Welcome to (y)our forum, Cathy. If you have any questions, ask away. We're hear to help.
FWIW, I advise that you explore all the treatment options that are open to you. I had my own deep biases (against radiation) when I was initially diagnosed. But the more I looked at the treatment I was most opposed to, the more I became convinced it was the best type of treatment for me personally. Leave no stone unturned and keep an open mind to surgery, CyberKnife (CK), GammaKnife (GK) and FSR radiotherapy. Get multiple opinions from doctors who practice the different types of treatments. After exploring all your options, you will know in your gut which is right for you.
Here are some of the leading doctors (specialists in treating ANs) who will review your MRIs and other tests and give you their recommendations for treatment (you don't need to be their patient):
Dr. Brackmann of House Ear Clinic (Los Angeles, California) will review your MRI and give you his consultation for free over the phone. He developed many of the modern techniques in brain surgery.
Dr. Steven Chang (esteemed neurosurgeon and CK practitioner at Stanford University Medical Center in California; my doctor) will also review your MRI and give you his consultation for free. His email is: sdchang@standford.edu. Dr. Chang has probably treated more ANs with CyberKnife than anyone else in the world. Doctors travel from all over the world to Stanford for their CyberKnife training. CyberKnife was invented by Stanford's Dr. Adler and CK has been in use at Stanford for at least five years longer than anywhere else in the U.S.
You can also get a free consultation by contacting the University of Pittsburgh Medical Center, which has practiced GK longer than any other facility (for over 40 years) in the U.S.
Good luck!
Best wishes,
TW
