Master Sgt. Geoffrey VanDyck, 707th Force Support Squadron first sergeant, views an image of the tumor found on his auditory nerve. In May 2005, VanDyck was diagnosed with acoustic neuroma, a noncancerous, normally slow growing tumor that develops on the main vestibular nerve that leads from the inner ear to the brain.
