The survival rate of papillary thyroid cancer with lymph node metastasis is longer, and the survival rate of ovarian thyroid cancer with lymph node metastasis can reach more than 80% in 5 years. The most important feature of papillary thyroid cancer is that lymph node metastasis can easily occur even in the early stage. As long as radical thyroid cancer surgery is performed in time and lymph nodes in the central region or around the neck are completely cleared, the survival time is significantly improved compared with other malignant tumors. Regular post-operative review, combined with pathology, and appropriate iodine-131 radiotherapy can help improve the survival time and cure rate of papillary thyroid cancer after surgery.
