Gamma Knife® Surgery Treatment of Pituitary Adenoma
Questions? Call 513-686-5972
Pituitary tumors are abnormal growths that develop in the pituitary gland. Some pituitary tumors result in too many of the hormones that regulate important functions of the body. Some pituitary tumors can cause the pituitary gland to produce lower levels of hormones.
Most pituitary tumors are noncancerous (benign) growths (adenoma). Adenoma remain in the pituitary gland or surrounding tissues and don't spread to other parts of the body.
Doctors generally use surgery, radiation therapy and medications, either alone or in combination, to treat a pituitary tumor and return hormone production to normal levels. Radiation therapy can be beneficial if a tumor persists or returns after surgery and causes signs and symptoms that medications don't relieve.
Delivered as a single high dose, the Gamma Knife® focuses radiation beams on the tumor without an incision. It delivers radiation beams the size and shape of the tumor into the tumor with the aid of special brain-imaging techniques. Minimal radiation comes in contact with healthy tissue surrounding the tumor, decreasing the risk of damage to normal tissue.
With Gamma Knife® surgery, a patient can often:
- Be treated in one session
- Experience less damage to healthy cells and tissue
- Enjoy faster recovery times
- Gain better quality of life
