Glossary Term:


adenomatous polyp


ad-<b>no</b>-muh-tus or <b>ad</b>-uh-<b>NO</b>-muh-tus<b> pa</b>-lip


a benign (not cancer) growth made of abnormal glandular cells. These can become cancer, so they are usually removed when found. For example, 3 types of adenomas that can grow in the colon are tubular, villous, and tuberovillous. In each type, the cells are arranged differently, but there is some overlap so that an adenoma can have both tubular and villous features. See also glandular cells, hyperplastic polyp, inflammatory polyp, polyp, tubular adenoma, tubulovillous adenoma, villous adenoma.
