About Oral Cancer
The term oral cancer includes cancers of the mouth and the pharynx,
part of the throat. About two-thirds of oral cancers occur in the
mouth and about one-third are found in the pharynx.
Oral cancer will be diagnosed in an estimated 30,000 Americans this
year and will cause more than 8,000 deaths. The disease kills
approximately one person every hour. Oral cancer is the 6th most
common cancer in men and the 14th most common cancer in women.
Oral cancer can spread quickly. On average, only half of those
diagnosed with the disease will survive more than five years.
Oral cancer most often occurs in people over the age of 40 and affects
twice as many men as women.
Lower Your Risk
Most oral cancer is preventable. 75% of oral cancers are related to
tobacco use, alcohol use, or use of both substances together. Using
both tobacco and alcohol puts you at much greater risk than using
either substance alone.
- Do not use tobacco products: cigarettes, chew or snuff,
pipes or cigars. Tobacco in all forms plays a role in oral cancers.
- If you drink alcohol, do so only in moderation: Excessive
alcohol use can increase your risk of oral cancer.
- Use lip balm that contains sunscreen: Exposure to
sunlight is a risk factor for lip cancer.
- Eat plenty of fruits and vegetables: Eating lots of
fruits and vegetables as part of a low-fat, high fiber diet may help
reduce cancer risk. The National Cancer Institute suggests eating at
least five servings of fruits and vegetables a day.

It is important to find oral cancer as early as possible when it
can be treated more successfully. An oral cancer examination can
detect early signs of cancer. Oral cancer exams are painless and quick
— and take only a few minutes.
Your regular dental check-up is an excellent opportunity to have the
exam. During the exam, your dentist or dental hygienist will check
your face, neck, lips, and entire mouth. Some parts of the pharynx are
not visible during an oral cancer exam. Talk to your dentist about
whether a specialist should check your pharynx.
The Oral Cancer Exam
An oral cancer exam is painless and quick — it takes only a few
minutes. Your regular dental checkup is an excellent opportunity to
have the exam. Here’s what to expect:
- Preparing for the exam: If you have dentures (plates) or
partials, you will be asked to remove them.
- Your health care provider will inspect your face, neck, lips and
mouth to look for any signs of cancer.
- With both hands, he or she will feel the area under your jaw and
the side of your neck, checking for lumps that may suggest cancer.
- He or she will then look at and feel the insides of your lips
and cheeks to check for possible signs of cancer, such as red and/or
- Next, your provider will have you stick out your tongue so it
can be checked for swelling or abnormal color or texture.
- Using gauze, he or she will then gently pull your tongue to one
side, then the other, to check the base of your tongue. The
underside of your tongue will also be checked.
- In addition, he or she will look at the roof and floor of your
mouth, as well as the back of your throat.
- Finally, your provider will put one finger on the floor of your
mouth and, with the other hand under your chin, gently press down to
check for lumps or sensitivity.
