<unk>  is a rare cancer resulting in parathyroid adenoma to<unk>  progression. It forms in tissues of one or more of the parathyroid glands (four pea-sized glands in the neck that make parathyroid hormone (PTH). PTH helps the body maintain normal levels of serum calcium by promoting calcium reabsorption from bone. It is antagonized by the hormone calcitonin, which prompts calcium storage.). It is rare, and much less common than parathyroid adenoma. It can be difficult to excise.
