Why Get Tested?

To monitor treatment for ovarian cancer or to detect recurrence; sometimes to evaluate a lump located in the pelvic area (pelvic mass); not recommended for screening asymptomatic women but sometimes ordered to help detect early ovarian cancer in those identified as being at high risk.

Before starting therapy for ovarian cancer and at intervals during and after treatment; sometimes when you have a pelvic mass or are at a high risk for developing ovarian cancer.
