There are a number of lifestyle changes you can make if you want to reduce your risk of oral cancer, with quitting a tobacco habit at the top of the list. You should also moderate your alcohol consumption and practice safe sex to prevent the spread of the human papilloma virus (HPV 16) linked to oral cancer.
And there's one other area that might be ripe for change—your diet. The foods we consume can work both ways in regard to cancer: some, especially processed products with certain chemicals, increase your cancer risk; more natural foods, on the other hand, can help your body fight cancer formation.
Although how cancer forms and grows isn't fully understood, we do know some of the mechanisms involved. One major factor in cancer growth is damage to DNA, the molecule that contains all the instructions for normal cell growth. Certain chemicals called carcinogens cause much of this DNA damage.
One example of these dangerous chemicals are nitrosamines, found in substances used to preserve meats like bacon or ham. Nitrosamines also occur in beer during the brewing process, some fish and fish products, processed cheese and foods pickled with nitrite salt. It's believed long-term consumption of foods with these chemicals can increase the risk of cancer.
On the other hand, there are foods with substances called antioxidants that help our bodies resist cancer. Antioxidants protect cells from unstable molecules called free radicals that can also damage DNA. You'll find antioxidants in abundance in fresh fruits and vegetables, especially those high in fiber. Vitamins like C and E found in many natural foods also have antioxidant properties.
So, to help keep your risk of cancer and other diseases low, make sure your diet includes mostly fresh fruits and vegetables, along with plant-based fats found in nuts or olive oil. At the same time minimize your consumption of processed foods with preservatives and other chemicals, along with animal and saturated fats.
A change in eating not only reduces your cancer risk, it can also improve your overall health and well-being. You'll also find a healthy diet can be dental-friendly—it can help keep your teeth and gums disease-free and healthy.

Each November, the American Cancer Society urges smokers to kick the habit for just one day, because if you can quit for one whole day, you can quit for another whole day. Put enough whole days back to back and you’re no longer a smoker!
According to the U.S. Centers for Disease Control, cigarette smoking is the leading preventable cause of death in the United States. It harms nearly every organ of the body, causing lung disease, heart disease and diabetes, as well as cancer of the lung, kidney and bladder.
Smoking also causes problems in your mouth. Aside from the more obvious problems of bad breath and yellowed teeth, smoking raises the risk of cancer of the mouth and throat. It can increase the buildup of plaque and tartar, which can lead to cavities and gum disease. Smoking interferes with healing, so treatments may not work as well. The majority of smokers have gum disease and they are more likely to lose teeth from advanced gum disease.
Quitting isn’t easy, but it’s the best thing you can do for your health. Who wouldn’t want fresher breath, younger-looking skin and a better sense of taste and smell?
Even for people who have smoked for a long time, the effects of smoking start to reverse themselves when you quit. Your heart rate, blood pressure and carbon monoxide levels in the blood return to normal shortly after quitting. Studies are showing that in just one year, the risk for heart disease is cut in half. 10 years later the risk of oral cancer is about equal to that of a nonsmoker. In 15 years, the risk of heart disease is the same as for a nonsmoker.
Need help quitting? Talk with your dentist or doctor. You can also visit the American Cancer Society website.

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.

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.
A third of people treated for cancer develop adverse side effects within their mouth. But while these effects can be devastating to teeth and gums, there are ways to minimize the damage.
Treatments like chemotherapy and radiation work by destroying cancer cells. Unfortunately, they may also destroy normal cells. The accumulation of this “collateral damage” ultimately affects uninvolved areas and organ systems of the body. Chemotherapy, for example, can interrupt bone marrow blood cell formation and decrease the body's ability to fight infection.
These ripple effects can eventually reach the mouth. It's not uncommon for cancer patients to develop mouth sores or see an increase in tooth decay or periodontal (gum) disease. The treatments may also inhibit saliva flow: because saliva neutralizes acid and provides other benefits that lower disease risk, dental disease is more likely to develop when the salivary flow is reduced.
The first step to minimizing these effects is to improve oral health before cancer treatment begins. An unhealthy mouth vastly increases the chances for problems during treatment. Cooperating with your cancer physicians, we should attempt to treat any diseases present as soon as possible.
During cancer treatment we should also monitor your oral health and intervene when appropriate. If at all possible, you should continue regular dental visits for cleaning and checkups, and more so if conditions warrant. We can also protect your teeth and gums with protective measures like antibacterial mouth rinses, saliva stimulation or high-potency fluoride applications for your enamel.
What's most important, though, is what you can do for yourself to care for your mouth during the treatment period. Be sure to brush daily with a soft-bristle brush and fluoride toothpaste. You can use a weak solution of one-quarter teaspoon each of salt and baking soda to a quart of warm water to rinse your mouth and soothe any sores. And be sure to drink plenty of water to reduce dry mouth.
While you're waging your battle against cancer, stay vigilant about your teeth and gums. Taking care of them will ensure that after you've won your war against this malignant foe your mouth will be healthy too.
