Eating, drinking, speaking, and smiling – our mouths play a significant role in our overall health and well-being. We often undervalue the importance of our mouth and oral care. This is probably why oral cancers are often overlooked and discovered too late in their development.

The mouth (oral cavity) can easily be examined, suggesting that it should be easy to detect cancer of the oral cavity at an early stage. Yet, in 2020 an estimated 53, 260 new persons developed oral and pharyngeal cancers and 10,750 persons died due to this disease in the United States. Unfortunately, incidences of these cancers have increased in the last 20 years. The overall 5-year relative survival rate of these cancers in the U.S. is 66.2 percent. Only 29 percent of these cases are detected at localized stage (confined to primary site only), when the 5-year survival rate is 85 percent. This means that half of the current deaths can be prevented by starting a mechanism to detect these cancers at an early stage.

In fact, the majority of these cancers can be prevented by a life-style change. Let’s get empowered to effectively fight this dreadful disease.

Who is More Likely to get Oral and Pharyngeal Cancers?

Despite tremendous advances, medical science cannot predict the chances of getting any cancer in a specific person, but the rate of new cases of cancer (cancer incidence) in populations is known. Based on 2013-2017 data, about 11.4 per 100,000 persons get this disease every year (114 persons in 1 million population). Males contract more of these cancers.

Use of tobacco (in any form), alcohol use, and infection with human papilloma virus are major causes. However, many persons without any of these risk factors are also known to have developed cancers of the oral cavity or pharynx. Therefore, it is important that everyone in the community remain vigilant about this disease. Fortunately, since oral cancers can be detected simply by clinical examination, patients can screen themselves for any changes in their mouths and can bring these concerns to their dentist or physician for further examination of the oral cavity and pharynx. Majority of the annual 53,000 cases of cancers of the oral cavity and pharynx can be prevented.

What are Oral Potentially Malignant Disorders?

Cancers of the oral cavity are preceded by a stage called oral-potentially-malignant-disorders (OPMD). OPMDs are pre-cancerous lesions that have higher chances of developing oral cancers. OPMD can be observed ten or more years before the cancer develops. OPMD has several forms, but all can be easily seen only by a good clinical examination. Additionally, OPMDs can be cured by themselves, but one needs to be vigilant about persistent OPMDs. A Dentist or Physician will look at the same lesion after 2 to 3 weeks and will determine if the size of the lesion is increasing or decreasing. Further treatment of these lesions can prevent development of oral cancers. The treatment of OPMDs is much less invasive than treatment of cancers. All dentists are trained to detected OPMDs and early cancers. Pre-cancerous stage of cancers of the oral cavity can be detected more than 10 years in advance.

What Can I do to Prevent Oral Cancers?

Some areas in the world have established oral cancer screening programs. Under these programs, all adults are examined periodically for presence of OPMDs or cancers, generally once every three years. Repeated examinations ensure that no one with a tendency to develop OPMD is missed.

The U.S. does not have an oral cancer screening program. But patients can still protect themselves through self-examination, check-ups, and vigilance. Insurance provides for a free dental check up every six months. During your next visit, bring any concerns to your dentist and don’t be afraid to ask for clinical examination and screening for OPMD.

To prevent oral cancers:

  • Conduct a self-examination at least once a month
  • Visit the dentist every six months for routine exams
  • Get yourself screened for oral pre-cancers and cancers
  • Don’t smoke or use any tobacco products and decrease alcohol use
