I have an acoustic neuroma and was going to go through that big, bad surgery. I prayed about it and got an answer to prayers. Gamma Knife "surgery" was performed on Nov. 23, 2012 at Midland Medical Center, in Midland, Michigan. It is non-invasive, however, it shoots nuclear rays to the tumor. I also have a Meningioma above my left eye. I lost most of the hearing in my right ear, and have constant ringing and chirping in that ear as well. A hearing aid doesn't help much because of the damage done by gamma rays. I have had 2 MRI with contrast since 2012 and both tumors have not grown, but aren't gone. I still have balance issues, but I blame that on having both knees total replacement and ankle and arch reconstruction in the past 5 year. I also try to live life to the fullest, even with all of the major surgeries I've gone through. I actually don't think about the tumors very often because so far they are benign. Good luck and prayers to anyone going through this issue. But please check out the Gamma Knife procedure.
