Well now I am confused- yet "AGAIN"

I have read protocols for treating every stage of scc on various Cancer Center websites. [that's not to say they are all the same protocols] Also, our surgeon\oncologist was prone to quote "protocols" to us when I would question him about John's tx. plan. His Chemo Doc does the same thing.
H- my husband did have radiation starting 6 weeks after his surgery- altho his neck dissection showed no nodes involved [the 1st go round] The surgeon said his floor of mouth tumor was a really aggressive kind. I don't know how they know that. I thought all SCC were the same, just in different areas of the mouth, but I guess not. To fully understand this disease, you would have to devote years to study and research. At age 65, I find I must leave that to others and do alot of trusting [and praying] now. Very scary. Amy
