Ovarian cancer may recur two years after surgery. In clinic, the recurrence time of ovarian cancer is related to the stage of ovarian cancer, pathological staging and residual lesions after surgery. For early-stage ovarian cancer patients, if the treatment is timely, surgical resection is thorough and the pathological staging is good, the time of recurrence is usually later. However, for patients with advanced ovarian cancer, with lower degree of pathological differentiation, incomplete resection of lesions during surgery, etc., the time of recurrence will be earlier, and it may recur in about 1~2 years. Therefore, patients suffering from ovarian cancer need to do early detection and early treatment, follow the doctor’s instructions during the treatment and keep a good mindset after the treatment, which will have a certain effect on reducing the recurrence rate.
