Yolk cyst tumor is a relatively rare ovarian malignant tumor with a relatively small likelihood of not recurring in a lifetime, although survival is now significantly prolonged by surgery and combination chemotherapy. Yolk sac tumor is a malignant tumor, relatively rare, can account for about 1% of ovarian malignant tumors, common in children and young women. This disease has a high degree of malignancy, rapid growth, and is prone to early metastasis. However, yolk sac tumor is very sensitive to chemotherapy, so now after surgery and combined chemotherapy, the patient’s survival is significantly prolonged. If it is determined that it is a yolk cystic tumor, women who do not have childbearing requirements can undergo a fully staged surgery. If the patient is a young woman with fertility requirements, she can undergo surgery to preserve her fertility. However, this disease is prone to recurrence, so if it recurs, surgery is required. After surgery, chemotherapy is usually needed. After the treatment of yolk sac tumor, even if there is no discomfort, it is necessary to go to the hospital for regular checkups, mainly for ultrasound examination of the reproductive system.
