Thyroid

The thyroid gland is in your neck and helps control how your body uses energy and makes proteins. It also affects how sensitive your body is to other hormones. A thyroid ultrasound is a test that uses sound waves to look for any abnormal lumps or growths in your thyroid. It can help your doctor figure out if the growth is a cyst, enlargement, nodule, or tumor. The ultrasound can also be used to monitor the size of any known growths over time. The information from the ultrasound will help your doctor decide if any other tests are necessary.
