Papillary thyroid cancer is the most predominant type of thyroid cancer in adults and also the entirety of thyroid cancer in children. This type is better differentiated, less malignant, and has a better prognosis although it often has a central lesion, involves about one-third of the thyroid gland bilaterally, and has early metastasis to the cervical lymph nodes. In recent years, many experts have called for the removal of papillary thyroid cancer from the list of malignant tumors and its classification as a chronic disease, mainly because papillary thyroid cancer has a good prognosis and can be cured by early detection and surgery. Epidemiological surveys have found that papillary thyroid cancer has the highest 10-year survival rate of 98% among thyroid cancers, but the prognosis is also highly related to the presence or absence of lymph node metastasis. Moreover, patients with this type of tumor are often asymptomatic and the tumor grows very slowly, some patients can be diagnosed as long as decades from the onset of the disease. Clinically, there are few manifestations associated with malignant tumors, such as wasting, pain, local pressure, etc. Therefore, about half of the patients are often easily mistaken for benign lesions. Although papillary thyroid cancer is positioned as malignant tumor, its characteristics are not the same as those of malignant tumors in other organs of human body. Cancer progresses very slowly or even does not progress, and most of them have good prognosis, and early treatment can achieve curative effect. Therefore, there is no need to be too nervous and anxious about papillary thyroid cancer. However, it is also necessary to seek timely and reasonable treatment according to the situation.
