Thyroid cancer is not a terminal disease. People usually talk about cancer and think that once cancer is acquired, it is a terminal disease and cannot be treated or cured. However, among all malignant tumors in clinical practice, thyroid cancer can be cured, so thyroid cancer is not a terminal disease. According to clinical statistics, thyroid cancer usually includes papillary carcinoma, follicular carcinoma, medullary carcinoma and undifferentiated carcinoma, of which papillary carcinoma, follicular carcinoma and medullary carcinoma account for the majority. Most of these three types of thyroid cancer can be cured through timely radical surgery and post-operative chemotherapy, so most thyroid cancers are not terminal and can be effectively cured.
