Parathyroid adenoma

Definition of Parathyroid adenoma

A parathyroid adenoma is a noncancerous (benign) tumor of the parathyroid glands, which are located in the neck.

Causes, incidence, and risk factors

The parathyroid glands in the neck help control calcium use and removal by the body. They do this by producing parathyroid hormone, or PTH. PTH helps control calcium, phosphorus, and vitamin D levels within the blood and bone.

Symptoms

Many people have no symptoms. The condition is often discovered accidentally when blood tests are done for another medical reason.

Signs and tests

Blood tests are done to check the levels of parathyroid hormone, calcium, phosphorus, chloride, and bicarbonate.

Treatment

Surgery is the most common treatment. However, if you have mild hyperparathyroidism, you may just need regular check ups with your doctor.

Expectations (prognosis)

The outlook is generally good.
