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.
Although oral cancer isn't the most prevalent among metabolic diseases, it is one of the most deadly with only a 50% survival rate after five years. That's because it can be difficult to detect in its early stages when treatment is most effective.
That's why prevention to reduce your chances of oral cancer is so important. Many people know quitting tobacco products, including smokeless varieties, and moderating alcohol consumption are key to any prevention strategy. But there's one other factor you should also consider: your diet.
We've learned quite a bit in the last few decades about how certain foods we eat contribute to the cancer disease process. Cancer seems to originate when elements in the body or environment (known as carcinogens) damage DNA, our unique genetic code, on the cellular level. For example, a class of chemicals called nitrosamines is a known carcinogen: we often encounter it in the form of nitrites used to preserve meat (like bacon or ham) or as byproducts in beer, seafood or cheese.
Another form of carcinogen is the unstable molecules produced during normal cellular function called free radicals. But our bodies have a natural neutralizer for free radicals called antioxidants. We obtain these substances in our food in the form of vitamins and minerals. While you can also ingest these in the form of supplements, the best way to obtain them is through a diet rich in plant-based food, particularly fruits and vegetables.
So in addition to lifestyle changes like quitting tobacco or moderating alcohol consumption, make sure your diet is a healthy and nutritious one. Limit your intake of processed foods (especially meats) and increase your portions of fresh fruits, vegetables and dairy products.
And don't neglect practicing effective brushing and flossing each day, along with regular dental cleanings and checkups. All of these healthy practices will greatly decrease your chances for life-threatening oral cancer.

Oral cancer is on the rise in the United States, yet few people are familiar with the disease and its risk factors. The National Institute of Dental and Craniofacial Research (NIDCR) estimates that 35,000 Americans are diagnosed with the disease each year. The good news is that prevention and early detection can greatly reduce your risk of developing oral cancer.
Risk Factors for Oral Cancer Include:
- Tobacco: Smoking and using chewing tobacco have been shown to increase the risk of developing oral cancer.
- HPV virus: The Human Papilloma Virus (HPV) is the same virus linked to cervical cancer and genital warts. According to the Oral Cancer Foundation (OCF), many young people and women are being diagnosed with oral cancer as a result of exposure to the HPV virus.
- Age: Although it occurs more frequently in people over the age of 40, the incidence is increasing in younger people.
- Alcohol Consumption: Oral cancer is six times more common in those who drink alcohol excessively.
- Diet: People who consume lots of red and processed meat and fried foods are at greater risk.
Symptoms: Alert our office if you notice a change in your mouth such as a sore that doesn't heal or bleeds easily; a lump, thickening, crust or erosion; pain or tenderness; or a change in the way your teeth are positioned. Our office can administer an easy, painless test that detects abnormal cells.
Other symptoms may include unexplained bleeding or numbness in the mouth, difficulty chewing, swallowing or speaking, hoarseness, chronic sore throat or changes in your voice.
Importance of Dental Screenings: In its early stages, oral cancer can often go unnoticed, but visiting our office regularly can ensure that any cancerous cells are detected and treated early. Our office will check your tongue and the area under your tongue, as well as your lips and palate and the back of your mouth.

Chewing tobacco is as much a part of our sports culture as the national anthem. What once began as an early 20th Century baseball player method for keeping their mouths moist on dusty fields has evolved into a virtual rite of passage for many young athletes.
But the persona of “cool” surrounding smokeless tobacco hides numerous health threats — including disfigurement and death. What isn’t as widely recognized is the degree to which chewing tobacco can adversely affect your teeth, mouth and gums.
Need more reasons to quit? Here are 4 oral health reasons why you should spit out smokeless tobacco for good.
Bad breath and teeth staining. Chewing tobacco is a prime cause of bad breath; it can also stain your teeth, leaving your smile dull and dingy, as well as unattractive from the unsightly bits of tobacco between your teeth. While these may seem like superficial reasons for quitting, a less-than-attractive smile can also have an impact on your self-confidence and adversely affect your social relationships.
The effects of nicotine. Nicotine, the active ingredient in all tobacco, absorbs into your oral tissues and causes a reduction in blood flow to them. This reduced blood flow inhibits the delivery of antibodies to areas of infection in your mouth. This can cause…
Greater susceptibility to dental disease. Tooth decay and gum disease both originate primarily from bacterial plaque that builds up on tooth surfaces (the result of poor oral hygiene). The use of any form of tobacco, but particularly smokeless, dramatically increases your risk of developing these diseases and can make treatment more difficult.
Higher risk of oral cancer. Besides nicotine, scientists have found more than 30 chemicals in tobacco known to cause cancer. While oral cancer constitutes only a small portion of all types of cancer, the occurrence is especially high among smokeless tobacco users. And because oral cancer is difficult to diagnose in its early stages, it has a poor survival rate compared with other cancers — only 58% after five years.
The good news is, you or someone you love can quit this dangerous habit — and we can help. Make an appointment today to learn how to send your chewing tobacco habit to the showers.

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.
