Smoking in relation to oral cancer
According to the World Health Organization, eight and a half million years of life are lost each year worldwide due to the effects of tobacco. These years correspond to 700,000 people who lose their lives to tobacco.
Its use is one of the biggest
challenges the world faces today concerning public health. Smoking is
just as devastating to the oral cavity and teeth as well.
Experts have concluded that cigarettes contain up to 60 chemical carcinogens that lead to incurable cancers of the pharynx and larynx. Oral cancer along with pharyngeal and laryngeal cancer represents the 6th most common form of cancer in humans and has a serious prognosis with a 5-year survival rate of 40% -50%.
The most important effects of smoking in the oral cavity are oral cancer and precancerous disorders, increased severity and extent of periodontal disease, and poor wound healing.
According to the Council of European Dentists (CED), a smoker's life cycle for each cigarette smoked is shortened by about 5 minutes. In other words, he is in danger of living 10-15 years less than expected. But the cost is not just in life. Conservative estimates put the cost of smoking in Europe at 25.3 billion euros a year, while the social cost of lost productivity is 8.3 billion a year! Scientists are sounding the alarm and stressing that by 2030, unless there are dramatic reductions in tobacco use, the number of deaths worldwide will rise to 10 million deaths a year.
More than 80% of patients with oral cancer are smokers.
The good news is that quitting smoking for more than 10 years reduces the risk of developing oral cancer by half.
