Thyroid cancer is a relatively common malignant tumor of the head and neck. Among thyroid cancers, papillary thyroid cancer is the most common and the best treated one, so it is not very scary. However, it also depends on the stage of papillary thyroid cancer. If it is the majority of early stage, it can be treated by surgery with good effect. Even if there is metastasis in the surrounding lymph nodes, most commonly in the neck, and the stage is not too early, it is possible to consider radical thyroid cancer treatment, including neck lymph node dissection. The general survival rate of 5-10 years can reach more than 90%. After surgery, if the number of lymph node metastases in the neck is high, it is necessary to combine with nuclear iodine-131 treatment and long-term oral thyroxine tablets after surgery.
