Ovarian cancer is the eighth most common cancer among women (after skin cancer) and the fifth leading cause of cancer deaths in women in the United States. The American Cancer Society estimates that about 20,000 new cases of ovarian cancer will be diagnosed this year, and approximately 15,000 women will die from ovarian cancer this year. Ovarian cancer is often called the silent killer because its symptoms can be subtle, leading to a delayed diagnosis and poorer outcome. However, if ovarian cancer is detected early, approximately nine out of ten women will live for at least five years with the disease.
