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.

Oral cancer screenings can save your smile and your life! The incidence of this quickly spreading cancer increases every year in the United States, says the Oral Cancer Foundation, but through early detection, cure rates can increase. Your Danbury, CT, dentist, Dr. George Landress, screens his older teen and adults patients for this harmful malady as part of routine exams and cleanings.
Fast, easy, and effective
That describes oral cancer screenings with Dr. Landress. They take just a few minutes. First, your dentist will look into your mouth, inspecting the tongue and under the tongue, the roof of your mouth, inside the cheeks, at the back of the throat, and more. He'll palpate, or feel, the sides of your throat and then that's it. You're done.
Signs and symptoms of oral cancer
What is Dr. Landress looking for? Frankly, he looks for things that may not be noticeable to you. In reality, they may indicate the squamous cell carcinoma that comprises most cancerous lesions at the back of the throat, on the tongue and lips and on the salivary glands. These lesions may be white or red in color and do not heal quickly as a cold sore does.
Additionally, patients with oral cancer often have:
- Pain when eating
- Difficulty swallowing
- A change in the fit of a denture or in dental bite
Its origin and how to avoid it
The Oral Cancer Foundation cites many causes for this kind of cancer. They include:
- Too much sun exposure
- Alcohol abuse
- Chewing tobacco
- Exposure to HPV, the Human Papilloma Virus (which is sexually transmitted)
While oral cancer seems to cross age, gender, and racial lines, men suffer from it more than women do. However, the National Cancer Institute indicates that incidence among young women has risen sharply over the past few years.
Because of the deadly results of this cancer, Dr. Landress urges his patients to live a healthy lifestyle. A diet high in fibrous fruits and vegetables seems to help. Stop all tobacco use, and limit your sun exposure, particularly deliberate tanning. Look into your mouth and at your lips regularly, and see your dentist in Danbury every six months for your routine screening.
It's your life
Preserve it with easy oral cancer screening. Please call Dr. George Landress in Danbury, CT, today to arrange your six-month cleaning and check-up, and get some peace of mind at (203) 743-7608.
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.
Good nutrition is vital for maintaining health and preventing disease, especially for your mouth. A diet rich in whole foods — fresh fruits and vegetables, protein and dairy products — and low in sugar will not only promote strong teeth and gums, but lessen your chances of developing tooth decay or periodontal (gum) disease.
Diet is also a prominent factor in reducing the risk for another serious mouth disease — oral cancer. While oral cancer makes up only 3% of total cancer cases reported annually, the five-year survival rate is a sobering 50%, much lower than for other types of common cancers. While genetics plays a role in your susceptibility to oral cancer, lifestyle choices and practices present the greater risk factors for the disease.
Of these lifestyle factors, refraining from tobacco products, moderating your alcohol consumption and avoiding risky sexual behavior are of primary importance in reducing your cancer risk. With that said, you should also take into account the foods that are part of your daily diet — both what you should and shouldn’t eat. As an example of the latter, some foods contain a class of chemicals known as nitrosamines that are carcinogenic (cancer-causing). One such chemical, nitrite, is used as a preservative in meats like bacon or ham, and may also be found in beer, and seafood products.
On the positive side, your diet should be rich in foods that supply antioxidants, substances that protect the body’s cells from damaging, unstable molecules known as free radicals. The best sources for antioxidants (more so than dietary supplements) are plant foods rich in fiber and vitamins C and E. Eating more of these may also reduce your intake of nitrates, animal fat and saturated fat.
Adopting a moderate, nutritious diet, along with exercise, can have a huge positive impact on your general health and quality of life. Along with other lifestyle changes, better dietary choices can also help ensure a healthy mouth and reduce your risk of oral cancer.

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.
