What Is It?
Parathyroid cancer is a very rare cancer that develops in the parathyroid glands. A pair of these pea-sized glands sits next to the thyroid on either side of the front of the neck.
The four parathyroid glands produce parathyroid hormone (PTH). This chemical
raises calcium levels in the blood by forcing the bones to release calcium
stimulates the intestines to absorb more calcium from food
signals the kidneys to withhold calcium from the urine.
Healthy parathyroid glands adjust their production of PTH to keep blood calcium levels within a normal range.
