Thyroid nodules are common and can be detected by palpation as a prevalence of 3-7% of our population, up to 20-70% by ultrasound, and over 40 years old is the high prevalence group. Women are about 6 times more common than men. Although the incidence is so high, more than 70% are benign and there is no need to be nervous about finding this disease. Generally, benign thyroid nodules that are too large with symptoms of pressure or ultrasound suggesting suspicion of malignancy should be treated with surgery as soon as possible. Many benign nodules can be closely monitored and do not require special treatment and have no conscious symptoms. In addition, because the condition of patients varies widely, it is advisable to consult a medical professional once a thyroid nodule is detected.
