As indicated in my signature block below, I was recently diagnosed with a medium-large AN.
I feel negatively about traditional surgery, so that's not for me. My objective is to focus on the tumor, so I am not worrying about preserving my left ear hearing. So perhaps either Gamma Knife or FSR are options for me.
Status on GK --- I have studied GK. I live very close to a Gamma Knife center, where the neurosurgeon has done over 400 radiosurgeries including about 50 AN's. My research included a few hours of consultation with the GK staff.
Status on FSR --- This week I am going to be focusing on completing my study of FSR, including a special focus on Johns Hopkins 5-session FSR ......including consultation appointments there on Friday.
If any inputs, please send them, because this week is getting very close to a final decision for me.
Thanks, Bob H
