NewSalivaTestmayHelpIdentifyOralCancerEarlier

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.

FiveThingsYouShouldKnowAboutOralCancer

Like a shadowy figure hovering at the edge of the movie frame, cancer may be scariest when you can't see it clearly. That's why, instead of looking away, many people have chosen to take a proactive attitude toward the disease. They're learning about the benefits of prevention, early detection and treatment — and so can you. How much do you know about oral cancer? Here are five fast facts.

Oral cancer isn't just an older person's disease.

In the past, people over 40 years of age were the main population group in which oral cancer was found. But in recent years, a growing number of young people have also been diagnosed with the disease. The sexually transmitted Human Papilloma Virus (HPV16) is thought to be responsible for the increase in oral cancer among younger people.

Oral cancer can de deadly.

While it accounts for just 2-3% of all cancers, its survival rate is far lower than lots of cancers you've heard more about. Why? Because its symptoms can be hard to tell from more benign mouth sores, and isn't caught in the early stage often enough. When discovered in its later stages, the 5-year survival rate for this disease is just 58%.

There are several risk factors for oral cancer.

Moderate to heavy drinkers and users of tobacco products — whether smoked or smokeless — are at far greater risk than non-users. Chronic exposure to the sun, besides leading to skin cancer, is also clearly associated with cancers of the lip. And, because of HPV, the same risk factors for other sexually transmitted diseases apply to oral cancer as well. Genetic predisposition also plays a role, as it does in many other diseases.

Lifestyle choices can decrease the odds of getting oral cancer.

Obviously, giving up tobacco, moderating alcohol consumption and avoiding risky sexual behavior will mitigate these risk factors. But you can also lessen your chances of getting the disease by eating a healthy diet. Studies have shown that a high intake of fruits and vegetables is protective against oral cancer — and other cancers as well.

Early detection boosts the survival rate for oral cancer above 80%.

Yet the earliest symptoms of oral cancer are hard for many people to distinguish from common maladies like cold sores. What's the best way to detect it? Do something you should be doing anyway — get regular dental checkups! We're trained to find the signs of a potential problem via a quick, painless screening that can be done at your routine checkup. We can also schedule biopsies or other diagnostic tests if they're needed.
