Thyroid cancer is a malignant tumor of the thyroid gland, which is a kind of cancer, but most of the thyroid cancers have low malignancy and relatively high cure rate. Thyroid cancer can be categorized into papillary carcinoma, follicular carcinoma, medullary carcinoma, and undifferentiated carcinoma according to its pathology, and more than 90% of thyroid cancers are papillary carcinoma and follicular carcinoma, which are characterized by low malignancy, high cure rate and survival rate, and good recurrence after surgery, therefore, in people’s impression, the survival period of thyroid cancer is longer, and they may ignore that it is a kind of cancer. It is worth noting that, although the cure rate of thyroid cancer is high, if the diagnosis of thyroid cancer is not timely, the condition is prolonged and distant metastasis occurs, the difficulty of surgery will increase and the cure rate will decrease. Therefore, after diagnosis of thyroid cancer, timely consultation should be made and surgery should be performed as early as possible.
