I have and if I were younger I would probably try that first. I'm 64 and if radiation doesn't shrink it or even if it does, it could still grow back and I agree with my surgeon that I don't want to be much older and have to go through the craniotomy. They are going to leave 5% of the tumor so that they have a barrier "flap" to help keep spinal fluid out of my sinus cavity. The leakage would put me at risk for meningitis which is a threat for me. Not having a spleen makes it hard for your body to fight off certain infections, meningitis being one of them. I keep up on my meningitis vaccines for that reason.
So I might have to have radiation a year post op just to keep that 5% from growing.
