Acoustic Neuroma / Vestibular Schwanoma Info

Acoustic neuromas, also known as vestibular schwannomas, constitute approximately six percent (6%) of all brain tumors.  These tumors occur in all races of people and have a very slight predilection for women over men.  In the United States, approximately ten (10) people per million, per year are diagnosed with an acoustic neuroma.  This translates to roughly three thousand (3,000) newly diagnosed acoustic neuromas per year in the United States based upon a population of around three hundred million.
