CHANCES OF MOUTH CANCER IN A 23 YEAR-OLD?I have been smoking citaergts, probably anwhere from 1/4 pack-a-day to 1 pack-a-day since I was about 17. I am 23 now.I plan on quitting completely by the time I am 25, and I know that I will. However, I would just like to know how likely it would be for me to develop mouth cancer at my current age. Is it likely at all? I know it isn't  completely impossible  but I am trying to realistic. If anyone has any actualy medical statistics I would greatly appreciate it.And, please, I know most  smoking/cancer  questions get bombarded with replies like  The best way to smoke is to not smoke!  and  Smoking WILL kill you sooner or later! Please, keep the preachy stuff away. I am looking for an honest and knowledgable opinion.Thanks in advance.
