Mouth Cancer: Causes, Symptoms, and Risk Factors

Cancer is a disease that can affect any part of the body, and the mouth is no exception. Mouth cancer, also known as oral cancer, refers to cancer that develops in any of the parts that make up the mouth. It can occur on the lips, tongue, gums, the inner lining of the cheeks, the roof of the mouth, and the floor of the mouth under the tongue. Mouth cancer is a serious medical condition that requires early detection and treatment.


What Causes Mouth Cancer?

Like many forms of cancer, the exact cause of mouth cancer is not always clear, but several contributing factors increase the risk of developing the disease. These include:

Tobacco Use

Tobacco, in all its forms—cigarettes, cigars, pipes, and chewing tobacco—is a significant risk factor for mouth cancer. Chemicals in tobacco can damage the cells in your mouth, leading to cancer over time.

Alcohol Consumption

Excessive alcohol consumption is another major risk factor. Alcohol can erode the lining of the mouth, making it more susceptible to cancer. The risk is even higher for those who both smoke and drink.

HPV Infection

The human papillomavirus (HPV), particularly HPV type 16, is linked to a subset of oral cancers. It is the same virus that can cause cervical cancer in women.

Excessive Sun Exposure

Excessive exposure to sunlight can increase the risk of cancer on the lips, especially the lower lip.

Poor Nutrition

A diet low in fruits and vegetables may increase the risk of mouth cancer.

Symptoms of Mouth Cancer

Mouth cancer can present a variety of symptoms, including:

  • A sore that doesn't heal
  • A lump or thickening in the cheek
  • A white or red patch on the gums, tongue, tonsil, or lining of the mouth
  • Jaw pain or stiffness
  • Difficulty chewing or swallowing
  • A feeling that something is caught in the throat
  • Numbness in the tongue or other areas of the mouth
  • Swelling of the jaw

It's important to note that these symptoms could be indicative of other non-cancerous conditions, so it's best to consult a healthcare provider for an accurate diagnosis.

Risk Factors for Mouth Cancer

Several factors may increase the risk of developing mouth cancer, including:

Age: Mouth cancer is more common in people over 40.

Gender: Men are twice as likely as women to develop mouth cancer.

Family History: A family history of cancer could increase the risk.

Poor Oral Hygiene: Not taking care of your teeth and gums can lead to an increased risk of mouth cancer.

Weak Immune System: People with weakened immune systems are more susceptible.

Reducing the Risk of Mouth Cancer

There are steps you can take to reduce your risk of developing mouth cancer, such as:

  • Quitting tobacco in all forms
  • Limiting alcohol consumption
  • Eating a diet rich in fruits and vegetables
  • Protecting your lips from the sun with a lip balm that contains sunscreen
  • Regular dental check-ups that include an examination of the entire mouth

Mouth cancer, like all cancers, can be life-threatening, but it's also preventable and treatable, especially when caught early. Being aware of the symptoms and risk factors is the first step in prevention. If you experience any warning signs or are at high risk, contact your healthcare provider promptly for an evaluation.
