The early cure rate of thyroid cancer is very high, and the 10-year survival rate can be more than 90%. There are different types of thyroid cancer with different pathologies, treatment and prognosis, with papillary carcinoma being the most common, and about 75% of patients’ thyroid cancers are papillary carcinoma. Most patients can be cured with early detection and timely treatment. Patients with papillary thyroid cancer should be tested for thyroid function, thyroid ultrasonography, and thyroid hormone suppression after surgery. Most papillary carcinomas recur within 5 years after surgery, and a few of them recur in 10-15 years, so if there is no recurrence in the follow-up more than 10 years after surgery, it can be considered as clinical cure. On the other hand, non-differentiated tumors such as medullary carcinoma, which are highly malignant and difficult to cure, must be regularly reviewed and radioactive iodine excision must be performed when necessary. If patients develop uncomfortable symptoms, they should go to the hospital for consultation and treatment in time.
