine or large bowel). The colonoscope is a four foot long, flexible tube about the thickness of a finger with a camera and a source of light at its tip. The tip of the colonoscope is inserted into the anus and then is advanced slowly, under visual control, into the rectum and through the colon usually as far as the cecum, which is the first part of the colon.

Colonoscopy may be done for a variety of reasons. Most often it is done to investigate the cause of blood in the stool, abdominal pain, diarrhea, a change in bowel habit, or an abnormality found on colonic X-rays or a computerized axial tomography (CT) scan. Individuals with a previous history of polyps or colon cancer and certain individuals with a family history of some types of non-colonic cancers or colonic problems that may be associated with colon cancer (such as ulcerative colitis and colonic polyps) may be advised to have periodic colonoscopies because their risks are greater for polyps or colon cancer. How often should one undergo colonoscopy depends on the degree of the risk and the abnormalities found at previous colonoscopies. One widely accepted recommendation has been that even healthy people at normal risk for colon cancer should undergo colonoscopy at age 50 and every 10 years thereafter, for the purpose of removing colonic polyps before they become cancerous.

A: Lipomas (benign tumors consisting of fat) are benign, that is, they are not cancerous. If the pathologist (the doctor who examines the polyp) is confident that the polyp is a lipoma, no further tests or surveillance will be necessary.

When to perform the next colonoscopy after removal of two non-cancerous, non-lipomatous polyps depends on several issues:...
