Clinically, if a thyroid nodule is confirmed to be a benign tumor, generally speaking, if thyroid function is normal and the nodule is not large, urgent treatment is not necessary, and regular follow-up is sufficient. If the thyroid nodule significantly enlarges, causing compression of the trachea or nerves, surgery should be considered. Furthermore, for ectopic growth of thyroid tissue behind the sternum, surgical removal is also considered necessary. Another scenario that requires special mention is if a thyroid nodule grows rapidly in a short period and ultrasound suggests calcification or bleeding within the cyst, thyroid cancer should be suspected. In this case, it's advisable to have the nodule surgically removed.
