To reduce your risk of head and neck cancer,
Avoid smoking cigarettes, cigars, or pipes. If you smoke, get the help you need to quit.
Avoid chewing tobacco and dipping snuff.
Avoid excessive alcohol use. Besides being a risk factor by itself, chronic or excessive alcohol use multiplies the risk of head and neck cancer in people who also use tobacco. If you drink, aim for no more than one drink a day if you are a woman and no more than two if you are a man.
Practice good oral hygiene.
Visit your dentist regularly. A dental checkup includes an examination of the inside of your mouth.
