hello again, i sit here and play over in my head time after time the words of my dad's ENT surgeon.. one thing he did say was that after going in and removing my father's tumor which included 3/4 of his tongue he did have perinueral invasion, but they got clear margins, and lymphnodes were clean.. all of this is so confusing at times and i do need to stop looking on the internet.. can anyone explain to me the positive side of clear margins and clean lymphnodes? i do see by doing some research that perineural invasion is "not good"..
thank you all again!
