parathyroid hormone tumor symptoms
There may be no signs or symptoms of a parathyroid tumor until there is too much calcium in the blood. Signs and symptoms include weakness and feeling tired. Larger parathyroid tumors may cause a lump in the neck near the thyroid. The parathyroid glands are four tiny glands in the neck near the thyroid gland.The parathyroid glands make parathyroid hormone (PTH), which helps the body use calcium and keeps the amount of calcium in the blood at normal levels. Tumors in the parathyroid are usually benign (not cancer).These are called adenomas.he parathyroid glands are four tiny glands in the neck near the thyroid gland.
