An estimated 50,000 Americans are expected to be diagnosed this year with some form of oral cancer. Five years from now, if current survival rates still apply (57%), a little more than half will still be alive. That's why the Oral Cancer Foundation designates each April as Oral Cancer Awareness Month to call attention to this serious disease, and what you can do to lower your risk of contracting it.
Oral cancer has one of the lowest survival rates among known cancers, mainly because it easily goes undetected until its later stages when known treatments aren't as effective. Patients don't always have overt symptoms or they mistake cancerous lesions for everyday mouth sores. On the other hand, early detection and treatment dramatically improve survivability.
Here are some things you can do to reduce your risk for oral cancer or improve your odds for early detection.
Don't use tobacco. If you're a smoker, you're five to nine times more likely to develop oral cancer than a non-smoker. Using smokeless snuff or chewing tobacco is also risky—four times the risk of non-users. And preliminary evidence suggests that e-cigarettes increase the risk of cancer as well.
Make better food choices. A diet heavy in processed foods, especially nitrites used in curing meats and other products, can damage cellular DNA and lead to cancer. On the other hand, natural foods like fresh fruits and vegetables contain nutrients that lower cancer risk. A nutritious diet also contributes to healthier teeth and gums.
Practice safer sex. While older adults have traditionally accounted for most oral cancer cases, there has been a recent, unsettling rise among younger people. Most researchers tie this to the Human Papilloma Virus (HPV 16), which is sexually transmitted. You can reduce your risk for contracting HPV 16 and subsequent oral cancer by following safe sex practices.
Undergo oral cancer screenings. Your semi-annual dental visits to clean your teeth are also a prime opportunity to check for oral abnormalities, especially if you're older. During an oral cancer screening we visually inspect your face, neck, lips and the inside of your mouth for any suspicious sores or discolorations. Early detection leads to better outcomes.
You should also modify your alcohol consumption—moderate to heavy drinkers have three to nine times greater risk for oral cancer than light or non-drinkers. And, you can further lower your risk of lip cancers by limiting your exposure to the sun and wearing protective sunscreen.
Oral cancer is a dangerous condition that could threaten your life. Regular dental care and healthy lifestyle practices can help lower your risk for encountering this deadly disease.
Chewing tobacco, especially among young athletes, is considered fashionable — the “cool” thing to do. Many erroneously think it’s a safe alternative to smoke tobacco — it is, in fact, the source of numerous health problems that could ultimately lead to disfigurement or even death.
Chewing or dipping tobacco is especially linked with the sport of baseball. Its traditions in baseball go back to the late Nineteenth Century when players chewed to keep their mouths moist on dusty fields. The habit hit its greatest stride after the surgeon general’s warning on cigarettes in the late 1950s. Now, players wishing to emulate their major league heroes are prone to take up chewing tobacco at an early age.
But the habit comes with a price tag. Individuals who chew tobacco are more susceptible to oral problems like bad breath, mouth dryness, or tooth decay and gum disease. Users also increase their risk for sexual dysfunction, cardiopulmonary disease (including heart attack and stroke) and, most notably, oral cancer.
Derived from the same plant, chewing and smoke tobacco share a common trait — they both contain the highly addictive drug nicotine. Either type of user becomes addictive to the nicotine in the tobacco; and like smoking, a chewing habit can be very difficult to stop.
Fortunately, many of the same treatments and techniques for quitting smoking can also be useful to break a chewing habit. Nicotine replacement treatments like Zyban or Chantix have been shown effective with tobacco chewing habits. Substituting the activity with gum chewing (non-nicotine, and with the sweetener Xylitol), or even an herbal dip can also be helpful.
Like other difficult processes, it’s best not to try to quit on your own. You should begin your efforts to quit with a consultation with your doctor or dentist — they will be able to prescribe cessation medications and provide other suggestions for quitting. You may also find it helpful to visit a behavioral health counselor or attend a tobacco cessation support group.
Rather than just one approach, successful quitting usually works best with a combination of techniques or treatments, and perhaps a little trial and error. The important thing is not to give up: the improvements to your dental health — and life — are worth it.

Oral cancer is not as uncommon as people think. In 2008 an estimated 34,000 cancers of the mouth and throat were diagnosed. In order to minimize your risk of developing oral cancer, be aware of habits that increase your risk.
Risk Factors for Oral Cancer include:
- Use of smoking or chewing tobacco: Tobacco smokers have 5-9 times greater risk of developing this cancer than non-users; snuff and chewing tobacco users have a four times greater risk than non-users.
- Excessive use of alcohol: Moderate to heavy drinkers at are 3-9 times greater risk than non-drinkers.
- Exposure to sun: Chronic sun exposure is associated with development of lip cancers.
- Certain viral infections such as the human papilloma virus that can cause cervical cancer in women can also cause oral cancer.
- Compromised immune (resistance) systems that are not functioning properly can be associated with cancers.
- Poor nutrition including diets low in fruits and vegetables can increase risk for all cancers including oral cancer.
- Family history: People carry a predisposition in their DNA (the genetic material they inherited from their parents) for developing cancer.
Oral Cancers Can Mimic Harmless Sores
Early signs of oral cancer can mimic harmless sores that occur in the mouth such as canker sores, minor infections, or irritations that occur from biting or eating certain foods. Cancers in the lip area can easily be mistaken for harmless sores.
Early Detection is Key
It is important to have regular oral examinations to detect signs of oral cancer. Although 90 percent of oral cancers occur in people who are over 40, it is becoming more prevalent in younger people, particularly those who adopt risky behaviors: smoking, drinking and oral sex.
- If you notice any unusual lesions (sores or ulcers), or color changes (white or red patches), anywhere in your mouth that do not heal within two to three weeks, come and see us and have it examined immediately.
- Definitive diagnosis may require a small biopsy, the microscopic examination of a piece of tissue from the affected area.
It is important not to let a suspicious sore go unchecked. If detected and treated early, while a lesion or growth is small, survival rates can exceed 80 percent.

While genetics certainly plays a role in a person's susceptibility to various forms of cancer (including oral cancer), there are lifestyle factors that also play a role.
In the case of developing oral cancer, there are a number of prominent lifestyle changes you can make to help reduce your risk: protect yourself from too much sun exposure; avoid the use of any type of tobacco (smoke and smokeless); limit your intake of alcoholic beverages to a moderate level; abstain from risky sexual behavior; and eat a diet rich in fresh fruit and vegetables, as well as other whole foods.
That last lifestyle change not only reduces your level of negative exposure from the environment, it may also provide a positive effect as well. For example, normal cellular function produces unstable molecules known as “free radicals” that can damage the DNA structure within the cell; this could be a precursor to the development of cancer. There are natural substances, however, that can help protect cells against the damage caused by free radicals. These are known as “antioxidants” and they are abundant in many plant-based foods. You, of course, may know them by other names: vitamins, carotenoids (found in red and orange fruits and vegetables) or fiber, to name a few.
A well-balanced diet can provide these and other kinds of cancer-fighting nutrients. And, it's important that you eat the source of these nutrients — fresh plant-based foods. Studies have shown that dietary supplements can't match the effectiveness of actually eating fruit and vegetables.
Besides lowering your cancer risk, a plant-based, whole food diet will also result in better oral health. Diets heavy in processed foods with high amounts of sugar or other bacteria-friendly substances inhibit good oral health.

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.
