Oral cancer

I have been a one-pack-a-day smoker since I was 18. I'm 22 right now, and I quit two months ago. I started noticing a very tiny white mark (maybe a little over 1 mm) on the side of my cheek just a few days ago. I went to the dentist last week and he said that everything was fine. Is it likely that it can be oral cancer? Can I get it at my age and with my history of smoking, even though it was for a relatively short period and I recently quit? There is no history of oral cancer in my family and I rarely drink alcohol. Also, how quickly do cancerous patches in the mouth grow?

Very unlikely at your age. Congratulations on quitting smoking. I hepe it is pretty much gone now but if not, give it another week. I'm sure it will resolve itself.

Good luck.

It was most likely just a sore.  Give it a week or two to go away or at least get smaller.  If it gets larger, I would see your dentist.
