I should do more homework on how to do this site, but hopefully I am on the right path. I am symptom free, so how did they find my acoustic neuroma? In 2011, I had an unrelated severe headache, had an MRI (w/o contrast as I waived it), and it showed a 4mm or so possible menegioma. My blood test ended up revealing a parathyroid adenoma (too much calcium in blood) which was removed that year at MD Anderson by an awesome doctor. I got a hearing test, as advised after MRI, and had no problems. I had not idea I should be monitoring it. Fast forward to August of this year. I had a physical, and my doctor advised me to monitor it, and sent me for an MRI with and w/o contrast, and schwannoma/acoustic neuroma was neurologist diagnosis. What I didn’t expect was the advice of gamma knife. Doc said my tumor was small enough to do it now, but if it grows, the options are fewer. I will see a radiology oncologist next month for further info. Of course it concerns me. I have decent health for a 58-year-old. I don’t take any meds and am trying to stay clear of ever creeping up BP. Is gamma knife the way to go? I have heard of proton therapy, and MD Anderson is close by. I don’t know the major difference, and if I am even a candidate. I know I am lucky this neuroma was discovered before I had balance and hearing problems. Reading all the posts made me count my blessings on how this unfolded and the options I have. I guess I am looking for advice, information, and experiences. I have read a few already. Thanks for your time.
