What are ways you can get mouth cancer?

Mutations: Cancer occurs when cells mutate, divide uncontrollably, and do not die off. The mutation can occur naturally, but more often from an outside source. Very high doses of radiation can be a cause, but more often in the mouth it is cigarette smoking and use of smokeless tobacco. Use of alcohol while smoking increases your chances even more.

Oral cancer: Any chronic habits such as alcohol or tobacco, fractured teeth and dentures, and genetics.

Most common: Most common causes are heavy drinking and heavy smoking. See ENT doc for treatment.
