Question: what is the difference between a thyroid and a goiter?
Answer: Enlarged thyroid Widespread enlargement of your thyroid can expand the gland well beyond its normal size and cause a noticeable bulge in your neck. A goiter (GOI-tur) is an abnormal enlargement of your thyroid gland. Your thyroid is a butterfly-shaped gland located at the base of your neck just below your Adam's apple.
