A pituitary tumor is an abnormal growth of cells in the pituitary gland. The pituitary gland is a pea-sized gland located at the base of the brain behind your nose. It controls many other glands in your body and the amount of hormones that these glands make.
The word tumor does not always mean cancer. Most pituitary tumors are benign (non-cancerous).
