“Ovarian cancer is a type of cancer that begins in the female reproductive organs that produce and store eggs (ovaries). It occurs when abnormal ovarian cells divide and multiply uncontrollably. “Ovarian cancer” is a generic term for any primary malignant ovarian tumor. However, ovarian cancer is not one disease. There are many types of ovarian cancer, including some that are extremely rare and require specialized treatment. Therefore, establishing the correct diagnosis upfront is very important. The main types of ovarian cancer are named for the cells where the disease first forms. There is epithelial ovarian cancer, germ cell ovarian cancer, stromal ovarian cancer, and primary peritoneal ovarian. ”
