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.

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.
