Causes Of Oral Cancer
There are certain risk factors that are responsible for causing mouth cancer. These include smoking and chewing tobacco, poor nutrition, QAT chewing, alcohol consumption, and many other.
Smoking and Alcohol Consumption
Smoking and alcohol consumption are the most common source of oral cancer. Cigarettes and other tobacco products, like cigars and other products are important agents. Too much consumption of alcohol causes mutation in genetic material and causes cancer. The risk of mouth cancer is significantly increases addicts especially in tobacco and alcohol addicts.
Studies shown that heavy smokers who smoke 35 cigarettes per day have a chance of developing oral cancer 5 time more than than someone who do not smoke or drink.
On the other hand a person who only drink 30 liter of alcohol per week but do not smoke, are also more susceptible to these disease.
In person with the combination of both habits (smoking and alcohol consumption), the risk of developing mouth cancer is 40 times higher.
Chewing Tobacco And Oral Cancer
Chewing tobacco is much more dangerous than smoking and person with such habit have more risk of developing mouth cancer because inner linings of the mouth is directly exposed to the carcinogens.
Other types of tobacco use includes, the use of snuff and snus that popular in Sweden, which is attached under the lip, where it was gradually added into the bloodstream.
Chewing Betel Nuts
Betel nuts are hooked seeds taken from the betel palm. These are chewed by Southeast Asian ethnic groups from Sri Lanka and India. These contain a chemical similar to caffeine. Betel nuts contain cancer causing substances that raise the risk of mouth cancers.
Who chew betel nuts and tobacco together is of course at more risk. Because of this bad habit mouth cancer is much higher in Sri Lanka racial groups and indian ethnic (racial) groups than other population.
QAT plant found in southern Arabia and also in African countries which have mild stimulating effect. It is green leaf plant. It can be chewed in combination with tobacco. QAT and tobacco both together increase the risk of mouth cancers.
Cannabis Smoking And Mouth Cancer
Cannabis (Marijuana) smoking is another important causative agent of mouth cancer. Regular cannabis smokers have more chancechane of developing mouth cancer because cannabis contain higher levels of Tar than tobacco smoke which is carcinogenic.
Exposure To Viruses And Mouth Cancer

Poor Oral Hygiene
Poor oral hygiene may, with gum diseases, without regular brushing or flossing, the tainted teeth and contaminated equipped dentures increase the chance of developing mouth cancer.
Excessive Exposure To Sunlight
