Unfortunately, there is no accurate screening test for ovarian cancer. It is important to familiarize yourself with the common ovarian cancer symptoms. If symptoms persist daily for 2 weeks or longer, you should speak to your doctor. Every woman should undergo an annual rectal and vaginal pelvic examination. If an irregularity of the ovary is found, alternatives to evaluation include transvaginal ultrasound and/or tumor markers. The most common tumor marker is a blood test called the CA-125.
