Rock guitarist Eddie Van Halen died last fall after a long battle with oral cancer, another in a long line of performers, athletes, politicians and other well-known personalities with this serious form of cancer. But household names like Van Halen are just the tip of the iceberg: Around 50,000 Americans are diagnosed with oral cancer each year.
Although not as common as other malignancies (around 2.5% of total cancers), oral cancer has one of the lowest five-year survival rates at a dismal 57%. Part of the reason for this has been the longstanding difficulty detecting it in its earlier stages: Early signs are easy to miss or mistake for a benign sore. As a result, it's often diagnosed after advancing significantly, complicating treatment efforts.
To improve survivability, the Oral Cancer Foundation designates each April as Oral Cancer Awareness Month to better educate people on this deadly disease. Here are 3 things you can do to prevent oral cancer or improve your survival odds if you encounter it.
Know your individual risk factors. Some risk factors for oral cancer are out of your control—for example, your risk may be higher if you're a male over 40, or if you're African-American. But there are also factors you can control like tobacco use, high alcohol consumption or a poor diet, all of which can elevate your cancer risk. You can lower that risk by making lifestyle changes for factors you can control and prioritizing cancer screening if you have factors that you can't.
Pay attention to oral “oddities.” A small mouth sore or patch of odd-looking skin may be nothing—or it may be the beginning of oral cancer. If you do notice something unusual, especially if it seems to linger beyond a couple of weeks, have us examine it as soon as possible. If it does appear suspicious, you may need to undergo a biopsy, a cancer analysis of the suspected tissue. If it is cancerous, an early diagnosis could improve your outcome.
Visit your dentist regularly. There's more to semi-annual dental visits than teeth cleaning. Regular dental visits are an important component in your “early warning system” for oral cancer—we may notice something suspicious during your regular visit, often before you do. If you're older or have other risk factors for oral cancer, we can expand your regular exam to include a comprehensive cancer screening.
Oral cancer is a serious matter. But taking steps to prevent it and staying alert to its warning signs can help you overcome it.
Fans everywhere were recently saddened by the news of musical legend Eddie Van Halen's death. Co-founder and lead guitarist for the iconic rock group Van Halen, the 65-year-old superstar passed away from oral cancer.
Van Halen's rise to worldwide fame began in the 1970s with his unique guitar style and energetic performances, but behind the scenes, he struggled with his health. In 2000, he was successfully treated for tongue cancer. He remained cancer-free until 2018 when he was diagnosed with throat cancer to which he succumbed this past October.
Van Halen claimed the metal guitar picks he habitually held in his mouth caused his tongue cancer. It's more likely, though, that his heavy cigarette smoking and alcohol use had more to do with his cancers.
According to the American Cancer Society, most oral cancer patients are smokers and, as in Van Halen's case, are more likely to beat one form of oral cancer only to have another form arise in another part of the mouth. Add in heavy alcohol consumption, and the combined habits can increase the risk of oral cancer a hundredfold.
But there are ways to reduce that risk by making some important lifestyle changes. Here's how:
Quit tobacco. Giving up tobacco, whether smoked or smokeless, vastly lowers your oral cancer risk. It's not easy to kick the habit solo, but a medically supervised cessation program or support group can help.
Limit alcohol. If you drink heavily, consider giving up alcohol or limiting yourself to just one or two drinks a day. As with tobacco, it can be difficult doing it alone, so speak with a health professional for assistance.
Eat healthy. You can reduce your cancer risk by avoiding processed foods with nitrites or other known carcinogens. Instead, eat fresh fruits and vegetables with antioxidants that fight cancer. A healthy diet also boosts your overall dental and bodily health.
Practice hygiene. Keeping teeth and gums healthy also lowers oral cancer risk. Brush and floss daily to remove dental plaque, the bacterial film on teeth most responsible for dental disease. You should also visit us every six months for more thorough dental cleanings and checkups.
One last thing: Because oral cancer is often diagnosed in its advanced stages, be sure you see us if you notice any persistent sores or other abnormalities on your tongue or the inside of your mouth. An earlier diagnosis of oral cancer can vastly improve the long-term prognosis.
Although not as prevalent as other forms of cancer, oral cancer is among the deadliest with only a 60% five-year survival rate. Making these changes toward a healthier lifestyle can help you avoid this serious disease.

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.
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.
