Ovarian cancer is a type of cancer that begins in the ovaries. Ovarian cancer is the most common type of cancer among women. Epithelial tumor, stromal tumor and germ cell tumors are the type of ovarian cancer. Pelvic discomfort, abdominal pressure, urinary urgency, swelling, low back pain, loss of appetite, change in bladder habits and lack of energy are some of the sign and symptoms for the ovarian cancer. Ovarian cancer is diagnosed with the help of pelvic examination, blood test, ultrasound and other tests such as MRI, PET and CT. Lack of early warning symptoms and early diagnostic tests for detection are the major causes of high rate of death due to ovarian cancer. It is one of the common causes of cancer death in women. According to World Cancer Research Fund International, in 2012, 239,000 new cases of ovarian cancer were detected. Globally, it constitutes about 1.7% of all cancer cases in 2012. Inherited gene mutation, estrogen hormone replacement therapy, polycystic ovary syndrome and fertility treatment may increase risk of ovarian cancer. Some of the complications in ovarian cancer is it can spread to other organs such as abdominal cavity, pelvis and abdominal lymph nodes, bones, liver, brain and sac surrounding the lymph nodes. The treatment of ovarian cancer is based on the stage of the disease. The treatment includes surgery, chemotherapy, radiation and biological therapy. Ovarian cancer is most chemo-sensitive cancer. The chemotherapy drugs are more effective when given in combination with radiation therapy.
