Each year, about 22,000 women in the United States are diagnosed with ovarian cancer. The symptoms of ovarian cancer are often common and vague, which makes it difficult to diagnose.
There are more than 30 different types of ovarian tumors, which are categorized according to the cell type. Some are benign (noncancerous) and do not spread beyond the ovary. Malignant (cancerous) tumors can spread to other parts of the body.
Currently, there is no effective early detection method for ovarian cancer. It is usually diagnosed in advanced stages, and only about half of women survive longer than five years after diagnosis. For the 25% of ovarian cancers that are found early, the five-year survival is greater than 90%.
Studies have shown that prognosis and survival depend largely on how much tumor is left at the time of initial surgery. Patients who have no remaining tumor or with only nodules less than one centimeter in diameter have the best chance for cure and long-term survival.
