The five-year survival rate of medullary carcinoma is about 46-98%, and the specific survival period is mainly related to the stage of medullary carcinoma, and most of the patients can survive for a long time with early treatment by radical surgery. Medullary carcinoma is a special type of thyroid cancer, which is relatively rare among thyroid cancers, and can usually invade the lymph nodes in the neck or develop blood metastasis. When medullary carcinoma is detected in early stage and the cancer cells have not invaded lymph nodes or metastasized, it is usually treated with surgery and complete resection, combined with radiotherapy when necessary, and most patients will not have any impact on their life expectancy. However, for advanced medullary carcinoma, according to foreign statistics, the five-year survival rate of stage 1 can reach 98%, the five-year survival rate of stage 2 is 94%, the five-year survival rate of stage 3 is 94%, and the five-year survival rate of stage 4 is 46%. In general, the earlier the disease is detected, diagnosed and treated, the less impact it has on life expectancy. Patients are advised to be admitted to the hospital in time after diagnosis to avoid delaying the disease and affecting survival.
