What the CA-125 Test measures
Cancer antigen 125 (CA-125) can rise with ovarian cancer, but also with many common, non-cancerous conditions such as menstruation, endometriosis, fibroids, pregnancy and pelvic infections, so a raised level needs careful interpretation.
Why it's done
- Monitoring treatment response or recurrence in people already diagnosed with ovarian cancer, on medical advice
- Providing additional context alongside imaging ordered by a specialist
How to prepare
No fasting is needed — eat and drink normally. Wear something with sleeves that roll up easily, and keep a list of any medicines you take handy for your phlebotomist.
Understanding your result
CA-125 is not reliable as a stand-alone screening test for ovarian cancer, since many benign and everyday conditions can raise it, especially in people who menstruate. A raised result should be discussed with your doctor, who will weigh it against your symptoms, imaging and history.
Frequently asked questions
Can CA-125 screen for ovarian cancer?
It is not recommended as a general screening test, since common conditions can raise it without cancer being present. It is mainly used for monitoring in people already diagnosed, on a doctor's advice.
What else can raise CA-125 besides cancer?
Menstruation, endometriosis, fibroids, pregnancy and pelvic infections can all raise CA-125, which is why it is interpreted alongside your symptoms and history.
