Oral Cancer Risk Factors: What Increases the Risk of Oral Cancer?

Oral cancer may not be as well-known as other types of cancer, but it's still a serious disease that can lead to life-threatening consequences. 

Unfortunately, many people are unaware of the risk factors that increase their chances of developing oral cancer. 

In this blog post, we'll explore some of the key risk factors associated with this debilitating condition and provide practical tips on reducing your risks and protecting yourself from oral cancer. So, buckle up for an informative journey into oral cancer risk factors!

What Is Oral Cancer?

Oral cancer is a type of cancer that affects the tissues in the mouth and throat. It can occur in any part of the mouth, including the lips, gums, tongue, or floor of the mouth. 

Oral cancer is most often diagnosed in people over the age of 40, and the risk of developing oral cancer increases with age. Other risk factors for oral cancer include smoking, heavy alcohol use, and betel nut chewing. 

If you suspect you may have oral cancer, it is important to see a doctor or dentist right away. Early detection and treatment are key to improving the chance of successful treatment. 

​Symptoms of oral cancer can include pain in the mouth and neck, a lump in your neck, a sore that does not heal, difficulty swallowing or chewing, and numbness in your jaw or tongue.

Oral Cancer Causes & Risk Factors

It is estimated that about 43,000 Americans will be diagnosed with oral or oropharyngeal cancer this year. 

Though the incidence of oral cancer has been declining over the past few decades due in part to less use of tobacco products, it is still relatively common. 

Several risk factors can increase the chance of developing oral cancer.

1. Tobacco Use: 

Cigarette smoking is the most important risk factor for oral cancer. Pipe smokers and cigar smokers also have an increased risk, though not as great as cigarette smokers. 

Smoky tobacco products such as chewing tobacco and snuff also increase the risk of oral cancer.

2. Alcohol Use: 

Heavy drinkers are at increased risk for developing oral cancer, especially if they also smoke cigarettes.

3. Betel Nut Use: 

A betel nut is a seed that is chewed with other ingredients wrapped in a leaf from the betel pepper plant. 

This practice is common in South Asia and some Pacific Island cultures. Chewing betel nuts can increase the risk of developing oral cancer.

4. HPV Infection: 

HPV is a virus that has been linked with several types of cancers, including cervical and anal cancer. 

Some strains of HPV are also associated with an increased risk of oropharyngeal cancer, which includes cancers of the back of the throat, the base of the tongue, and the tonsils.

5. Poor Nutrition: 

A diet low in vitamins and minerals may increase the risk of developing oral cancer. Eating a diet high in fruits and vegetables has been linked with a decreased risk of oral cancer.

6. Age: 

The risk of developing oral cancer increases with age. Most oral cancers develop in people over the age of 40, though the incidence is rising among younger adults, likely due to HPV infection. 

7. UV Exposure: 

Exposure to UV radiation from the sun or tanning beds can increase the risk of mouth and throat cancers.

8. Weakened Immune System: 

People with weakened immune systems due to HIV, AIDS, or other conditions may have an increased risk of oral cancer.

9. Exposure to Certain Chemicals: 

Working with or being exposed to asbestos and other toxic fumes increases the risk of oral cancer.

10. Family History: 

Having one or more family members with oral cancer may increase the risk of developing it. 

11. Excessive Sun Exposure: 

Prolonged exposure to UV radiation from the sun can damage cells and increase the risk of skin cancer, including lip and mouth cancer. 

Wearing sunscreen and protective clothing can help minimize this risk.

Risk of Oral Cancer After Quitting Smoking

It's no secret that the risk of oral cancer is quite high thanks to unhealthy habits and lifestyles like smoking is one of the most significant risk factors for developing oral cancer. 

In fact, according to the Oral Cancer Foundation, smokers are six times more likely to develop oral cancer than nonsmokers. 

But what many people don't realize is that the risk of developing oral cancer decreases significantly after quitting smoking.

According to a study published in the journal Cancer Epidemiology, Biomarkers & Prevention, people who quit smoking have a 50% lower risk of developing oral cancer than those who continue to smoke. 

This decrease in risk is seen within just five years of quitting smoking. So if you're a smoker and looking to reduce your risk of oral cancer, quitting is one of the best things you can do.

Risk of Oral Cancer After Quitting Chewing Tobacco

The risk of oral cancer after quitting chewing tobacco is very low. Studies have shown that the risk of oral cancer for ex-smokers is no different than the risk for people who have never smoked. 

However, it is still important to see your dentist regularly and to report any changes in your mouth, such as new or worsening symptoms, to your dentist right away. 

It is important to also remember that quitting chewing tobacco does not guarantee a lower risk of developing oral cancer. While the risk may be lower, people who have never chewed tobacco are still at risk. 

Oral hygiene and diet can play a role in preventing oral cancer. 

• Limiting alcohol consumption, 
• Avoiding smoking 
• Exposure to Ultraviolet (UV) rays, 
• Eating a balanced diet that includes fruits and vegetables, 
• Maintaining good dental hygiene is an important factor in reducing the chances of developing oral cancer or its recurrence.

Oral Dysplasia And Risk Of Progression To Cancer

Oral dysplasia is a precancerous condition that refers to the abnormal growth of cells in the mouth. 

While most cases of oral dysplasia do not progress to cancer, there is a small risk that it could develop into oral cancer if left untreated. 

Several factors can increase the risk of Oral Dysplasia And The Risk Of Progression To Cancer.

But of them all, there are 3 major reasons why people suffer from Oral Cancer such as:

1. Tobacco Use: 

Tobacco use, whether it’s smoking or chewing, is the leading cause of oral cancer. People who use tobacco products have a much higher risk of developing oral cancer than those who don’t.

2. Alcohol Use: 

Heavy alcohol use is also a major risk factor for oral cancer. The more alcohol you drink, the greater your risk becomes.

3. HPV Infection: 

Certain types of HPV (human papillomavirus) can increase the risk of developing oral cancer. 

HPV is transmitted through sexual contact and is more common in people who have multiple sexual partners.

If you have any of these risk factors, it’s important to be aware of the signs and symptoms of oral cancer so you can catch it early. 

Some common signs include sores or lumps in the mouth, pain or difficulty swallowing, changes in voice or hoarseness, and unexplained bleeding in the mouth. 

If you notice any of these symptoms, make an appointment with your dentist or doctor immediately for an evaluation.

• HPV infection is another risk factor for oral cancer. HPV is a group of viruses that can cause infections in the mouth and throat. 
• In some people, HPV infection can lead to the development of cancerous tumours. It is estimated that more than 50% of oral cancers in India are linked to HPV infection. 
• Despite these risk factors, the vast majority of people who use tobacco products, chew betel quids, drink alcohol, or are infected with HPV will never develop oral cancer. 
• However, it is estimated that over 400,000 Indians suffer from oral cancer each year.
