Understanding the Risk Factors for Oral Cancer

Oral cancer might not be something you think about very often, but it’s more common than you’d expect. Every year, thousands of people in the U.S. are diagnosed with oral cancer. While this disease is often deadly, an early diagnosis can make all the difference. 

But what puts someone at risk for oral cancer? While anyone can develop it, certain habits and health conditions can increase your chances. Understanding the risk factors for oral cancer is the first step in preventing this disease. From adjusting your diet to quitting smoking, a few small changes can make a big difference. Here’s what you need to know. 

Five Common Risk Factors for Oral Cancer

1: Alcohol & Tobacco Use

Smoking, vaping, chewing tobacco, and excessive alcohol consumption are some of the biggest risk factors for oral cancer. These substances expose your mouth to harmful chemicals that damage the cells over time.

Using nicotine and alcohol together increases your risk even more. Alcohol dries out the tissues in your mouth, making them more vulnerable to the cancer-causing chemicals in tobacco products. If you drink and smoke, your chances of developing oral cancer are significantly higher.

2: Poor Nutrition & Oral Health

A diet lacking in fresh fruits and vegetables can leave your body without the vitamins and antioxidants it needs to fight cell damage. Without these essential nutrients, your immune system may also be weaker, making it harder for your body to stay healthy.

Additionally, poor oral hygiene can contribute to chronic inflammation in the mouth, which may make it easier for abnormal cells to develop. Skipping your regular dental visits, neglecting to brush and floss, or ignoring persistent issues like canker sores or gum infections can all add to your risk.

3: Human Papillomavirus (HPV) 

HPV is one of the most common viruses in the world, and certain strains are directly linked to throat and oral cancers. Although it spreads through skin-to-skin contact, many people don’t realize they have it, because it doesn’t always cause symptoms. 

Just like bacteria in the mouth can cause illness in other parts of your body, viral infections like HPV can cause abnormal cell growth that leads to cancer. The good news? Vaccines are available that help protect you against high-risk strains of HPV.

4: Age & Genetics

While oral cancer can occur at any age, it’s most commonly diagnosed in people over 40. That’s because repeated exposure to risk factors like tobacco, alcohol, or UV rays can increase the likelihood of abnormal cell growth.

Family history can also play a role. If a close relative has had oral cancer, you may have a higher risk of developing it due to inherited genetic factors. While you can’t change your genetics, being aware of your family history should encourage you to take preventive steps early on.

5: Sun Exposure

Lip cancer is one of the most preventable forms of oral cancer, yet it still occurs quite frequently—especially in people who spend a lot of time outdoors. The skin on your lips is thinner and more sensitive than the rest of your face, making it more vulnerable to UV damage.

People who work outside, frequently use tanning beds, or live in sunny climates should be especially cautious. One simple way to protect yourself is by using a lip balm with SPF. You can also wear a wide-brimmed hat when spending extended time in the sun.
