Hello. I am new to these forums and must admit I am scared of cancer. After watching my grandfather die of throat and lung cancer the thought is horrible. But I have noticed a strange smooth spot in my mouth on the cheek, near the back set of left molars and inbetween top on bottum. It feels oddly dry but is flat, painless, and barely raises. It has been there for five days and I cannot tell if it is getting better. I will go so a doctor in 3 days if it is not healed. I am a smoker, the age of 19, and have been smoking for 5 years. I know it would be rare for me to have oral cancer because I am so young. Please dont tell me I need to go to the doctor and get checked...I know this. The spot in my mouth is about the size of a nickel or quarter.. It has a very strange rough ring around it. It feels different at the touch of the tough. It's not numb. It's somewhat red, I think only because Ive been playing with it. If anyone can relate to having something like this, please do tell. It could be from an infected tooth maybe, or chewing on it in my sleep.
