Hi Bryan, my oral cancer started out as Leukoplakia - no one told me it was pre-cancerous until it was too late unfortunately. I don't think it started out as OC though; at first it was just a white patch, but then over a period of a few months a red bump developed underneath it. Do you notice if there is any bump under the spot? I think that is the point where it turned into cancer, from what I can tell. I have a very high tolerance for pain, so I blew it off until it was too painful to eat. I got a dentist family friend to look at it, who then sent me to an oral surgeon. He didn't want to be the one to give me the bad news, but later on he said he knew immediately that it was cancer, so your dentist might be able to at least give you an opinion while you wait to see an oral surgeon/ENT. Where is your leukoplakia? Mine was on the left side of my tongue. Good luck! Let us know how it goes.
