The incidence of thyroid tumors is increasing, especially in women, and people often feel overwhelmed after the onset of the disease: they are not willing to have surgery, but they are worried about growing malignant tumors if they do not have surgery. From the current post-surgical pathology, only a small percentage of patients have true thyroid cancer. A significant proportion of patients have nodular goiter, which has a high chance of recurrence even after surgery. When is surgery recommended? 1. Imaging tests (ultrasound, CT) suggest the possibility of malignancy; 2. Rapid growth of nodules; 3. Seriously affects the aesthetics or life; 4. Retrosternal goiter; 5. Combined hyperthyroidism; 6. Strong psychological burden and strong request for surgery. If you do not meet the above conditions, you can take medication to control and review regularly: you can take eugenol or thyroxine tablets to control TSH at low normal level; review ultrasound and thyroid function every 3-6 months. It should be noted that taking medication does not make the nodules disappear, but only controls the development. If the above-mentioned 6 changes occur during medication, surgery should be performed as soon as possible.
