Epithelial ovarian cancer cannot be cured and has a high chance of recurrence. Epithelial ovarian cancer is a common type of ovarian cancer, which is commonly found on the surface of the ovary and has no obvious symptoms in the early stage. However, if it is detected at an early stage, the relative quality of survival is still very high, but if it is already in the middle or late stage after detection, the relative quality of survival is very low. In general, after detection, surgery is required to remove the tumor, pelvic lymph node dissection and tumor cell reduction, and adjuvant chemotherapy and radiotherapy are given after surgery, and biological immunotherapy can also be adopted. However, no matter which treatment method is used, it can only prolong the life of the patient but not cure.
