Early stage thyroid cancer may survive for a long time if it can be surgically removed in time, or it may survive for several months to several decades. The specific survival time is related to the pathologic typing of the cancer cells and whether it can be treated in time. Pathologic type: Early thyroid cancer can be divided into papillary, follicular, medullary and undifferentiated carcinomas. Among them, papillary carcinoma and follicular carcinoma are relatively low in malignancy and generally have good prognosis after timely surgery, some patients can be cured and will not affect life expectancy, and a few patients may recur if they have recurrence and may last for 10~20 years. In case of medullary carcinoma or undifferentiated carcinoma, the degree of malignancy is relatively high and the progression is relatively fast, even if it is treated by early surgery, the risk of recurrence or metastasis is higher and the survival time will be shortened. The longest time can be up to ten years of productivity, while the shortest time may be only a few months. Timely treatment: For early thyroid cancer, timely detection and standardized treatment are very crucial and important factors affecting the prognosis. Some patients may not be able to undergo timely surgical treatment due to various objective factors, which may delay the treatment of the disease and shorten the survival time of the patients. Early thyroid cancer is recommended to be treated as early as possible in order to prolong the survival time.
