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.
Polyps are abnormal growths of tissue that can be found in any organ that has blood vessels. They are most often found in the colon, nose, or uterus.
