tumour marker

Any specific substance present in increased amounts in serum that may be used for early cancer (CA) detection. Most tumour markers are nonspecific and of little use as screening tools; they may be used to detect recurrence (e.g., CEA in patients with known colorectal and other CAs).  

Examples
Oncofoetal proteins (alpha-fetoprotein) for hepatic carcinoma; CA125 for ovarian CA; CEA for ovarian, lung, breast, pancreas, GI tract CAs; PSA for prostate CA.
