Cancer is a malignant tumor and definitely has a certain mortality rate. It is just that in the medical community, including doctors and people in the field of thyroid, thyroid cancer is considered as a lazy cancer, lazy cancer that will not kill anyone. In fact, it is wrong, so whether thyroid cancer will die or not, it should be divided into at least four major categories. From the professional point of view, thyroid cancer is divided into papillary, follicular, medullary and undifferentiated carcinoma. The survival rate of patients with papillary and follicular carcinoma is very high, which means that if you have to have a cancer in your life, you should have this kind of cancer because the treatment effect is very good. Early stage papillary and follicular cancers can be completely cured, especially microscopic cancers, and the recurrence rate is only 4% or even lower in 20 years. So thyroid cancer depends on the specific details, the specific medical classification.
