A lump in the neck is most commonly a thyroid disease, mainly nodular goiter, but also simple thyroid adenoma or thyroid cyst, which occurs with obvious regional structural differences, and is more common in middle-aged and old-aged patients, and is considered to be related to imbalance of thyroxine metabolism and lack of iodine in food. Patients may present with neck swelling, which may be accompanied by painful symptoms. With the development of the disease, the tumor gradually increases in size, which may also lead to tracheal compression, and patients may have obvious chest tightness and palpitations, which are aggravated after activities. In this case, surgical treatment should be chosen in time, which can be operated under local anesthesia or general anesthesia, and the lesion will be removed or partial resection of the thyroid gland will be chosen. After the operation, you should also pay attention to the whole liquid diet, avoid strenuous activities, change the medication regularly, and review the ultrasound of the thyroid gland regularly.
