    • MRI or CT scans to detect tumors in the pituitary gland

    • Vision testing

    Treatment of pituitary cancer depends upon the size and extent of the tumor along with its hormone producing nature. It may include: 

    • Surgery to remove the pituitary gland by any of the following approach:  

      • Endoscopic transnasal transphenoidal approach

      • Transcranial approach (craniotomy)  

    • Radiation therapy by: 

      • Gamma Knife stereotactic radiosurgery

      • External beam radiation

      • Proton beam therapy
