An acoustic neuroma can result when Schwann cells overproduce, which may happen due to environmental factors like radiation or continual exposure to loud noises. Though noncancerous and typically slow growing, it can affect both hearing and balance, and may cause hearing loss, tinnitus and dizziness.
