It also costs about$140 for a thyroid ultrasound, and a thyroid function test is required before doing so. The thyroid ultrasound examination can clarify whether there are currently any thyroid nodules, thyroid cysts, thyroid cancer or subxiphoiditis, and other diseases. If the ultrasound suggests malignant ultrasound manifestations, such as hypoechoic, calcified foci, non-smooth edges, unclear borders, and lymph node abnormalities, it suggests a 95% likelihood of cancer. At this time, it is necessary to timely resect the diseased tissue and send it to the pathology to clarify the specific pathological type, actively carry out local lymph node clearance, and if necessary, cooperate with radiotherapy, chemotherapy and other treatments. Generally, the malignant rate of thyroid cancer is relatively high, so it should be treated in time.
