Chris ~
I concur with the folks that advise you to obtain second/third opinions - with the caveat that if you find a doctor that, as Jan did, you feel confident with, trust his judgment and skill, go with that doctor and his recommendations. Like Jan, I was fortunate to find that 'special' doctor - a neurosurgeon - on my second consultation, the first being a total waste of my time (he was intimidated by the size of my AN and fudged on how many AN surgeries he had performed. All red flags, for me). My trust in that 'special' doctor was amply rewarded with a very good outcome to the surgery and later (planned) radiation. Do try to avoid information overload and remember that in many cases, you'll receive conflicting advice. However, ultimately, the decision on treatment remains in your hands. Of course, your friends here at the ANA discussion forums stand ready to support whatever treatment choice you make.
