CA125 - Ovarian & Uterine Cancer Marker
A CA-125 blood test is most often done on women already diagnosed with ovarian cancer. It can help find out if cancer treatment is working, or if your cancer has come back after you have finished treatment. CA-125 levels are high in many women with ovarian cancer. High CA-125 levels can be a sign of other conditions besides ovarian cancer.
If you are not being treated for ovarian cancer and your results show high CA-125 levels, it can be a sign of cancer. But it may also be a sign of a noncancerous condition, such as:
- Adenomyosis
- Benign ovarian tumours
- Endometriosis
- Pelvic inflammatory disease (PID)
- Uterine fibroids
- Liver disease
- Pregnancy
- Menstruation
