What are polyps and why or how are they removed?

Polyps are abnormal growths in the lining of the colon that are usually benign (noncancerous). They can occur in several locations in the gastrointestinal tract, but are most common in the colon. They vary in size from less than a quarter of an inch to several inches in diameter. They look like small bumps and some are flat. Your GI doctor will have them analyzed. Removing polyps is an important means of preventing colorectal cancer. Usually your GI doctor removes the polyp with a wire loop through the colonoscope using an electrical current. You will have been sedated and will feel no pain.
