Cancer Antigen 125 (CA-125)

CA-125 can rise with ovarian tumours, and also with many benign conditions such as endometriosis, cysts and the period itself.

Doctors read it with ultrasound and examination and use it mostly for follow-up.

Preparation before the test

• No fasting needed; it can be done any time.
• Best done away from period days.
