I've been a dentist in Wyoming for more than 14 years. During that time, I've cared for many patients and spoken to them about the dangers of oral cancer and how their oral health is connected to their overall health. I have seen the devastation that oral cancer can cause. But we can detect and treat oral cancer. Even more importantly, each of us can take steps to try to prevent oral cancer.

Oral cancers often start as a tiny, unnoticed white or red spot or sore anywhere in the mouth. Other signs can include a sore that bleeds easily and does not heal over time, a color change of the oral tissue, a firm lump, pain or numbness anywhere in the mouth, or difficulty chewing and swallowing. However, in the early stages of oral cancer there may not be symptoms.

Tobacco use is not the only risk factor. In fact, excessive alcohol use, poor oral hygiene and ill fitting dentures contribute to the risk of oral cancer. But no life-threatening issue comes up more than the risks associated with tobacco use. It concerns me greatly that the rate of smokeless tobacco use in Wyoming is more then double that of other states in the country.

Oral cancer strikes an estimated 35,000 Americans each year. In 2007, nearly 8,000 people died of these cancers. Only half of all patients diagnosed with oral cancer survive more than five years. In Wyoming we have seen the number of oral cancer cases rise as well as other cancers associated with tobacco use.

Fortunately, we can detect cancerous and pre-cancerous conditions, and the fight against oral cancer can be won. The key is to detect oral cancer early, when the opportunity for a cure is great.

Knowing the risk factors and oral cancer screenings can help prevent this deadly disease. Regular check-ups, including an examination of the entire mouth is essential in the early detection and successful treatment of cancerous and pre-cancerous conditions. But the best way to prevent oral cancer is to avoid tobacco use. Studies also suggest that a diet high in fruits and vegetables may prevent the development of potentially cancerous lesions.

If you have experienced any symptoms of oral cancer or, if you regularly use tobacco products, see your local dentist and ask for a screening test. The test is simple, quick, and it might save your life.
