For ovarian teratoma, there is no effective preventive measure to stop it from growing; because the cause and pathogenesis of the disease are still unclear. Ovarian teratoma is a common tumor derived from germ cells, but there are benign and malignant tumors; teratoma patients have no obvious symptoms in the early stage, and as the tumor increases in size patients may have abdominal distension, abdominal pain, abdominal masses and other manifestations. The treatment of ovarian teratoma should be based on the type of pathology and take different treatment measures; if it is benign, surgical resection is usually enough; if it is malignant, after surgical resection, it needs to be combined with chemotherapy to control the condition. Malignant ovarian teratoma is prone to recurrence. Once the diagnosis of ovarian teratoma is confirmed, reasonable treatment measures should be taken under the guidance of the doctor, and attention should also be paid to regular review.
