The only way to know for certain would be to ask the doctor. My mom died of Lung cancer 2 years ago after a 2.5 yr battle with NSCLC. She had liver mets and back in the beginning I asked her oncologist if we could look into Cyberknife for the mets. I had talked to a doctor at Stanford that does cyberknife and he told me they could do the liver mets. Well my mom's oncologist told me they can not use cyberknife on the liver I told them they could and that I had talked to the doctor at Stanford. Well he still argued with me about how they only use cyberknife on the brain. We argued for 20-30 minutes before he finally admitted to me that his speciality is chemo therapy and he really does not know much about the different radiation treatments.... humm why couldn't he have just mentioned that to me in the first place?
She never got the cyberknife as she had Kaiser as her insurance and they stalled around so long that by the time we got them to give us a copy of her latest CT to send to Stanford it was months later and she then had too many liver mets for them to do cyberknife.
My advice is don't assume the oncologist know everything if you read about something ask them and push for answers when necessary. Do not let them intimidate you as trust me they are not even close to being God. I should know as I have worked with them for 27 yrs. They are human just like you and I.
