Ovarian cancer is the deadliest type of female reproductive cancer with it being the most common in postmenopausal women. Women who have a family history or specific inherited gene changes have a higher risk of developing ovarian cancer. There are multiple types of this cancer that are treated the same way including ovarian epithelial cancer, fallopian tube cancer, and primary peritoneal cancer. Since ovarian cancer often does not show symptoms, it can be hard to diagnose this cancer early. Some of the other risk factors for ovarian cancer include hormone replacement therapy, weight and height, and endometriosis. But some protective factors include oral contraceptives, giving birth, or salpingectomy.
