Digestive Disorders

Tubular Adenoma



Please explain tubular adenoma. This is the result of my colonoscopy.


A tubular adenoma is a type of colon or rectal polyp. A polyp is a benign growth or tumor that develops on the inside lining of the colon. Polyps of the adenoma-type are thought to be the precursors of colon cancer and therefore if one is found during a colonoscopy it is removed. The presence of an adenoma indicates an increased risk for the development of further adenomas or cancer and thus patients who are found to have them should have a follow-up colonoscopy in the future. The number, size, and histology (ie. microscopic appearance) of colon adenomas determines the risk and frequency of follow-up needed.
