I had surgery to remove my acoustic neuroma about 7 years ago. I was diagnosed with a regrowth (same exact size as when I initially went in) at my first follow up MRI two years later.
I did quite a bit of research (a little too late) and cannot believe that none of my doctors advise me not to have dental x-rays, as it is believed that this could be the cause of the AN. And, those high-contrast dyes that are used in the MRI's are toxic heavy metals. Please, do some research. I don't have much faith in doctors anymore.
