Many patients have inquired about the prognosis of papillary thyroid cancer, so here is a brief introduction. Papillary thyroid cancer is the most common type of thyroid cancer, accounting for more than 85% of all thyroid cancers. The surgical statistics of our department in recent years even show that papillary thyroid cancer accounts for 93% of all malignant thyroid tumors. Papillary carcinoma is also the least malignant of all thyroid cancers. Micro papillary thyroid cancer refers to cancer with tumor less than or equal to 10mm, which has a better prognosis and many patients do not have any symptoms for many years. Therefore, some patients ask whether micro papillary thyroid cancer can be treated without surgery. For microscopic cancer less than 5mm, indeed, some scholars currently believe that no special treatment is needed, and that it can be closely observed, and it is not too late to do surgery if problems arise. However, for papillary thyroid cancer larger than 10mm, surgery is still recommended because good prognosis of papillary thyroid cancer is based on standardized surgery. Standardized initial surgery can solve the thyroid problem once and for all, so that the patient will not be troubled by thyroid cancer for life, why not?
