CEA (Carcinoembryonic Antigen)
CEA is a glycoprotein normally produced during fetal development that can be re-expressed by some cancers, especially colorectal carcinoma. It is used to monitor treatment response and detect recurrence rather than to screen, since it is also elevated in smokers, inflammatory bowel disease, liver disease, and other GI cancers. Rising CEA after surgery warrants imaging.
