Hope it's not too late for my 2 cents worth! I had Gamma Knife and although I will strongly oppose the term "elderly", I will concede that I am a "mature woman" and I am also willing to concede that my neurosurgeon's probably weren't too keen on surgery for me, so strongly suggested I was an ideal candidate for GK. Now, my doctor said that the preferred treatment for AN's depended on what part of the country you lived in, the doctor's choices and what the hospital's had to offer (I would guess...). I am happy with the choice that they helped me make because I was pretty terrified of having to go through brain surgery.
I believe the age thing has to do with the fact that all this new radiosurgery is relatively new, and long term effects....30-40 years...are unknown. So, they figure, I, age 60 at the time of my treatment, probably won't live 30 or 40 more years, so that's not important. So, a younger person, they think, ought to risk the surgery. I am not in the least bit concerned that my treatment will end up causing me to have cancer. It's a very minute possibility. My risk of getting killed in a car accident on the way to GK was much, much, much greater.
I would make the same decision again, if I had to. But, I'm 62 now, so don't know if my experience is what you want to hear. I just know that many, many people have the surgery and are happy with the results, and go on with their lives. And many, many people have radiosurgery and are happy with the results and go on with their lives.
I would not let doctors "scare" you into one treatment over another. There was a story on CBS news the other night about Proton Beam and the patient they were talking about was a young woman losing her eyesight to a mengionoma and she was treated successfully with radiation. Heck, she looked like she was 25. So, what's the difference with that and with what you might do?
I wish you the best of luck with your decision and eventual recovery. This isn't a fun path we've all found ourselves on, but it's one of the detours of life, and whatareyagonnado?? You just deal with it the best that you can and have some faith in our medical system and GET THE BEST DOCTORS THAT YOU CAN GET!!
