Would you do WBR a Second Time?? Advice ASAP Please

Just a bit of personal information, in hope that it may help your daughter:
I was diagnosed with 5 brain tumors in early 2010. The oncologist wanted me to have wbr, after intense reseach, i refused wbr and decided on cyberknife; at that point i had an unfortunate event however [the cybetrknife place treated only two of the tumors- made a mistake]. I went alsewhere and got the other two treated. I was then put on hercepting, tykerb, xeloda, faslodex and zometa. Three of the five tumors have completely gone and the other two are barely visible. However one new one surfaced since and is also getting smaller [3mm].i am on my way to cyberknife it as well.
How many tumors does your daughter have? It is my understanding that while it is stated that gamma knife can only treat up to eight tumors, i have heard that "it can be stretched" to more tumors. Wbr? I made up my mind that it would be the very last thing i would ever do if ever! Dont stop trying to find the best thing for your daughter. Patricia
