Seeing through it
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.
