welcome to the "club"..
one thing I did and would recommend is to send your MRI and any auditory testing you have had to the House Clinic in Los Angeles (HEI.org) for a free consultation.
They will look at your info and have a phone conversation with you with "no obligation" to have treatment done there. I did it and it was most helpful to have their opinion. They are some of the top Drs. in the country for ANs, some will tell you they will lean toward surgery, but they also do radiation from what I understand. The Dr I spoke with did agree with me that I could w&w the first year I sent MRI, then the next year I sent the next MRI and he suggested I proceed with surgery as mine had grown and was pressing on the brain stem and radiation was not an option at that point. There are other facilities also who will provide this type of consult. I believe that the more opinions you can get the more educated you will be to options and exactly what is going on.. that is one thing about it,, everyone has an opinion,, but at least you can determine what the consensus is about treatments/or not and also about size, location and what it may be impacting from the different drs..
One thing with w&w,, is IF it grows , it may rule out radiation at some point and you will have to have surgery, if w&w is no longer an option. So it is beneficial to have that "gut" feeling about the different scenarios ,, whether you are willing to have radiation or not and whether you can "stand" to have tumor in your head and w&w.. some can and some can't ...
I don't know anything about Dr in TX so no help there,, just some thoughts on the whole decision process which in itself is quite overwhelming as it is such a huge decision. You seem to have time on your side though as it appears to be on the small side and you don't have many symptoms other than the hearing loss..of course I am not a Dr. so this is just my opinion for what it is worth! Good luck, keep us posted.. Jane
