Raymond,
You and I are about the same age and our children's ages are also similar, mine are 10, 13, and 15. I had surgery to remove my cancer in October 2000, all has been clear since that date. I have gone through several procedures to rebuild my upper jaw and place dental implants. From my perspective, there is light at the end of the tunnel. As you can see from the previous posts, there are many resources here for you to draw from. Keep your spirits up and keep on fighting.
