Tobacco and Alcohol May Cause Oral Cancer.
We all know that tobacco and alcohol can cause lung cancer. Do you know it may also cause oral cancer? Oral cancer is a subtype of head and neck cancer is any cancerous tissue growth located in the oral cavity. When you see sore, lump, or ulcer in the mouth, or have some Chewing problems, Mouth sores, Pain with swallowing, Speech difficulties or some other bad signs with your oral, please go to your dentist immediately since it may a sign of order cancer.
Tobacco.
Conventional cigarette smoking and other tobacco use are associated with about 75 percent of oral cancer cases, caused by irritation of the mucous membranes of the mouth from traditional smoke and heat of cigarettes, cigars, and pipes. Tobacco contains over 60 known carcinogens, and the combustion of it, and by products from this process, is the primary mode of involvement. Use of chewing tobacco or snuff causes irritation from direct contact with the mucous membranes.
Tobacco use in any form by itself, and even more so in combination with heavy alcohol consumption, continues to be an important risk factor for oral cancer. However, due to the current trends in the spread of HPV16, the virus is now considered the primary causative factor in 63% of newly diagnosed patients.
Alcohol.
Alcohol use is another high-risk activity associated with oral cancer. There is known to be a very strong synergistic effect on oral cancer risk when a person is both a heavy traditional smoker and drinker. The risk is greatly increased compared to a heavy traditional smoker, or a heavy drinker alone. Recent studies point to alcohol-containing mouthwashes as also being etiologic agents in the oral cancer risk family. Constant exposure to these alcohol containing rinses, even in the absence of traditional smoking and drinking, lead to significant increases in the development of oral cancer. However, lot of studies summarize that alcohol-containing mouth rinses are not associated with oral cancer. The American Dental Association said �the available evidence does not support a connection between oral cancer and alcohol-containing mouth rinse� A science study suggests that acetaldehyde (a break-down product of alcohol) is implicated in oral cancer. This study specifically focused on abusers of alcohol and made no reference to mouthwash. Any connection between oral cancer and mouthwash is tenuous without further investigation.
