Adenocarcinoma

Adeno- is a prefix which means “gland”. Adenocarcinoma is a cancerous tumor that starts in cells with gland-like properties (i.e. they have a secretory function) that line some internal organs. The majority of all breast, colon, and prostrate cancers are adenocarcinomas. Human pancreatic adenocarcinoma is the most lethal of all common cancers.
