The most important treatment for thyroid tumor is surgical resection. Differentiated and early undifferentiated thyroid cancers are mainly treated by surgical resection, and it is difficult to determine the effect of other treatments such as chemotherapy, so chemotherapy is not recommended for papillary thyroid cancer. Radiotherapy for differentiated thyroid cancer is basically not adopted, except for very advanced palliative radiotherapy. Undifferentiated carcinoma can be treated with chemotherapy, but the prognosis is generally poor. Radioactive nuclear medicine treatment, such as iodine 131, has its own indications and is not suitable for early thyroid cancer. Only local metastasis can be removed completely by neck dissection in cases of primary tumor and lymph node metastasis in the neck, it is also not recommended to apply nuclear medicine prematurely, because after all, there exists radioactive nuclear contamination and the whole body receives radioactive material radiation. Because radiation contamination is a hidden danger, this means does not exclude the possibility of causing the second primary cancer. For patients with multiple metastases throughout the body, such as bone and lung metastases, this treatment is recommended for these patient populations. Patients with cervical lymph node metastasis need to be adopted under the guidance of a doctor. Undifferentiated cancer, usually without iodine intake, iodine 131 treatment is ineffective. Taking thyroid hormone, through exogenous hormone to reduce the blood TSH level, so as to inhibit the growth of the tumor of thyroid origin, to achieve the therapeutic purpose, is the conventional treatment means after surgery, should not be applied for a long time before the surgery (here from the perspective of malignant tumor of the thyroid gland, except for the case of hypothyroidism and other conditions) Therefore, found that the thyroid tumor, can not be excluded from the malignant, it is recommended to operate as early as possible, on the one hand, can be diagnosed at an early stage to On the one hand, early diagnosis can be made to avoid delay in treatment. On the other hand, it can avoid wrong treatment and loss of chance of cure. A large number of patients can be completely cured by early standardized surgery. It is one of the malignant tumors with the highest cure rate.
