Mouth Cancer

Mouth cancer, also known as oral cancer, involves the development of malignant cells in any part of the mouth, including the lips, tongue, cheeks, floor of the mouth, hard and soft palate, sinuses, and pharynx (throat). Early detection is crucial as it significantly increases the likelihood of successful treatment and survival.                         

Types of Mouth Cancer

Mouth cancer is typically classified based on the area of the mouth where it originates:    

• Lip Cancer:
  
  • Usually occurs on the outer lips and is often associated with excessive exposure to sunlight.
• Tongue Cancer:
  
  • Affects either the front of the tongue (oral tongue) or the base where it connects to the throat (base of the tongue).
• Cheek Cancer (Buccal Mucosa Cancer):
  
  • Cancer that starts in the inner linings of the cheeks.
• Floor of Mouth Cancer:
  
  • Develops in the area under the tongue.
• Hard and Soft Palate Cancer:
  
  • Occurs in the roof of the mouth.
• Gum Cancer:
  
  • Begins in the gums around the teeth.

Symptoms of Mouth Cancer

Common signs and symptoms of mouth cancer may include:

• A sore or ulcer in the mouth that does not heal
• Red or white patches in the mouth
• Persistent pain in the mouth
• A lump or thickening in the cheek
• A sore throat or feeling that something is caught in the throat
• Difficulty chewing or swallowing
• Jaw stiffness or pain
• Numbness of the tongue or other parts of the mouth
• Swelling of the jaw that causes dentures to fit poorly or become uncomfortable
• Unexplained weight loss

Risk Factors - Mouth Cancer

Key risk factors for developing mouth cancer include:

• Tobacco Use:
  
  • Smoking cigarettes, cigars, pipes, or using chewing tobacco increases the risk.
• Alcohol Consumption:
  
  • Heavy alcohol use is another significant risk factor, especially when combined with tobacco.
• Human Papillomavirus (HPV) 
  
  • Certain HPV strains are linked to mouth and throat cancers.
• Excessive Sun Exposure:
  
  • Especially relevant for lip cancer.
• Poor Diet:
  
  • A diet low in fruits and vegetables may increase the risk..
• Age
  
  • Risk increases with age, particularly for people over 40.

Diagnosis

The diagnosis of mouth cancer generally involves:

• Examination:
  
  • A thorough examination of the lips and mouth to look for areas of irritation, sores, and white patches.
• Biopsy:
  
  • Removing a tissue sample for testing to determine the presence of malignant cells.
• Imaging Tests:
  
  • Such as X-rays, CT scans, MRIs, or PET scans to determine the extent of cancer and if it has spread.

Treatment Options

Treatment for mouth cancer depends on the cancer's location, stage, and the patient's overall health:

• Surgery:
  
  • To remove the tumor and some of the healthy tissue around it, and possibly lymph nodes in the neck.
• Radiation Therapy:
  
  • Often used for early-stage cancers or in combination with surgery.
• Chemotherapy:
  
  • Used in conjunction with radiation therapy for more advanced stages or for cancers that have spread.
• Targeted Therapy: 
  
  • Drugs that specifically target cancer cell abnormalities.
• Reconstructive Surgery 
  
  • To rebuild the mouth's structure and appearance following cancer removal.

Mouth cancer can be particularly challenging due to its impact on essential functions such as eating, speaking, and swallowing. Preventive measures like avoiding tobacco and excessive alcohol, protecting lips from the sun, maintaining oral hygiene, and regular dental check-ups are crucial for early detection and prevention. In the UK, comprehensive resources and support systems are available to assist individuals diagnosed with this disease, improving outcomes and providing necessary care throughout their treatment journey.
