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.
If you’ve noticed a small sore in your mouth, it’s possible you have a non-contagious disease known as lichen planus. Although usually benign, it’s still a good idea to have it examined and monitored.
The condition is so named because its lesions are similar in appearance to lichen, the algae and fungi organism often found on rocks and trees. It’s believed to be a type of autoimmune disease, in which the body treats some of its own cells as foreign and reacts adversely to them. Certain medications and substances may also cause a lichenoid reaction. Besides the inner cheeks, gums or tongue, lichen planus may also appear on other skin or mucous surfaces on the wrists, legs or fingernails.
When it appears inside the mouth it usually resembles a lacy pattern of white lines or ulceration. Gum tissues may become red and inflamed, with some soreness after brushing or eating. Although there’s no known cure for lichen planus, it rarely causes serious problems — in fact, you may not even be aware you have the condition unless pointed out during a dental exam. It may, in time, fade away.
If the lesions do become bothersome (painful, itchy or overly-sensitive), there are some ways to ease discomfort: brushing with a soft toothbrush (to minimize irritation), flossing, and avoiding acidic or spicy foods and beverages which have been known to cause flare-ups. Managing stress is also helpful, and a topical steroid may be prescribed for more severe outbreaks.
Perhaps the greatest concern with lichen planus, though, is it may resemble more serious conditions, particularly oral cancer. The only way to be certain that it is a benign condition is to perform a biopsy on some of the affected tissue. If you notice a problem, be sure to visit us for a complete examination. And regardless of whether you have the condition or not, regular oral cancer screenings, as well as limits on alcohol consumption and stopping use of tobacco, will also reduce your risk of oral cancer.
Odds are if you have a case of lichen planus it isn’t causing you any problems. If it does cause you discomfort, though, you can take steps to ease your symptoms.
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.”
