Because of the characteristics of malignant tumors, lymph node metastasis or hematogenous metastasis can easily occur, especially in papillary or follicular carcinoma, which can easily appear as localized masses in the lymph nodes of the neck. Early diagnosis should be promptly treated by surgery to remove the gland and lymph node expansion, and if distant organ metastasis occurs, systemic intravenous chemotherapy and radiation therapy are also required. The occurrence of malignant tumors in the thyroid gland has a certain family genetic tendency and is related to the surrounding work environment and external factors. Regular color ultrasound examination of the thyroid gland and nuclear scan if necessary can detect the lesions at an early stage, and early surgical treatment can significantly improve survival after surgery.
