Don,
This is such a tough time for you and your family, I am sure. I know, emotionally it was the hardest for me..that time between diagnosis and treatment when you are making life and death decisions between a miriad of options and approaches. I feel your pain, believe me.
I guess the question you have to ask yourself is, "Have I done all I can to answer the what ifs to the extent that I can." If you are comfortable with the answer, then make your decision and go with it.
Bill had a similar tumor and dx but with no nodal involvement. We were not offered induction chemo..just a very aggressive radiation schedule (hyperfractionated...2x day) and a weekly chemo (see siggie.) This was by a comprehensive cancer center - Moffitt in Tampa Florida.
I note that you mention a tooth needing to be pulled yet in your signature. I think you are already aware that that needs to happen before your treatment starts..right?
Sorry we are all giving you different approaches, I know it would be easier if there was one simple answer. Good luck with all of this. You will feel better (at least mentally) once you make that decision and get going with treatment.
