Oral Cancer is a very rare cancer, and most of the people that get oral cancer are very heavy smokers/drinkers and over the age of 50. BUT there are getting to be more oral cancers in non-smokers under the age of 50...so I would get it checked out by an ENT and even if he says it's nothing, I would keep a close eye on it anyway...because ENT's can be wrong.
The first thing you need to do is QUIT SMOKING!!!!! Don't do it. Quit NOW and don't do it again! I have talked to sooo many people on these message boards that were smokers and now have oral cancer and lung cancer and now they're kicking themselves for smoking all those years. Just quit.
The next thing to do is make a regular dental appt. at least once a year. Not only because they check for oral cancer in the check-up, but because oral health is important to the rest of your body. Very important...so keep your teeth clean.
I would still go see an ENT and have him look at it because it's better to be safe than sorry.
