CEA – Carcino Embryonic Antigen, Serum
CEA-CARCINO EMBRYONIC ANTIGEN in Delhi NCR
Carcinoembryonic antigen (CEA) is a glycoprotein involved in cell adhesion. It is normally produced during fetal development, but the production of CEA stopsbefore birth. Therefore, it is not usually present in the blood of healthy adults, although levels are raised in heavy smokers. The carcinoembryonic antigen (CEA)test measures the amount of this protein that may appear in the blood of some people who have certain kinds of cancers, especially large intestine (colon andrectal) cancer. It may also be present in people with cancer of the pancreas, breast, ovary, or lung. Elevated serum CEA levels have also been detected inpatients with non-malignant disease, especially patients who are older. CEA levels are not useful in monitoring the course of disease. CEA levels generally fall tonormal or near normal levels within one to four months after surgical removal of cancerous tissues. A rise in CEA levels may be first indication of recurrence andmay precede physical science symptoms.
