If the doctor sees an area that needs evaluation in greater detail, a biopsy (sample of the colon lining) may be obtained and submitted to a laboratory for greater analysis. If polyps (growths from the lining of the colon which vary in size) are found, they can be biopsied, but usually are not removed at the time of the sigmoidoscopy. Polyps are of varying types; certain benign polyps, known as “adenomas,” are potentially precancerous. Certain other polyps (“hyperplastic” by biopsy analysis) may not require removal. Your doctor will likely request that you have a colonoscopy (a complete examination of the colon) to remove any large polyp that is found, or any small polyp that is adenomatous after biopsy analysis.
