The parathyroid glands are responsible for controlling the calcium in the body. There are four parathyroid glands, two on each lobe of the thyroid gland. They are located at the base of the neck.
Parathyroid cancer is an extremely rare type of cancer. Men and women are equally affected. It usually occurs in people older than 30.
The cause of parathyroid cancer is unknown. People with multiple endocrine neoplasia type I have an increased risk for this disease. People who had head or neck radiation may also be at increased risk. Such radiation exposure, however, is more often connected with thyroid cancer.
Parathyroid cancer is a slow growing cancer. It is also extremely hard to diagnose.
