Papillary thyroid carcinoma is a malignant tumor, but it is inert. Nowadays, some comments think that papillary thyroid cancer is not a malignant tumor, but from the clinical and biological characteristics of papillary thyroid cancer observed so far, it is still a malignant tumor, but it is better differentiated, with a lower degree of malignancy, and early lymph node metastasis can also occur. In advanced stage, bone, brain and lung metastasis can occur, therefore, papillary thyroid cancer should be treated actively and followed up regularly. For patients with papillary thyroid cancer, if the cancer is small, regular follow-up observation is recommended in foreign countries, such as the United States, Japan and South Korea, because they think that this kind of cancer doesn’t need surgery and doesn’t affect the survival period of patients. However, in China, once papillary thyroid cancer is detected, it is still recommended to be actively treated with surgery in order to get a better survival result. The commonly used surgical method is radical thyroid cancer surgery with regional lymph node dissection. If there is no lymph node metastasis, central lymph node dissection is also needed to prevent this from happening. In addition, endocrine treatment can be done after surgery, such as long-term oral levothyroxine sodium tablets, which can also lead to a good survival.
