The need for treatment of thyroid nodules should be considered in many ways, and if they are malignant, they should be treated promptly. If a thyroid nodule is benign and there are no functional or cosmetic changes, it can be observed and does not require much treatment, much less surgery. If, after long-term follow-up, the thyroid gland becomes hyperfunctional or is found to be cancerous, or if the benign nodule grows in size and causes severe local pressure symptoms, such as difficulty breathing or swallowing, then surgery is required. If the nodule is malignant, without treatment, the tumor will most likely gradually deteriorate and even develop more extensive metastases, affecting the quality of life. Therefore, it is important to treat malignant thyroid nodules with surgery as soon as possible. When a thyroid nodule appears, attention should be paid to regular follow-up. With effective control, it will basically not affect the quality of life.
