Advances in fertility preserving surgery for borderline ovarian tumors

Borderline ovarian tumor is a tumor with pathomorphological characteristics, biological behavior and prognosis between benign and malignant tumors. Preoperative diagnosis of ovarian cancer is usually based on imaging and tumor markers. Because of the early diagnosis and good prognosis of borderline ovarian tumors, fertility preserving surgery can be selected for patients with borderline ovarian tumors who have not completed fertility. Compared with radical surgery, fertility preserving surgery has a higher recurrence rate, but most of them are not malignant, which will not affect the overall survival rate, and the postoperative fertility rate is also very good. Patients with borderline ovarian tumors, especially those with BOT stage II or above, should get pregnant as soon as possible and be followed up closely for a long time.
