Rob, you are wise to do your homework. You will be better prepared to make a decision after you get the results of the PET/CT. 1. I, myself, so far have been very, very fortunate. I did have a modified ND, and I was very thankful for it! It gave me a great sense of confidence that the cancer had been removed by my original surgery and hadn't spread, and that, then, most of the metastatic pathway had been removed. 2. All cases are different. 3. With all of the treatment and diagnostic testing you have had, and with your living in Boston, you obviously are surrounded by knowledgeable professionals. LISTEN TO THEM. 4......and I am betting that you hear this more than once: Don't play much of a waiting game with SCC. If it were MY neck, I would run, not walk, to the operating room. But that's just me. Listen to your doctors, and while the final decision is yours to make, remember that you are not as prepared to make it as they are. XOXO
