Definition

An adenoma is a benign tumor developed at the expense of a gland (testicle, breast, kidney, stomach) or of certain glandular mucus membranes (colon, rectum, uterus...). An adenoma is particular in that it copies the appearance and the structure of the gland on which it develops. Generally not dangerous in itself, it can still cause a cancerous tumor to form: an adenocarcinoma. The bigger the adenoma is, the more elevated the risks of it developing into adenocarcinoma are. In certain cases, surgical removal of the adenoma for preventative measures is advised.
