Oral Cancer – Symptoms, Causes and Preventive Measures

Oral Cancer

Oral cancer, also known as mouth cancer, develops in the oral cavity, which encompasses all visible parts of your mouth when you open wide and look in the mirror. This includes the lips, gums, tongue, cheeks, and the roof or floor of the mouth. Oral cancer occurs when cells on the lips or within the mouth undergo mutations.

Symptoms of Oral Cancer

  • A sore, irritation, or lump in the mouth or on the lips that doesn’t heal
  • Red or white patches on the gums, tongue, tonsils, or lining of the mouth
  • Persistent pain or tenderness in the mouth or lips
  • Difficulty or pain when chewing or swallowing
  • Numbness of the tongue or other areas of the mouth
  • A feeling that something is caught in the throat
  • Chronic bad breath
  • Changes in voice or hoarseness
  • Unexplained weight loss
  • Loose teeth or ill-fitting dentures
  • Swelling in the jaw
  • Ear pain without hearing loss

Early detection of these symptoms can significantly improve the outcome of treatment, so it is important to seek medical advice if any of these signs persist.

Causes of Oral Cancer

The causes of oral cancer can be attributed to various risk factors and behaviors. Some of the primary causes include:

  1. Tobacco Use: Smoking cigarettes, cigars, pipes, or using smokeless tobacco (chewing tobacco, snuff) significantly increases the risk of developing oral cancer.
  2. Excessive Alcohol Consumption: Heavy and regular alcohol use is a major risk factor, especially when combined with tobacco use.
  3. Human Papillomavirus (HPV): Infection with certain strains of HPV, particularly HPV-16, has been linked to an increased risk of oropharyngeal cancers, which affect the base of the tongue, the tonsils, and the walls of the pharynx.
  4. Sun Exposure: Prolonged exposure to sunlight increases the risk of cancer on the lips, especially the lower lip.
  5. Age: The risk of oral cancer increases with age, with most cases occurring in people over 40.
  6. Poor Diet: A diet low in fruits and vegetables may contribute to the development of oral cancer.
  7. Weakened Immune System: Individuals with weakened immune systems, whether due to disease or immunosuppressive medications, have a higher risk of developing oral cancer.
  8. Chronic Irritation: Constant irritation from rough teeth, dentures, or fillings can increase the risk, although this is less common.
  9. Family History: A family history of oral cancer can increase an individual’s risk, although genetic predisposition is less significant compared to lifestyle factors.
  10. Gender: Men are more likely to develop oral cancer than women, partly due to higher rates of tobacco and alcohol use.

By addressing these risk factors through lifestyle changes and preventive measures, the risk of developing oral cancer can be reduced.

Preventive Measures:

Preventive measures for oral cancer focus on reducing risk factors and promoting overall oral health. Here are key strategies to help prevent oral cancer:

  1. Avoid Tobacco Products: Refrain from smoking cigarettes, cigars, pipes, and using smokeless tobacco. Quitting tobacco significantly reduces the risk of oral cancer.
  2. Limit Alcohol Consumption: Reduce alcohol intake, especially avoiding heavy and regular drinking. If you do drink, do so in moderation.
  3. Practice Good Oral Hygiene: Maintain good oral hygiene by brushing and flossing regularly. Visit your dentist for regular check-ups and cleanings.
  4. Protect Yourself from HPV: Consider HPV vaccination, which can protect against HPV strains linked to oral cancers. Practice safe sex and use barrier methods to reduce the risk of HPV infection.
  5. Eat a Healthy Diet: Consume a balanced diet rich in fruits and vegetables. These foods contain vitamins and antioxidants that can help protect against cancer.
  6. Limit Sun Exposure to Lips: Protect your lips from excessive sun exposure by using a lip balm with SPF and wearing a wide-brimmed hat when outdoors.
  7. Avoid Chronic Irritation: Ensure dental appliances, such as dentures or braces, fit properly to avoid constant irritation. Get dental issues like sharp or broken teeth treated promptly.
  8. Reduce Risk Factors for Immunosuppression: If possible, manage conditions that weaken the immune system and avoid unnecessary immunosuppressive medications.
  9. Regular Dental Check-ups: Visit your dentist regularly for examinations. Dentists can detect early signs of oral cancer, such as precancerous lesions.
  10. Stay Informed and Vigilant: Be aware of the symptoms of oral cancer, such as sores, lumps, or white/red patches that don’t heal. Seek medical advice if you notice any persistent changes in your mouth.
  11. Moderate Alcohol and Tobacco Together: Avoid combining tobacco and alcohol use, as the combination significantly increases the risk of oral cancer more than either factor alone.

By incorporating these preventive measures into your lifestyle, you can significantly reduce the risk of developing oral cancer and maintain better overall oral health.
