Ovarian cancer is almost asymptomatic and hard to be detected in the early stage. Women should have regular gynecological checkups and if abnormalities are found, CT scan of the pelvis can be done to find out whether ovarian cancer is present, so that early detection and treatment can be done to avoid deterioration of quality of life and shortening of the patient’s life. Ovarian cancer will only cause pain in advanced stages, such as recurrent pain in the lower abdomen, lumbosacral pain and vulvar swelling, and other symptoms, such as fatigue and cachexia. In advanced ovarian cancer, if surgery is possible, surgery will be used as much as possible, mainly to remove the cancer, and then chemotherapy will be chosen according to the specific situation after surgery, which will prolong the patient’s life.
