How can anyone say that radiation is not the best option to take? My motto has always been "quality of life over quantity of life!"
People get a brain tumour and immediately think.. GOTTA HAVE THIS THING OUT. Trust me, I felt that too. I wanted to cut it out myself. I would look in the mirror and only see ugly. I would see the reflection being one of a distorted face with a monster on one side. Once I realized the morbidity of nerve function from surgery, I knew I would not choose that. Yes there is a chance the tumour could turn malignant over time, but as I say, "Quality of life over Quantity" :) Plus, you have a better chance dying in a car crash then it turning malignant,,, do you never drive because you may crash??? Think about it.
If your doctor says your tumour is too big to do radiation with cyberknife then show him the two MRI reports below and tell him/her to think again.
