Stereotactic Proton Radiosurgery

The Proton Beam Unit at Mass General was founded in 1962 and has the largest experience with stereotactic radiosurgery of any center in the United States. Learn more about these advanced procedures.

Our Approach

In some patients, proton beam therapy and conventional radiation therapy may be appropriate for treatment of pituitary lesions. Laser-guided MR imaged stereotactic intrasellar tumor localization can be used for selected patients with untreated pituitary tumors, incomplete surgical resection, or tumor recurrence.

Conditions & Diseases

  • Pituitary Tumors

    Although rare, most pituitary tumors are not cancerous (benign), comprising only 7 percent of brain tumors. However, most pituitary tumors will press against the optic nerves, causing vision problems.
