Go ahead and get it checked! I have anxiety attacks too. Worrying about the possibilities is way worse than the appointment to find an answer, truly. Mine was a tongue ulcer that would not heal, I was not even thinking cancer, and here I am. Then a spot did not seem to be healing right after the surgeries, and here I am again. It is frightening, but the alternative would be much worse.
