Ovarian cancer is one of the common gynecological malignancies in women. In the early stages, symptoms are not common and are not severe. The typical symptoms mainly manifest as pain and discomfort in the lower abdomen, and some patients may feel bloating in the lower abdomen. Some patients experience an increase in vaginal discharge, some have vaginal drainage or abnormal vaginal bleeding, and others may observe abnormal changes in their menstrual cycle, such as prolonged periods or increased menstrual flow, while some may experience reduced menstruation. Besides these, there are no other symptoms in early-stage ovarian cancer patients. As the disease progresses, the patient's abdominal pain and bloating will significantly worsen, indicating that the disease has advanced to the middle or late stages.
