The majority of thyroid tumors are benign. For smaller benign tumors, regular follow-up (3 months-6 months) is usually sufficient without medication or active surgery. Only benign tumors are larger, compressing the trachea and esophagus causing difficulty in breathing and swallowing, tumors falling into the back of the sternum, complicating hyperthyroidism or affecting appearance and psychology. Surgery is preferred for malignant thyroid tumors. After surgery, some patients can be supplemented with nuclear hormone therapy (iodine 131) and endocrine drug therapy (eugenol), and chemotherapy and radiotherapy are basically unnecessary.
