  A glycoprotein, mol. wt. 2000,000, secreted into the glycocalyx coating the luminal surface of gastrointestinal epithelia. Originally thought to be a specific antigen of the fetal digestive tract and adenocarcinoma of the colon. CEA is now known to occur normally in feces and pancreatico-biliary secretions and to appear in the plasma in a diverse group of neoplastic and non-neoplastic conditions including cancers of the colon, pancreas, stomach, lung, and breast, alcoholic cirrhosis and pancreatitis, inflammatory bowel disease, rectal polyps, and cigarette smoking.
