Like others, when I found out that I had a Acoustic Neuroma that had to be removed, and soon, I educated myself and posed lots of very direct questions to my nuerosurgeon, who honestly and patiently answered all of them and claimed to be impressed by my knowledge. Thanks to this site and a few others, I was able to ask the 'right' questions and make an informed decision on my AN crisis. Like Gennysmom, I made my choice (retrosigmoid surgery and fractionalized radiation) and as all went well, I am very glad that I made the decisions I made, with some knowledge beforehand, that helped me stay calm, focused and in sync with my surgeon.
It's obvious that you must take 'control' of your medical decisions and to do that, you must be knowledgable about procedures and likely outcomes as well as risks and benefits, etc. This site (aside from the messageboards) is a wonderful source of knowledge for any AN 'newbie', if they wish to make use of it.
