Oral Cavity and Pharynx Cancer | Did You Know?


[MUSIC] Did You Know? Video Series from
the National Cancer Institute: Oral Cavity and Pharynx Cancer Did you know that men are
twice as likely as women to be diagnosed with oral
cavity and pharynx cancer? Cancer of the oral cavity and
pharynx is cancer that forms in the mouth or throat. Oral cavity cancers can
occur in: the lips, gums, front part of the tongue,
salivary glands, and inner lining of the cheeks, the roof
and bottom of the mouth and the area behind
the wisdom teeth. Cancers in the pharynx,
or throat, can occur in: the nasopharynx, or the part of
the throat behind the nose, the oropharynx, which
includes the tonsils, the base of the tongue, the back
of the roof of the mouth and the side and back walls of the
throat, and the hypopharynx, or bottom of the throat. Oral cavity and pharynx cancers
are more likely to develop in the tongue, oropharynx, tonsils,
gums and salivary glands. Because smoking rates have
decreased, new diagnoses of smoking-related oral cavity and
pharynx cancers have dropped. However, cancers associated
with human papillomavirus, or HPV, are on the rise. Approximately 70 percent of
cancers in the oropharynx are caused by HPV infection. Human papillomaviruses
are a group of over 200 related viruses. More than 40 HPV types
can be easily spread by vaginal, anal, and oral sex. Persistent HPV infection causes
cellular changes that can lead to different types of cancer. White men have the highest rates
of new cases for oral cavity and pharynx cancer,
followed by black men and American Indian
and Alaska Natives. These groups also
experience major differences in survival rates. The five-year relative
survival rates are about 68 percent for white men, but
only 45 percent for black men. This means that five years after
diagnosis with oral cavity and pharynx cancer, 68 out of every
100 white men will still be alive, but only 45 out
of every 100 black men will survive that long. Some of the gap in
survival rates is because black men are often
diagnosed at a later stage, when the cancer has spread
to other parts of the body. One way to improve survival
is through early detection. Some of the signs of oral cavity
and pharynx cancers include: a sore throat that does not
go away; a lump in the nose, neck, throat, mouth, gums,
or lips; trouble breathing, speaking, chewing, swallowing,
opening the mouth fully, or moving the tongue or jaw; ear
pain; or a change in voice. If you experience
any of these symptoms, talk with your doctor. It is important to be diagnosed
and treated early to improve your chances of survival. Take steps that may
reduce your risk of oral cavity and pharynx cancer. Eat well. Be active. Don’t smoke or use tobacco. Avoid alcohol. Get vaccinated against HPV. If you have been diagnosed with
oral cavity and pharynx cancer, visit cancer.gov/clinicaltrials to learn about clinical
trial treatment options. Speak with your doctor to make a
decision that is right for you. For more information on oral
