Polyps are small growths that develop in the tissue lining inside some organs. They can develop in two main shapes. Sessile polyps grow flat on the tissue lining the organ and can blend in with the lining of the organ, so they’re sometimes tricky to find and treat. According to Healthline - Sessile polyps are considered precancerous. They’re typically removed during a colonoscopy or follow-up surgery.
