A polyp is a projection (growth) of tissue from the inner lining of the colon into the lumen (hollow center) of the colon.
Polyps that tend to grow as slightly flattened, broad-based polyps are referred to as sessile. Serrated polyps are polyps that have a saw tooth appearance under the microscope.
