Fans of the legendary rock band Steely Dan received some sad news a few months ago: Co-founder Walter Becker died unexpectedly at the age of 67. The cause of his death was an aggressive form of esophageal cancer. This disease, which is related to oral cancer, may not get as much attention as some others. Yet Becker's name is the latest addition to the list of well-known people whose lives it has cut short—including actor Humphrey Bogart, writer Christopher Hitchens, and TV personality Richard Dawson.
As its name implies, esophageal cancer affects the esophagus: the long, hollow tube that joins the throat to the stomach. Solid and liquid foods taken into the mouth pass through this tube on their way through the digestive system. Worldwide, it is the sixth most common cause of cancer deaths.
Like oral cancer, esophageal cancer generally does not produce obvious symptoms in its early stages. As a result, by the time these diseases are discovered, both types of cancer are most often in their later stages, and often prove difficult to treat successfully. Another similarity is that dentists can play an important role in oral and esophageal cancer detection.
Many people see dentists more often than any other health care professionals—at recommended twice-yearly checkups, for example. During routine examinations, we check the mouth, tongue, neck and throat for possible signs of oral cancer. These may include lumps, swellings, discolorations, and other abnormalities—which, fortunately, are most often harmless. Other symptoms, including persistent coughing or hoarseness, difficulty swallowing, and unexplained weight loss, are common to both oral and esophageal cancer. Chest pain, worsening heartburn or indigestion and gastroesophageal reflux disease (GERD) can also alert us to the possibility of esophageal cancer.
Cancer may be a scary subject—but early detection and treatment can offer many people the best possible outcome. If you have questions about oral or esophageal cancer, call our office or schedule a consultation. You can learn more in the Dear Doctor magazine article “Oral Cancer.”
A half million people are diagnosed every year with oral cancer. While other cancers are more prevalent, oral cancer is among the most dangerous with only a fifty percent five-year survival rate.
A major reason for this low rate is because this fast growing cancer is difficult to detect early — diagnosis comes far too often after the disease has already well advanced. In an effort to detect cancer earlier many dentists visually screen for oral abnormalities during checkups, especially patients over fifty, tobacco or heavy alcohol users, patients with a family history of cancer or a medical history of exposure to the sexually transmitted human papilloma virus, HPV-16.
If they detect an abnormality, the dentist often refers the patient to an oral surgeon or other specialist for a possible biopsy. In this procedure the surgeon removes a sample of the abnormal tissue, which is then examined microscopically for cancer cells. A biopsy remains the most effective way to diagnose oral cancer.
Because of the disease's aggressive nature, many dentists lean to the side of caution when referring patients for biopsy. As a result 90% of oral biopsies reveal no cancer. Reducing the number of biopsy referrals is highly desirable, especially for the patient undergoing the procedure. Tissue samples tend to be large to ensure complete detection of any cancer cells. Depending on the size and location of the sample, there may be a risk for loss of function or disfigurement.
A new screening tool using a sample of a patient's saliva could help reduce the number of biopsy referrals. Besides DNA, saliva also contains dormant genes called biomarkers that activate in response to the presence of a specific disease. This particular saliva test identifies those biomarkers for oral cancer if they're present.
A sample with a low score of biomarkers indicates no cancer present (with a statistical confidence of 99%). A medium or high score indicates cancer may be present, but only a biopsy can determine for sure. Using this test, dentists might be able to reduce the number of biopsy referrals and instead be able to employ watchful waiting in certain cases. Because of its simplicity and non-invasiveness, saliva screening could help identify oral cancer earlier.
For years, even as tobacco use began to decline and disappear in most settings, professional baseball seemed one of the few exceptions. Now, the tide is finally turning. Recently, the legendary right-hand pitcher Curt Schilling revealed that he had been treated for oral cancer — and said that his chewing tobacco habit was to blame. “I’ll go to my grave believing that was why I got [cancer],” Schilling told the Boston Globe.
Schilling isn’t the only former player whose oral cancer is blamed on smokeless tobacco. Tony Gwynn, Hall of Famer and beloved coach, recently passed away from oral cancer at the age of 54. His death led to players pledging to give up the habit. But many still use “dip” or “snuff,” thinking perhaps it’s not so bad after all.
In fact, nothing could be further from the truth. With nicotine as its active ingredient, chewing tobacco can be just as addictive as cigarettes. Not only is nicotine addictive, it also increases heart rate and blood pressure, constricts the arteries, and affects the body in other ways. In addition to nicotine, chewing tobacco contains about 30 other chemicals known to cause cancer.
Tobacco use of any kind is a major risk factor for oral cancer. While it isn’t as well-known as some other types of cancer, oral cancer can be just as deadly. About 43,000 people in the U.S. are diagnosed with it each year — and the 5-year survival rate is just 57%. One reason for the relatively low survival rate is that oral cancer isn’t usually detected until it has reached a later stage, when it’s much harder to treat.
What can you do to reduce your risk for oral cancer? Clearly, you should stop using tobacco products of any kind. Moderating your intake of alcohol, and eating more plant foods and less red meat can also have an impact. And don’t forget to have regular dental checkups: cancer’s warning signs can often be recognized in an oral examination — and early detection can boost survival rates to 80-90 percent.
How does Schilling feel about chewing tobacco now? “I lost my sense of smell, my taste buds for the most part. I had gum issues, they bled, all this other stuff,” he told the Globe. “I wish I could go back and never have dipped. Not once.”

Actor Michael Douglas shocked TV audiences across the country when he announced on the David Letterman Show in 2010 that he has stage IV oral cancer. Fortunately, the cancer had not spread and his radiation and chemotherapy treatments were successful. This year, Douglas teamed up with the Oral Cancer Foundation to warn others about the dangers of the disease and the importance of early detection. In particular, he wants younger people to know that even if they don't smoke and drink a lot, as he admitted to Letterman that he did, they are still at risk.
As Douglas states in a PSA he made with the foundation, “the fastest growing segment of the people developing oral cancers are young, non smokers.” That's due to a strain of the Human Papilloma Virus known as HPV16 that can be transmitted through oral sex. So it's important to avoid risky sexual behaviors and to be screened regularly for this devastating disease that claims one life every hour in the U.S., according to the Oral Cancer Foundation.
An oral cancer screening is a simple visual and tactile exam done right here at the dental office. We will feel your neck for lumps and inspect your lips and all inside surfaces of the mouth, including the back of your throat, for any suspicious signs. If any are found, a biopsy (laboratory analysis of a tissue sample) can be ordered.
Most oral cancers are “squamous” (small scale-shaped) cell carcinomas that occur in the lining of the mouth and are often preceded by recognizable changes (lesions) of the oral membranes. White or red patches begin to form in the pre-cancerous stage, and as the cancer develops, a non-healing ulcer may appear. If you notice any such changes in your mouth, please let us know.
Michael Douglas ends his PSA with the following plea: “So please, the next time you visit your dentist or your medical doctor, ask for this simple screening. Finding oral cancer in its earliest stages may save your life.” We agree, which is why we always perform this screening during your regular dental check-up. If it's been a while since your last appointment, please come in and see us.
