What are the causes of Oral Cancer?
Following are the risk factors for Oral Cancer:
Tobacco use is considered to be one of the biggest risk factors associated with the development of oral cancer. It is a broad category of risk factor that includes tobacco chewing, smoking pipes, cigars and cigarettes. People who regularly drink alcohol or smoke tobacco are at an increased risk of mouth cancer than those who do that occasionally or do not indulge in such activities at all. Other factors that are believed to contribute to the development of oral cancer include:
Family history of any type of cancer is also believed to be one of the risk factors behind development of oral cancer
Previous history of oral cancer
Chronic exposure to the sun
Infection with human papillomavirus (HPV), a sexually-transmitted virus, may also increase the risk of oral cancer
In addition to the above factors, males are more likely to develop oral cancer than females. The clear reason behind this is not understood. Overall, a person who smokes is six times more likely to develop mouth cancer. On the other hand, smokeless tobacco users are 50 times more likely to develop cancer of the lips, cheek or gums. Despite all the risk factors, almost 25 percent of oral cancer cases still affect people who do not chew or smoke tobacco and those who drink only occasionally.
