Carcinogens: It is the carcinogens in the tobacco that leach into the soft tissues of your mouth and cause the changes on a cellular level that result in cancer cells forming.

Tissue contact: Smokeless tobacco is a "pinch" held between the lip and gum. The constant contact on the tissues allows the harsh and carcinogenic chemicals in the tobacco to be absorbed into the tissues and then cause mutations in the cells that become cancerous.

Duplication error: Cancer is basically an error in the genetic duplication of a cell. This can be caused by radiation, virus, chemicals, and other factors. With smokeless tobacco you have a carcinogenic chemical combined with irritation( which means statistically more cells are duplicating so you have a greater chance of error).

Chemicals in Tobacco: Over time the nicotine in the tobacco leaches out of the smokeless tobacco and decreases blood flow to the cheek and gum mucous membranes. This mucosa becomes more permeable to the 200+ cancer producing chemicals in tobacco. If you drink alcohol, the alcohol increases carcinogensis by extracting the carcinogens and enhancing their penetration into the mucosa. Stop if you can, or get help to stop.
