In India, it is quite common to chew types of tobacco so the oral cancers make up nearly forty percent of all the types of cancer in the country. This is high when compared with the United Kingdom, which is around four percent. Note that this doesn’t mean that the only way to get oral cancer is from chewing tobacco.
Smoking cigarettes is responsible for nearly seventy five percent of cases involving some type of oral cancer, because smoking cigarettes causes irritation of the tissues through the smoke, and also the high heat. This irritation of the tissues leads to the ruining of the cells, and eventually leads to oral cancers. Oral cancers are, as with lung cancers, largely preventable and the best way to prevent any further damage to the mouth is to quit now and forever.
