I think it's more of a liability + safety issue as most inoperable tumors are located near or close to vital structure(s) where if altered or manipulated may cause serious injury or death. It really doesn't matter about what cool new tool you may have that can remove "more" of it. Then there is also the fact that tumors have a blood supply (bleeding risk could be fatal in certain areas of the brain).
