Causes
By Mayo Clinic staff
The cause of uncontrolled cell growth in the pituitary gland, creating a tumor, remains unknown. The pituitary gland is a small, bean-shaped gland situated at the base of your brain, somewhat behind your nose and between your ears. Despite its small size, the gland influences nearly every part of your body. The hormones it produces help regulate important functions, such as growth, blood pressure and reproduction.
A small percentage of pituitary tumor cases run in families, but most have no apparent hereditary factor. Still, scientists suspect that genetic alterations play an important role in how pituitary tumors develop.
