Whether a thyroid nodule requires surgery depends on the size and nature of the nodule. Generally, small benign thyroid nodules usually do not require surgery; for large thyroid nodules that produce pressure symptoms or suspected malignancy, surgery is usually required. 1. Benign nodules, including thyroid adenomas and nodular goiter, are more common in clinical practice, and most of them do not require surgical treatment. 2. When thyroid nodules cause breathing difficulties or difficulty in swallowing, thyroid surgery is usually considered. 3. If the nodules are malignant in nature, thyroidectomy is usually required. It is recommended that patients with thyroid nodules be treated under the guidance of a doctor.
