Bruce, I also appreciate your thoughtful, intelligent posts and am so glad you are helping people to see both sides of the story.  I, too, am rather aghast at how doctors just slide a person towards surgery without revealing what's behind door number 2.  My choice would be non-invasive first, brain surgery second (unless, of course, this is the only option due to other circumstances such as size and location).
Sefra22 -  Gamma Knife usually does what it's supposed to do. It kills the bugger.  It's just that it takes a little longer to do that than scooping it out of your head.  The only downside that I can think of is that a person then has to wait and see what happens in 6 months, and then 6 months after that, and then maybe a year after that.  I am going on 9 months since my GK last April and I have another MRI coming up.  Hopefully I will get news that necrosis has begun.  But if I don't then I will have to wait until the next time.  I still have my symptoms that I had before I went in.  I still have tinnitus (surgical patients usually retain that as well), I am still "severely" deaf in my left ear and I still have numbness on the left side of my face (which includes the inside of the left side of my mouth). My doctor hoped that the numbness would go away, but I have resigned myself to all of these symptoms for the rest of my life. If something gets better, then wonderful. If it doesn't, then I figured it probably wouldn't anyway.  I don't have, for some reason which I am grateful for, dizziness or balance problems to a degree that is debilitating or bothersome.  I did notice this when I walked on the soft sand at the beach, however!  Very weird.

So far I am not sorry I had Gamma Knife.  Good luck to you in whatever treatment you choose and recovery. ÂÂ
