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.

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.
Your regular dental checkups should periodically include an important screening for oral cancer, especially as you grow older. Although oral cancers make up less than 3% of all other types, they’re among the most deadly with a 58% survival rate after five years.
Besides hereditary factors, oral cancer is strongly linked to tobacco use, alcohol abuse or diets low in fresh fruits and vegetables. It’s also a greater concern as we age: 90% of new cases of oral cancer occur in people over the age of 40, heightening the need for regular screenings. These screenings become all the more important because many early sores or lesions can mimic other conditions like canker sores — without early detection, the disease could already be in advanced stages when it’s diagnosed.
An oral screening for cancer involves both sight and touch. We’ll first look for any suspicious lesions and red or white patches in the soft tissues of the face, neck, lips and mouth. We’ll then feel for any abnormal lumps on the mouth floor, the sides of the neck and in gland locations. We’ll also examine all sides of the tongue including underneath, as well as the tissues lining the back of your throat.
If we notice anything that’s concerning we may then perform a biopsy by removing a small bit of the suspicious tissue and have it examined microscopically for the presence of cancer cells. We may also remove any lesions deemed pre-cancerous as an added precaution against possible cancer development.
The American Cancer Society recommends an oral cancer screening annually for people forty years or older and every three years for people between the ages of 20 and 39. Even better, we recommend all adults undergo a screening every year. This, along with ending tobacco use and other lifestyle and dietary changes, will greatly improve your chances of remaining free of oral cancer.

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.
