The treatment of right ovarian teratoma 3.6cm can be surgical, radiotherapy or chemotherapy depending on the patient’s specific condition. 1. Surgical treatment: applicable to patients with mature teratoma and immature teratoma. (1) Mature teratoma can be treated with teratoma excision in young women and right adnexectomy in old women. (2) Immature teratomas need to be selected for surgery based on age and fertility requirements. For young women who do not have fertility requirements, the diseased parts and organs will be removed according to the specific degree of the disease. If the patient has fertility requirements, the uterus and the left normal ovary can be preserved. 2. Radiotherapy or chemotherapy: for immature teratoma. Immature teratoma belongs to malignant tumors, and the treatment cost will be better if combined with radiotherapy or chemotherapy along with surgical treatment. Teratoma on the right side of the ovary should be treated in a timely manner to avoid delay.
