One more thing -- I've been reading a lot lately about nuitrition and the fight against cancer spread. I realize there is a lot of bogus info out there and it's hard to separate the wheat from the chaff, but some of this stuff also makes a lot of sense at least to my small mind (i.e. propping up your immune system with good eating, etc.)... Might be worth considering some of these "alternative" approaches in addition to all the familiar stuff, if you haven't already...
Love ya, kid... hang in there...
