Bleeding
Both intermenstrual bleeding and rectal bleeding could be signs of ovarian cancer. Many factors can cause intermenstrual bleeding or bleeding between periods. Intermenstrual bleeding is often associated with hormonal imbalance and infections. However, intermenstrual bleeding, especially if accompanied by rectal bleeding, can be an early sign of ovarian cancer. If you have been experiencing vaginal or rectal bleeding, immediately set up an appointment with your doctor. [5]
