I have to chime in here. I had both surgery and radiation (in a planned sequence) so I guess I would recommend both. Well, not really, because my AN's size, location and growth rate were specific to me and my doctor recommended the procedures he considered best for my situation. Fortunately, he was correct and it all worked out quite well.
Besides, although most AN surgery or radiation patients do just fine, some AN patients have less-than-satisfactory outcomes with surgery and some have equally unsatisfactory outcomes with radiation so I doubt they would be eager to recommend one or the other based on their experience. Obviously, it's all relative to the individual. That - and the fact we're not doctors - is why we don't make specific treatment recommendations to 'newbies', just suggestions. As Jan stated, after receiving treatment opinions from trained, licensed medical professionals, we advise AN patients to go with their instincts, also known as their 'gut'. As I think you know, that approach usually works out just fine.
