Thyroid malignancy usually refers to malignant tumors of the thyroid gland. Thyroid malignant tumor belongs to thyroid cancer, which is a common type of malignant tumor. If thyroid malignant tumors are detected, diagnosed and treated at an early stage, most patients can be cured by radical surgical resection. However, for patients with late detection and more serious progression, the possibility of complete cure is relatively small, and only through chemotherapy, radiotherapy, targeted drug therapy, etc., to achieve the effect of controlling the growth of the tumor, avoiding or delaying the spread of the tumor, in order to extend the life of the patient to the greatest extent possible. Therefore, once a malignant tumor of the thyroid gland is detected, it is necessary to consult a doctor as soon as possible, and strictly follow the doctor’s instructions for examination and treatment, so as to avoid delaying and triggering greater health losses.
