Thyroid nodules are lumps that form on the thyroid, and they are characterized by solid or fluid-filled lumps, according to Mayo Clinic. Although most thyroid nodules do not cause any outward symptoms and are not considered serious, some can grow so large as to be seen or felt at the base of the neck and potentially press against the windpipe or esophagus, restricting the ability to swallow and breath. In some cases, the nodules develop into cancer.
Treatment depends on the type of nodule that a patient has, and treatment options include physical examinations coupled with regular thyroid function testing, thyroid hormone suppression therapy, radioactive iodine, and anti-thyroid medications, as Mayo Clinic explains. In the most severe cases, surgery to remove the thyroid may be necessary.
The thyroid is a small gland located at the base of the neck that produces and stores hormones that help regulate metabolism, according to MedicineNet. These hormones regulate physical functions such as heart rate, blood pressure and body temperature, and they are also instrumental in the growth and development of children.
