? Malignant thyroid nodules usually have no obvious symptoms in the early stage. However, thyroid nodules will swell rapidly in a short time, resulting in thickening of the neck. Swelling is usually irregular, will adhere to the surrounding tissues, unclear boundaries, will move with swallowing, but will not move in the later stage. When the nodule swells and moves, we must pay attention to it, which may be a symptom of malignant transformation of the nodule. In addition, in ATC examination, it can be found that the swelling gradually increases and develops rapidly, which will involve the surface in the later stage and make the skin appear dark red.

? Second, thyroid dysfunction.

? Under normal circumstances, some patients with thyroid nodules will have hyperthyroidism or hypothyroidism in the later stage, which is caused by the decrease of thyroid hormone synthesis and secretion or the lack of its physiological function. According to its etiology, it can be divided into primary hypothyroidism, secondary hypothyroidism and peripheral hypothyroidism. Toxic thyroid nodules secrete too much thyroid hormone, which leads to the clinical manifestations of hyperthyroidism. The typical symptoms of hyperthyroidism are hunger, overeating, fear of heat and sweating, damp and hot skin, palpitation, weight loss and so on. Some patients show a low fever.

? Third, hoarseness.

? When the symptoms of hoarseness appear, many people mistakenly think that it is caused by excessive internal heat. If the situation does not improve after drinking Huocha, then it can be considered as a thyroid nodule. This is because the thyroid nodule will compress the recurrent laryngeal nerve, trachea and esophagus when its volume increases. In addition to hoarseness, dysphagia and dyspnea may occur, which is also caused by the increase of thyroid nodules.

? Fourthly, the local tumor moves up and down.

? Thyroid nodules will send signals in the process of affecting health, and many people will have local masses after the formation of thyroid nodules. In the process of swallowing food, the obvious symptom is that these lumps move up and down with the thyroid gland. If there are such obvious manifestations, it means that thyroid nodules already exist and need to be improved in the right way.
