However, the growth rate of thyroid nodules cannot be used to determine whether the nodules are cancerous, but is only one of the reference signs to determine whether the nodules may be malignant. In addition to the growth rate, it is also necessary to combine the growth pattern, for example, if the nodule was growing horizontally in the early stage and now it is growing longitudinally, and the ultrasound describes an aspect ratio >1, the degree of malignancy is higher at this time. If the nodes show gravelly calcification, hardness, unclear borders, abundant blood flow signals, adhesions to surrounding soft tissues, and lymph node metastases, especially punctate gravelly calcification in the lymph nodes, the nodes are more likely to be malignant. In addition, the patient’s family history should be taken into account, and the presence of a history of ionizing radiation should be clarified. If the nodule is benign, no medication is needed, and acupuncture, local massage, and regular observation are sufficient. If the nodule is malignant, surgical treatment is required and a puncture biopsy is performed prior to surgery. If the puncture result is benign, observation will continue, and if the result is malignant, the patient should be operated as soon as possible.
