CA 125 is a glycoprotein antigen normally expressed in tissues derived from coelomic epithelia (ovaries, fallopian tubes, peritoneum, pleura, pericardium, colon, kidney, and stomach). Serum CA 125 is elevated in about 80 percent of women with advanced epithelial ovarian cancer, but elevated levels have also been associated with endometriosis.
