Sessile polyps simply mean that the mass is flat and does not have a stalk. The other types of colonic polyps are pedunculated- these are not flat but attached to a stalk. Since a sessile colonic polyp does not have a stalk, it is usually found very close to the colonic wall lining.
Growth=Polyp=Tumor: A growth in the colon, also called a polyp, is a tumor or growth of abnormal tissue. They can be benign (non-cancerous) or cancer. Benign polyps such as adenomas have potential to turn to cancer if they grow a long time.essile = flat: Sessile polyps are flat, which makes it very difficult (but not impossible) to remove. However, they can usually be biopsied to determine if (pre)cancerous or not. This is where the gastroenterologist comes in handy.
