Hi Belle and welcome.
This site is for Acoustic Neuroma (benign brain tumor) patients..... and many of us (myself included) have had Cyberknife for our AN's.
Cyberknife has a terrific online discussion forum (like this one) that has doctors volunteering their time to answer questions about CK for all kinds of ailments:
www.cyberknife.comIf you do a post there in the "Other" forum/section, Dr. Medbury, Dr Spunberg or others will be able to help answer specifics for you. (you can tell them the ANA forum suggested you ask them directly).
I'm sorry to hear about your auntie. I send healing huggles and wishes for her wellness.
Please try the Cyberknife forum. I truly believe they will be able to answer directly-related questions for you.
Wishes and prayers for auntie. Please hang in there... she is very lucky to have you doing research for her.
