Dentistry/chewing tobacco/mouth cancer


I used chewing tobacco rarely  from 20 to 30 years old (about 20 total cans over that time). Now I am 40 years old, have not used in 10 years. What is my estimated relative risk (compared to the overall population) of getting mouth cancer?

Hi David, it is very difficult to estimate the risk potential of cancer. It follows a rule called "ALL OR NONE PRINCIPAL" IT means that if a person cunsumes very less tobacco he might have cancer and a person having tobacco might not have cancer atall.Only this is clear that tobacco does cause acrcinogensis and i would suspect very less chances of cancer if you don't consume it any more.
