Cancerous and Benign Causes of Elevated CEA 125 Level. Dr Adil Ramzan. CEA 125 is an antigen that is expressed in the epithelial linings of the female genital tract, respiratory tract, cornea and conjunctiva. It is encoded by the MUC 16 gene (Mucin 16 Gene). MUC 16 protein (CEA), is a complex molecule, heavily glycosylated and easily water ...

What Are the Causes of Elevated CEA? Elevated carcinoembryonic antigen is caused by conditions such as cancer, pancreatitis, smoking infections and cirrhosis of the liver.

When used along with imaging studies and other tests, it can be helpful in planning and monitoring treatment. The test has limitations in that not all cancers (especially early stage cancers) have elevated levels, and false positives may occur, as many benign conditions may cause elevations in CEA.

To me either the level of CEA is totally unrelevant in term of cancer diagnosis in a non-diagnosed and asymptomatic person, and in that case there is no point to put a threshold on what is supposed to be normal, and more especially on what is too high to be benign, either there is effectively a level of CEA beyond what benign conditions are ...

CEA levels are elevated in 70% of patients with chronic liver disease and 50% of patients with acute liver disease. Elevated levels are also frequently seen in other gastrointestinal diseases including peptic ulcer, pancreatitis, diverticulitis, and inflammatory bowel disease. Benign diseases rarely produce CEA serum levels >10 ug/L.
