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.
While sports like football, basketball and soccer have exploded in popularity over the last few decades, many Americans still have a soft spot for the granddaddy of them all: baseball. While technology has changed many aspects of the game, many of its endearing traditions live on.
Unfortunately, one baseball tradition isn’t so endearing and definitely hazardous to health—tobacco, primarily the smokeless variety. Players and coaches alike, even down to the high school level, have promoted or at least tolerated its use.
But there are signs this particular baseball tradition is losing steam. Not long ago, the San Francisco Giants became the first major league baseball team to prohibit tobacco in its home stadium—on the field as well as in the stands. The move was largely in response to a law passed by the City of San Francisco, but it does illustrate a growing trend to discourage tobacco use in baseball.
While smoking, chewing or dipping tobacco can certainly impact a person’s overall health, it can be especially damaging to the teeth, gums and mouth. Our top oral health concern with tobacco is cancer: Research has shown some correlation between tobacco use (especially smokeless) and a higher risk of oral cancer.
You need look no further than the highest ranks of baseball itself to notice a link between tobacco and oral cancer. Although from different eras, Babe Ruth and Tony Gwynn, both avid tobacco users, died from oral cancer. Other players like pitcher Curt Schilling have been diagnosed and treated for oral cancer.
Cancer isn’t the only threat tobacco poses to oral health. The nicotine in tobacco can constrict blood vessels in the mouth; this in turn reduces the normal flow of nutrients and disease-fighting immune cells to the teeth and gums. As a result, tobacco users are much more susceptible to contracting tooth decay and gum disease than non-users, and heal more slowly after treatment.
That’s why it’s important, especially in youth baseball, to discourage tobacco use on the field. While most of baseball’s traditions are worthy of preservation, the chapter on tobacco needs to close.
After her husband, producer Bruce Paltrow, succumbed to oral cancer in 2002, actress Blythe Danner made it her mission to help save other families from the heartache she and her children (Jake and Gwyneth Paltrow) suffered with his loss. Now active with the Oral Cancer Foundation, Blythe uses her fame to bring awareness to the disease, which she says she and her family knew very little about before Bruce received his diagnosis.
In an interview with People magazine, Blythe said she believes her husband's cancer could have been detected earlier if the family had been alert to the symptoms.
“For months I had noticed Bruce's voice was hoarse,” she said. “I started asking him to see a doctor. But he kept saying, ‘No, no, no, I'm fine.’ ”
When a lump became visible in his neck, he did go to the doctor and found he had a tumor in his throat. The cancer eventually spread to his lymph nodes. Compounding Blythe's sadness is the feeling that she might have been able to do something to prevent her husband's death.
“I feel tremendously guilty,” she told the magazine, noting that she wishes she had simply insisted her husband get himself checked out. “Education and early detection are so important,” she said of her campaign to raise awareness. “That's why I'm doing this.”
Though Bruce Paltrow was a smoker, it's important to note that young, non-smokers comprise the fastest-growing segment of the population being diagnosed with the disease. That's because a sexually transmitted virus known as HPV16 is now a major cause of oral cancer.
Oral cancer screenings are yet another good reason to make regular semi-annual visits to the dentist. We have the training to notice oral abnormalities, and to monitor and/or biopsy any suspicious lesions. At your oral cancer screening, we will feel your neck for lumps and inspect your lips and all inside surfaces of the mouth, including the back of your throat.
Of course, if you or a loved one experience persistent hoarseness, white or red patches or other changes in your mouth or tongue that don't go away in a few weeks, please don't hesitate to come in and see us.
