Our surgeons regularly perform surgery on the endocrine system, including the thyroid, parathyroid and adrenal glands. This system secretes hormones that keep much of the rest of your body running. If these glands make too much or too little of a hormone, it can upset the way the rest of your body functions. It can also lead to an enlarged thyroid, called a goiter. In certain cases, or in cases of thyroid cancer, surgery is needed on the endocrine system. Learn more about the thyroid and associated glands by clicking here.
