What causes oral cancer?
Tobacco (cigarettes, pipes, cigars, chewing tobacco, and snuff) is the most common cause of oral cancer. Combining tobacco use with heavy drinking can also foster the development of oral cancer. Bad hygiene, prolonged irritation of the oral cavity, and extended exposure to strong sunlight on the lips are among other causes of the disease. Many dentists believe vitamins A and E can help prevent the acquisition of oral cancer.
