Definition
By Mayo Clinic staffPituitary tumors are abnormal growths that develop in your pituitary gland. Sometimes pituitary tumors can cause excessive production of hormones that regulate important functions of your body. Other times, pituitary tumors can restrict your pituitary gland, causing it to produce lower levels of hormones.
Most pituitary tumors are noncancerous, nonspreading growths (adenomas). Adenomas remain confined to your pituitary gland or surrounding tissues and don't spread to other parts of your body.
Treatment for pituitary tumors involves various options to either remove the tumor or control its growth. You may also need medications to correct hormone production that is too high or too low.
