The parathyroid glands are four tiny glands, located in the neck, that control the body's calcium levels. Each gland is about the size of a grain of rice (weighs approximately 30 milligrams and is 3-4 millimeters in diameter).
Parathyroid Adenoma. Your parathyroid glands, four very small glands located near or at the back of the thyroid gland, produce parathyroid hormone (PTH). This hormone helps control the amount of calcium and phosphorus in your blood. A parathyroid adenoma is a benign tumor on one of these glands. This causes your calcium and phosphorus balance to be disrupted, as the affected gland releases more PTH than it should. This condition is called hyperparathyroidism.
