tubular adenoma


<b>tube</b>-yoo-ler<b> ad</b>-no-muh or<b> ad</b>-uh-<b>NO</b>-muh


a benign (non-cancerous) polyp made of gland cells formed into tubes, in which the tubular structure generally makes up more than 75% of the adenoma. They usually cause no symptoms, and are often found during screening procedures such as colonoscopy. Because they are pre-cancerous, they are generally removed when found. See also adenomatous polyp, colonoscopy, polyp, tubulovillous adenoma, villous adenoma.
