The recurrence rate of papillary thyroid cancer is usually no more than 10%. However, the recurrence rate of papillary thyroid cancer is related to the early and late detection of patients. 1. Timely discovery: papillary thyroid cancer is relatively low in malignant degree and grows very slowly, it is often found during thyroid ultrasonography, and if reasonable surgical treatment is given at this time, the recurrence rate is relatively low, and the survival rate of 5 years can reach more than 90%. 2. Late discovery: when papillary thyroid cancer is found late and lymph node metastasis or even distant metastasis occurs, the survival rate is lower, and the patients can show oppressive symptoms such as difficulty in swallowing and hoarseness, and the recurrence situation needs to be decided according to the treatment of the patients, and radioactive iodine 131 treatment can be carried out to prolong the survival period. For the treatment of papillary thyroid cancer, it is recommended to consult the thyroid surgery department of regular hospitals to avoid delay.
