Parathyroid Adenoma


A parathyroid adenoma

is a benign (not cancerous) tumor on one or more of your parathyroid glands. The parathyroid glands are 4 small glands located near the thyroid gland in your neck. The parathyroid gland produces parathyroid hormone (PTH). PTH keeps the level of calcium balanced in your blood. A parathyroid adenoma can cause extra PTH to be produced. This condition is called hyperparathyroidism. Hyperparathyroidism can cause blood calcium levels to increase, and lead to health problems such as osteoporosis (weak, brittle bones). The cause of parathyroid adenomas is usually not known.
