D44.2: Neoplasm of uncertain or unknown behaviour: Parathyroid gland

When there is abnormal growth of tissue, then this is also referred to as a tumor. The tissue in the body is made up of cells. A tumor disorder involves the cells multiplying more than normal. This results in abnormal or excess tissue forming. A tumor can be benign or malignant.

The parathyroid glands are 4 small glands at the edge of the thyroid gland. A messenger substance is formed in the parathyroid glands. This messenger substance affects the calcium and phosphate content in the body. Calcium from the bone is dissolved by the messenger substance and released into the blood. It thus also affects bone firmness.
