Hi Sueoelke,
I am sorry to hear about your tumor regrowing and hope you find the team and treatment that brings you success in treating it once and for all.
Unlike you, I did not have surgery prior to my radiation, but I was also needing guidance and experienced voices regarding which path to choose to treat my AN. I originally went to see the "closest" doctor to me, someone within my medical facility's organization, and recommended to me by my ENT. (I had to wonder if my ENT was bound to recommend this certain doctor.)
But before I met with him, I found this site, read for hours here, and learned more about my tumor than I had ever imagined I could. I also listened to two interviews on the site myacoustic.org, that were completely enlightening for me. (Thank you, Francesco)
By the time I met with this doctor, I knew that I wanted someone VERY experienced in ANs, not only the for radiosurgery itself, but with updated equipment, and support during the (possible years of) "recovery." He turned out not to be the doctor for me.
I ended up choosing radiosurgery with a doctor that is an hour away from me. It was a decision I was very comfortable with. I wish I had advice for you specific to St. Luke's, but I don't. I will say though, that I have read many of the ANers here say to choose a doctor with a LOT of experience with treating ANs, as you will find the most success with them.
I wish you the best of luck and good health going forward.
Sincerely,
sunny
