With the increasing prevalence of thyroid disorders and the growing popularity of physical exams, many people can detect early thyroid problems, such as thyroid nodules, through physical exams. Thyroid nodules are a very common disease, especially among middle-aged women, and many patients with thyroid nodules detected during physical exams are concerned because of the possibility of cancer. It is understood that there are a variety of clinical thyroid diseases that can manifest as nodules, such as thyroid degeneration, inflammation, autoimmune and neoplastic, not necessarily thyroid cancer. Therefore, if there are “thyroid nodules” or “hypoechoic thyroid” in the physical examination report, there is no need to be alarmed, but consult a professional endocrinologist at a surgical clinic. If the physical examination report states the following, for example, “internal hypoechogenicity, often with gravelly, strong echogenic dots”, “uniform internal echogenicity, often with calcified dots in the tegument or nodule”, or “solid echogenicity with extra-thyroidal infiltrates”, then the nodule should be considered benign. The presence of a solid, irregularly shaped tumor with extra-thyroidal infiltration” is a cause for alarm for malignancy. There are two types of thyroid nodules, benign and malignant, with benign nodules accounting for the majority and malignant nodules for less than 1%. Therefore, there is no need to worry too much about the thyroid nodules detected during the examination, and they can be treated according to the following steps. 1, check the nature of the nodule, determine whether it is benign or malignant, and at the same time, check the thyroid disease associated with the nodule, “uncover” the source of the disease. If the nodule is a benign nodule, regular checkups should be done once every six months to “keep an eye on” the nodule. 3.Surgical removal can be considered in the following cases: pressure symptoms; combined with hyperthyroidism, and medical treatment is ineffective; thyroid swelling behind the sternum; nodules suddenly increase in size within a short period of time; there is a possibility of cancer. 4. If it is malignant, a comprehensive examination should be conducted and communication with the doctor should be made to decide the specific treatment plan.
