Of all cancers in the human body, the one with the highest survival rate is papillary thyroid cancer. Papillary thyroid cancer is the most common type of thyroid cancer, which can account for more than 60% of thyroid cancers. Papillary thyroid cancer is slow-growing, less malignant and has an excellent prognosis, with a 10-year survival rate of over 80% after surgery. The tumor is usually round in shape and 2-3 centimeters in diameter. Although there is no envelope and local lymph node metastasis is often associated with the tumor, the incidence of distant metastasis is extremely rare. Most patients with papillary thyroid cancer are completely cured after surgery. As long as thyroxine tablets are taken regularly after surgery to stabilize the hormone level in the normal range, post-operative thyroid cancer patients can work, study and live like normal people.
