Researcher, welcome,,
First, sounds like you are off to a proactive approach to your AN diagnosis,,, good for you! This will help you find the best Dr team for you and eventually you will be comfortable and confident in your very personal decision. It IS ultimately up to you and your family to decide what is best for you.
The ANA site does provide a list of qualified Drs, but keep in mind the ANA does not endorse any Drs and these Drs have paid to be listed by donations or membership. But it is an excellent starting point with that in mind. There are MANY other qualified Drs out there.
If you are close to UF- Gainesville,, Dr. William Friedman practices there and they preform both surgery and radio surgery and also have started using Avastin as a medical treatment for ANs,, you can look on their website. Not sure how close you are to that team. Just an option.
Good luck in your search. There are several Drs who will review your MRI CD and consult over the phone. House clinic in LA, CA is one. This can be an invaluable asset and worth pursuing.
Let us know how it goes. Relax and don't get too overwhelmed researching!! There are plenty of options yet open to you.
