Sorry to hear about your AN. There are several of us on here who were treated at Georgetown. If you do a search for Georgetown, hits will come up. My only advice would be to consult with mulitple physicians and read, read, read before deciding. I was treated with CK a year following diagnosis when the repeat MRI showed that the tumor had grown faster than the norm. Just remember that the specialist you see tends to recommend treatment in their field. When I went to Georgetown for consults, I was required to see a neurosurgeon even though I had already made up my mind for CK. And as expected, he recommended surgery. I then saw the radiation oncologist. I'm from SC so several months later I returned for treatment. I'm very pleased so far. Very few side effects which were mild. My AN hearing decreased slightly but still remained within the low end of normal. I do think it's decreased some since my last exam in 1/09. Will probably have follow-up exams in January.
