Screening for Ovarian Cancer.

Ovarian cancer is difficult to manage because the disease is most often diagnosed at an advanced stage when survival chances are poor. Early detection of ovarian cancer would increase long-term survival, since effective treatment modalities are available for early-onset disease. Screening with transvaginal ultrasound and serum CA 125 suggests promising results, but studies comparing mortality rates for screened vs unscreened populations are needed, and strategies must be developed for prevention or early diagnosis in order to control this disease process.
