When I originally presented with scc on the tongue they did a partial glossectomy, then due to the depth of the tumor, a neck dissection, took out 72 lymph nodes, 1 positive...no chemo no rad's...within 8 months, the lump on my neck that I'd been pointing out to my surgeon started protruding so they could visualize it not just feel it...it was back! Now they decided to do the chemo and rads...they radiated both sides of my mouth and neck just to be sure and the chemo was to get any cells elsewhere in my body...my point is I was always uncomfortable in the beginning with no chemo/radiation and I was right...don't be afraid to ask the questions as to why they don't want to do it and don't be afraid to get a second opinion!
