Thyroid nodules can be treated with medications such as levothyroxine sodium and iodine 131. Thyroid nodules are categorized into benign and malignant nodules. A fine needle aspiration cytologic biopsy is a more accurate test to determine the benign or malignant nature of the nodule. A nuclear thyroid scan is more accurate in assessing whether the nodule has a secretory function. Benign nodules usually do not require specific therapeutic intervention, and follow-up is sufficient. It is recommended to go to the hospital every 3-6 months for review. Larger sizes that cause compression symptoms and retrosternal swelling of the thyroid gland can be treated surgically. For fine-needle puncture suggests that the nodule may be malignant, need to carry out surgical treatment, some patients need to take thyroid hormone treatment for life. Thyroid nodule patients also need to draw blood to check whether the thyroid nodule has the function of secretion, for the secretion of thyroid hormone nodule, need to carry on iodine 131, take levothyroxine sodium and other drugs and surgical treatment. If thyroid nodules are present, it is recommended to seek timely medical treatment so as not to delay treatment and affect the prognosis.
