Thank you Sue.
We are going to give him the very best of everything we can while we can. He so dearly wants to be at home, and so we will arrange for hospice care there, with all palliative measures available to us. My sister and brother are coming to NY tomorrow.
I can't even think about it now, but for anyone else reading this who is afraid to go to a doctor to find out what that thing is in your mouth - please don't put it off, not even for a minute. My brother started noticing something in his mouth, a canker sore he thought at first, in October of 2007. It grew and grew but he never went to see anyone until late February, and he was finally diagnosed March 17, 2008. Please don't wait, even if you are terribly afraid.
Keep up the good fight everyone. It is beatable, you just have to get to it in time.
