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.
