What is the CEA Test?
CEA (Carcinoembryonic Antigen) is a tumour marker primarily used for monitoring colorectal cancer treatment and detecting recurrence. Elevated CEA can also occur in cancers of the lung, breast, pancreas, and stomach. It's not specific enough for screening but is valuable for tracking known cancers.
Why Should You Take This Test?
Rising CEA after colorectal cancer treatment may indicate recurrence. Not used for initial diagnosis—colonoscopy and biopsy are diagnostic.
