Thyroid Nodule

Thursday, October 03, 2013

A thyroid nodule is a growth in the thyroid gland, which is located at the base of the neck. Dr. Edward Hill takes a closer look at thyroid nodules in todays 60 Second Housecall.

Dr. Hill:

A thyroid nodule is a small lump in the thyroid. It may be solid or filled with fluid. Some nodules make too much thyroid hormone and cause symptoms such as shakiness, rapid heart rate, anxiety and weight loss.

Doctors do not know what causes thyroid nodules. Most thyroid nodules do not cause symptoms, so people usually dont know they have one. Large nodules can sometimes feel like pressure in your neck, and can make you have trouble swallowing or feel like you are choking.

If you have a nodule that is not causing symptoms and a biopsy does not show any signs of cancer, your doctor may want you to have follow-up ultrasounds to make sure the nodule isnt growing. You may need surgery if you have a large nodule that is causing symptoms.

Nodules that make too much thyroid hormone are usually treated with radioactive iodine. This is a pill that destroys the nodules without damaging any surrounding tissue.
