Cyberknife vs. traditional radiation

Hello all,
I have on and off these boards since 2008. I have been fighting the beast since then with little break. I just had surgery to try to remove four tumors that chemo didn't get. Unfortunately one was in a life threatening place and could not be fully removed.
My Doctor is suggesting radiation and chemo. I had this same treatment last summer for a para-aortic lymph node. I was told it worked, but later found out it didn't. They removed the para-aortic growth two weeks ago....
Now, I don't know what to do. I know a lot of ladies have had success with cyberknife. It is not offered in my area. I mentioned it to my oncologist at one point and he just kind of laughed....He is not one you can easily talk to.
I am supposed to start chemo next week already. I am so tired. They removed my spleen, gallbladder and a few other small cancers.
I know Cleveland Clinic and University Hospital do cyberknife, as do a lot of other places, but I'm not sure what to do. I'm not sure if my radiation oncologist will tell me the truth, since he doesn't do it....
Any input greatly appreciated. I am beginning to lose hope. By the way, my CA125 was only 26 when all the new cancer was discovered.
