The CA 72-4 Test is a blood test that measures the level of cancer antigen 72-4 (CA 72-4), a protein that is often elevated in individuals with gastric (stomach) cancer and other gastrointestinal cancers. It is mainly used for monitoring cancer progression, treatment response, and recurrence rather than for initial diagnosis.
Why is the CA 72-4 Test Done?
✅ Monitor stomach (gastric) cancer – Helps track cancer progression and response to treatment.
✅ Detect recurrence – Used after treatment to check if cancer has returned.
✅ Assess other cancers – Can be elevated in ovarian, colorectal, and pancreatic cancers.
✅ Aid in cancer diagnosis – Used along with other tumor markers (e.g., CA 19-9, CEA).
