dude, sorry about your mom. You may want to inquire into some of the stuff that UPMC is doing in Pittsburgh, for several years now they have been working with single point gamma radiation treatment which supposedly can treat a tumor without causing as much damage to surrounding tissue. I'm not a doctor so I don't know if it will help in your situation but it may be worth a look. Good luck, and for those of with religious inclinations we will keep you and her in our prayers.
