Nutritional supportive therapy and regular monitoring of the condition are needed after the detection of the disease; if the nodules have pain symptoms, oral aspirin and fenbendazole can be used for pain relief. 2. Thyroid cancer: it is a malignant tumor of the thyroid gland, which will cause extensive lymphatic metastasis when the tumor gradually increases in size. After diagnosis, surgery should be performed as soon as possible, and total or subtotal thyroidectomy should be performed. After surgery, iodine 131 treatment should be given, and levothyroxine tablets should be used as replacement therapy according to the condition. 3. Hyperthyroidism: that is, hyperthyroidism, mainly due to the thyroid gland hormone secretion of the formation of excessive thyroid nodules, can form the thyroid lymph nodes enlarged.
