Just to throw in my two cents (Euro) worth of it: funny thing about statistics and figures and so on, we're not statistics. None of us are. All of us are our own case of AN, we're all different, and furthermore there are no guarantees in this, whichever treatment option one prefers or feels more comfortable with. One can read all the papers one wants, digest all the opinions one hears, absorb and assimilate unbiased opinions, reject biased ones, but in the end of it all, you are the one making the decision. Ok, you'll make an 'informed' decision, the the bottom line is, there are no guarantees for you. I'm just trying to say that in the end (as Raydean and others have already said) your decision will be based on what gives you the most reassuring feeling, what feels right to you, having had all the information.
in my case i was a candidate for both surgery and radiosurgery. I read and read and discussed and thought, until my eyes popped out and my brain couldn't take any more. In the end, the information I got for different options was so close in terms of outcome, it really didn't figure that much in it. Ok, I preferred CK finally, as the prospect of no recovery problems really appealed to me. Right. Felt good, felt right, that was it. I traveled half way around the world to get CK. Wonderful experience and a holiday to boot! Brilliant. That's until i came back here and then it hit. had the most awful 8 months of not functioning properly mentally, and a fatigue so BIG I felt I would never be able to work/live the same way again. I still think I made the right choice for me, I really didn't feel comfortable with the idea of somebody rooting around my brain with metal tools, regardless of what surgical demi-dog they would have been. But the 'no recovery problems' was a total misnoma. I didn't fit the statistics, obviously. Turns out I was my own case, with my own particular set of circumstances. My ooutcome was just as individualistic as i am, we all are.
As for the future, well, it'll turn out the way it wants. Who knows. Surgery? Leave a cell behind and it starts growing again? Radiosurgery and the darn goopy mess starts acting up and decide to make a comeback? Well, that'll be down the road, I'll deal with it then. Either I'll find the surgical demi-god I missed the llast time, or they'll have some other form of treatment by then. Regardless, I'll do something.
That's of course if the AN comes back. No guarantees, either way.
PS: oh, and by the way, I am now doing great, nearly three years post CK. BAck to doing all I did before and more than i have in a long time. Still have some effects, but I learned to live with them and avoid them as much as possible. I think my brain is working again, sort of...
