A goiter is an abnormal swelling of the thyroid gland that causes a lump to form in the throat. The thyroid gland is a small butterfly-shaped gland in the neck that is located just in front of the windpipe. It produces thyroid hormones, which help to regulate the body’s metabolism. The thyroid gland is not usually noticeable. However, if it swells it produces a lump in the throat that is known as a goitre
