Polyps are small growths on the inside of the colon. 10% of people who have colonoscopy are found to have polyps. If small they usually cause no symptoms. As they grow they can bleed. Polyps have the potential to turn into cancer. When found they are usually removed to prevent cancer in the future.
Polyps are usually removed during your colonoscopy. Some larger polyps may be left if the best method of removal is not clear. Removal involves placing a wire around the polyp and removing it.
Polypectomy increases the risk of perforation and bleeding. However the risk is still small. The risks will be discussed at the initial consultation and again prior to the procedure during the consent process.
