Millie,
Click on "Introduce Yourself" in the main menu and go down the topics about 2/3 of the way to a post from "traceemail" that has the title "My mom" her mothers surgeon was in Florida and several other doctors told them the tumor was inoperable and she found a surgeon in Florida that was able to remove all the cancer with clear margins even though it was attached to major veins in the neck. Her post gives lots of information that I think you can use.
I hope this helps. I have read practically all the posts on this site and when I saw yours it reminded me of her situation.
I will be keeping your family in my prayers. Don't give up, get more opinions....but do it quickly.
