Wait see what the results say. Chances are it was nothing but the biopsy would be definitive. Do keep an eye on the area after to make sure it heals etc... I am surprised the one dr. didn't see it when the other dr obviously did in order to remove it. Rude tends to be the case with some specialists - often they are brisk and busy and do seem to have that blow off air. As long as you are clear on what you want to have done and what your concern is, then they will usually follow through on the request ( its more of a save your hide situation - if he or she doesn't and it turns out it was cancer - it could mean trouble for them ) My dr. initially was nice but distant, he's warmed up over time I think too that since all he does is oral cancer and surgery that he sees a lot of scary/sad/bad news stories. Maybe this is his way of dealing with the ins and outs of it. And he has every right to be a snob as he is the best of the best.. I told myself I don't need a shoulder to cry on - or a hand holder, I need a guy who is damn good at what he does. ;o) Anyway... wait... it's not fun, but start calling at week two. Usually its not more than 14 days.
fingers crossed for you.
