CA-125

CA 125 (Cancer Antigen 125)

A CA-125 test measures the amount of the cancer antigen 125 (CA-125) in a person’s blood. CA-125 is a protein that is a biomarker or tumor marker. It is found in greater concentration in cancer cells, particularly ovarian cancer cells.

Cancer types that can cause higher than normal levels of CA-125 include:

• Ovarian cancer
• Endometrial cancer, Fallopian tube cancer
• Pancreatic cancer
• Stomach cancer
• Esophageal cancer
• Colon cancer
• Liver cancer
• Breast cancer
• Lung cancer

Cancers that have spread to the peritoneum (the abdomen's lining)

The CA-125 test helps doctors:
Monitor ovarian cancer and other cancers to determine if they are responding to treatment Monitor patients with ovarian and other cancers post-treatment to check for cancer recurrence To an extent, screen for ovarian cancer in women who are at high risk for developing the disease.
