Thyroid cancer can usually be cured, but it can not be generalized, whether it can be cured mainly depends on the stage and type of thyroid cancer, as well as the patient’s physical quality, the sensitivity to radiotherapy and so on. 1. Staging of thyroid cancer: early thyroid cancer has mild symptoms, and the prognosis is better for those who have not metastasized, and can be cured through early surgery; advanced thyroid cancer has poor prognosis, and can be treated by radiotherapy. 2. Types of thyroid cancer: Thyroid cancer is mainly divided into papillary, follicular, medullary and undifferentiated cancers, among which papillary and follicular cancers have a better prognosis, while undifferentiated and medullary cancers have a worse prognosis. 3. Physical quality of the patient: if the patient’s physical quality is good, the response to drugs will be better in the process of standardized treatment, and the therapeutic effect will also be better. 4. Sensitivity to radiotherapy: after surgery of thyroid cancer, iodine 131 is often used as a follow-up treatment to remove the remaining tumor cells. Patients who are sensitive to iodine 131 radiotherapy have better curative effect and better prognosis. Patients with neck discomfort need to seek timely medical treatment, early detection and early treatment, and need to be actively treated under the guidance of doctors to avoid delaying the treatment time.
