When microscopic thyroid cancer is diagnosed, it should be treated surgically by total excision of the affected gland and, if necessary, most of the healthy gland. After surgery, the thyroid gland should be monitored regularly. If there is significant hypothyroidism, thyroid hormone replacement therapy should be administered, such as oral Eugenol tablets. During the treatment period, attention should also be paid to increasing dietary nutrition, appropriate physical function exercises, but not strenuous, and appropriate iodine-containing foods can be supplemented in general, but not too much. In addition, you should supplement with high-protein food and high-calorie food, eat more fresh vegetables as well as fruits, and review the neck ultrasound once a year and perform enhanced CT examination of the neck if necessary to exclude metastasis.
