Hi Laura,
Welcome to the OCF aand good luck tomorrow.
I am one of the few members here that did not have radiation and/or chemo. The reason for this was that I was a Stage I with 30 clear nodes from my neck and no cells in my tongue resection. It appears that my biopsy got "it" all. After spending the last 7 plus months on this website, it appears to me that the vast majority of members have had either chemo or radiation or both.
I was lucky that I found my scc so early and thankful that I am a dentist and as a result acted so quickly. Believe me when I say that before all this happened, I didn't know much about oral cancer. What I have learned is that if I had any lymph node involvement or any cells in the disection, I would have gone for the "works" and used anything and everything that was available.
A second opinion, as suggested by John, may not be a bad idea. If you are interested, please email me and I can give you the name of my surgeon at Fox Chase in Phila. It's not that far from you.
My prayers are with you.
Jerry
