The CEA Test is a blood test that measures the level of carcinoembryonic antigen (CEA), a protein that may be elevated in certain cancers, particularly colorectal cancer. It is primarily used for monitoring cancer progression, treatment response, and recurrence, rather than for initial diagnosis.
Why is the CEA Test Done?
✅ Monitor colorectal cancer – Helps track cancer progression and treatment effectiveness.
✅ Detect recurrence – Used after treatment to check if cancer has returned.
✅ Assess other cancers – Can be elevated in lung, breast, pancreatic, and ovarian cancers.
✅ Evaluate tumor burden – Higher levels may indicate larger or more advanced tumors.
