Your thyroid is a small, butterfly-shaped gland in the front of your neck. Its main job is to produce thyroid hormones, which help regulate your body's metabolism and control your heart rate, body temperature, growth and development. A thyroid nodule is a small bump or growth that develops on this gland. Thyroid nodules can cause a range of symptoms—or none at all.
