CA 125 Antigen
CA 125 Antigen is a heterogonous glycoprotein. It can be detected in ovarian cancer. Moderately elevated values may be detected in patiens with other malignancies (e.g. cancer of pancreas, breast, lung, stomach or colon) or in non-malign conditions such as inflammation of serous membranes, ovarian cysts, cirrhosis or endometriosis. CA 125 determination is used mainly for diagnosis and monitoring of ovarian cancer.
