A thyroid tumor is an occupying lesion that grows in the thyroid gland and can be classified as a benign or malignant tumor. The survival time of patients with thyroid tumor varies according to the tumor development, patient’s physical condition and treatment, so it is difficult to make an exact assessment of the survival time of patients, but carrying out active and effective treatment usually prolongs the life of patients to some extent: i. Benign tumor: If the patient is benign thyroid tumor, after effective treatment, it usually has less impact on the life time. Most of the population has a survival rate of more than 10 years. Malignant tumors: 1. papillary thyroid cancer: after systematic treatment, papillary thyroid cancer usually has a better prognosis and less impact on the length of life, and most patients have a survival rate of more than 10 years; 2. follicular thyroid cancer: although follicular thyroid cancer may have some impact on the length of life, after systematic treatment, some patients have a life time of 10-20 years, but some patients may have long-term carriage. However, some patients may survive with tumor for a long time; 3. Medullary thyroid carcinoma: the survival period of patients with medullary thyroid carcinoma may be slightly shorter, some patients may have a survival rate of 5-10 years, but some patients may also have a survival rate of more than 10 years; 4. Undifferentiated thyroid carcinoma: undifferentiated thyroid carcinoma is a more difficult type of cancer to cure, which has a greater impact on human life and a poorer prognosis. The survival time is usually about 1 year, and some patients may have a survival rate of 5 years or more; 5. Thyroid lymphoma: It is a kind of lymphoma originating from the thyroid gland, which is relatively rare. Other: If patients have metastasis to other organs of the tumor, such as lung metastasis, lymphatic metastasis, brain metastasis, etc., the survival rate of patients may also be reduced to some extent. Besides, the age and treatment method of thyroid tumor patients may also have some influence on the survival rate. For example, young people and people with better health will have a slightly longer survival time after having thyroid tumor than those who are old or have other underlying diseases. Patients who are actively treated with anti-tumor therapy such as surgery, radiotherapy, chemotherapy and targeted therapy may have a relatively longer survival time.
