Thyroid nodules are a common clinical thyroid disorder and can be seen in endocrinology and thyroid and breast surgery. Thyroid nodules are a common clinical thyroid disease. The nature of nodules is clarified by thyroid ultrasound, CT examination and fine needle aspiration cytology. If the thyroid nodules are small and considered benign, they can be followed up in the endocrinology department for observation. If the nodules are found to be growing faster, they should go to the thyroid surgery department in time, and if the thyroid nodules are clearly malignant, they should be treated with surgery as early as possible. Patients with thyroid nodules should follow the doctor’s instructions for examination and treatment, and please consult the doctor in time when discomfort occurs.
