Answer:
Tobacco use is responsible for nearly one in five deaths in the United States.”
“ (a) For each 1,000 tons of tobacco produced, about 1,000 people eventually will die. Lifelong smokers on average have a 50 percent chance of dying from tobacco-related illnesses, with half of these dying before the age of 70.”
The single greatest risk factor for oral cancer is tobacco. Oral cancer cases are seen in patients who do not use tobacco, (see the HPV connection link on the home page navigation bar) and there are also people who develop the disease with no known risk factors. The numbers as a percentage of these is are very small. Tobacco, in spite of these other causes and unknowns still is the largest contributor to the development of oral cancers. All forms of tobacco have been implicated as causative agents including cigarette, cigar and pipe tobacco, as well as chewing tobacco. It is important to differentiate between conventional loose leaf (traditional) forms of smokeless tobaccos and the newer types such as snus, as evidence from outside the US suggests that there is a significant difference in risk. But it must be remembered that these products are currently a very small part of the US smokeless tobacco sales number, and the US products that mimic the Swedish snus products are NOT the same product, and the data cannot be transferred from one to the other interchangeably. Studies need to be done on US products to see if they actually have reduced risk. In India and Sri Lanka, where chewing tobacco is used with betel nuts and reverse smoking is practiced (placing the lit end in the mouth), there is a striking incidence of oral cancer – these cases account for as many as 50 percent of all cancers. (WHO)
Tobacco can damage cells in the lining of the oral cavity and oropharynx, causing cells to grow more rapidly to repair the damage. Researchers believe that DNA-damaging chemicals in tobacco are linked to the increased risk of oral cancer, according to the American Cancer Society.
