This month marks the 20th annual observance of Oral Cancer Awareness Month. Last year, over 50,000 people in the US were diagnosed with oral cancer, and over 10,000 people died from the disease. The 5-year survival rate for oral cancer is only around 57%, making it more deadly than many other types of cancer. But if oral cancer is caught and treated early, the 5-year survival rate jumps to over 80%. This is one reason why regular dental checkups are so important—we can be your best ally in detecting oral cancer in its early stages.
Oral cancer is particularly dangerous because it often develops without pain or obvious symptoms. Early detection greatly improves the chances of successful treatment, but signs of the disease frequently go unnoticed until the cancer is advanced. Fortunately, dentists and dental hygienists are trained to recognize signs of oral cancer in the early stages, when it is most treatable. Oral cancer can appear on any surface of the mouth and throat, with the tongue being the most common site, particularly along the sides, followed by the floor of the mouth. As part of a regular dental exam, we examine these surfaces for even subtle signs of the disease.
Screenings performed at the dental office are the best way to detect oral cancer, but between dental visits it's a good idea to check your own mouth for any of the following: white or red patches, lumps, hard spots, spots that bleed easily or sores that don't heal. Let us know if any of these symptoms don't go away on their own within two or three weeks.
Using tobacco in any form is a major risk factor for oral cancer, especially in combination with alcohol consumption. Although the majority of people diagnosed with oral cancer are over age 55, the fastest growing segment of new diagnoses are among young people due to the rise in cases of sexually transmitted human papillomavirus (HPV) in young adults.
A routine dental visit can do much more than preventing and treating tooth decay and gum disease—it might even save your life! If you have questions about oral cancer or are concerned about possible symptoms, call us as soon as possible to schedule an appointment for a consultation.
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.
