Have you looked into the gamma knife? I think it's known by many names, but the main purpose is to cut off the blood supply to the tumor with radiation on either side (it's non invasive and is a combination of laser and radiation technology) which causes the tumor to wither and die. It wasn't an option for my sister as she had gone through the entire battery of radiation and had her "lifetime" supply of radiation at the point we thought this would have been an option. She is now under the care of doctors at Duke Medical Center in North Carolina and is part of a clinical trial - she's 2 years out from diagnosis at this point. Best of luck - I know how difficult this is. We call the outbursts "tumor talk".
