Single thyroid nodule 2mm*3mm size, how to treat

A single thyroid nodule 2mm*3mm is not serious, usually benign, but the patient needs to go to the endocrinology department of the hospital for examination. If it is diagnosed as hyperthyroidism, antithyroid hormone treatment can be taken; the patient also needs to go to the hospital for regular reexamination. If the thyroid nodule increases, surgical resection can be selected.
