The mortality rate of thyroid nodules is very low, even thyroid cancer is only about 4 per million, because thyroid nodules is the general term for swelling in the thyroid gland, which includes benign thyroid nodules and malignant tumors of the thyroid gland. Benign thyroid nodules include thyroid adenomas, nodular goiter, Hashimoto’s disease, hyperthyroidism, etc. Most of these diseases can be controlled by medication, and at the same time adjusting the dietary structure and lifestyle habits can alleviate the progression of the disease, while a small number of them require surgical intervention, which basically has a lesser impact on the length of life. The malignant tumors of thyroid gland include papillary thyroid cancer, follicular thyroid cancer, medullary carcinoma, undifferentiated carcinoma and so on, of which the first two types account for the majority, and the survival rate is also high through active surgical treatments, regular medication and regular follow-up after surgery.
