What is a CEA CARCINO EMBRYONIC ANTIGEN?

The Carcinoembryonic Antigen (CEA) test is a blood test that measures levels of CEA, a protein normally present at very low concentrations but often elevated in certain cancers, especially colorectal cancer. It is primarily used to monitor treatment effectiveness, detect recurrence, and sometimes assist in diagnosis when cancer is suspected. While not specific enough for general cancer screening, it is a valuable tumor marker for patients already diagnosed or at high risk, guiding oncologists in clinical management.
