Theresa, you sound so much better! I am glad you are up and doing things, but please, do not over do it. Thi doctor sounds good, and the Gamma knife is a very neat little tool. It is used a lot in vascular surgery. It destroys the alien within, cuts way dowm on the bleeding and is so accurate it doesn't harm healthy tissue. This is a good thing, so it is natural to be nervous, but this is good neews to be near someone that can do this type of surgery. Keep it up girl! Let them do all the tet, let them find the liens every nook and crany, then they can go in remove most of it and disble what they can not get, you will be feeling so much better soon.
You are an amazing inspiration.
