CA 125 Index

Featured: CA 125 Main Article

CA 125 is a protein, and a tumor marker or biomarker. CA 125 is present in greater concentration in ovarian cancer cells than in other cells. CA stands for cancer antigen. Increases in CA 125 can also occur with malignant tumors of the Fallopian tubes, lining of the uterus, lung, breast, and gastrointestinal track. Benign conditions such as infections of the abdomen, chest, menstruation, endometriosis, benign tumors of the ovaries, and liver disease can also raise CA 125.
