Hi C! It isn't cancer until a biopsy says so. You sound upset & understandably so. Take a deep breath & try to relax. Get to an ENT that is experienced with oral cancers, preffereably one at a major cancer center & get checked out. If it's not cancer then you can get treated for whatever it is & if it is you'll be in the right place. I hope it's not cancer but if it is you need early diagnosis & treatment. Try to relax, but make it happen! Let us know how you come out either way. Erik
