Can you get mouth cancer from chewing skoal for only a short period?

Define Short term: What is short term? Months, few years, few days, weeks? There is high and direct correlation between smokeless tobacco and oral cancer. The chances are you are good and don't worry too much about it. Your dentist should do oral cancer screening every 6 months. We have kits too so please ask your dentist every 6 months you see him or her to check your mouth for oral cancer. Ask for the screening.

Yes: The longer the use, the higher the risk. But, no one knows when the tobacco can do enough irritation to start that one cell to multiply malignantly. Do you want to gamble?
