Buccal Mucosa Cancer

The buccal mucosa is the lining of the cheeks and the back of the lips, inside the mouth where they touch the teeth.

Symptoms

Symptoms include:

  • No symptoms in the early stage
  • White or red lump in the mouth that does not go away after two weeks
  • A red, raised patch in the mouth that bleeds easily
  • A lump or thickening in the mouth
  • Pain increases when eating or drinking
  • Soreness or a feeling that something is caught in the throat
  • Difficulty chewing or swallowing
  • Severe ear pain
  • Difficulty moving the jaw or tongue
  • Hoarseness
  • Numbness of the tongue or other areas of the mouth
  • Dentures fit poorly or become uncomfortable because the jaw is swollen


Causes and Risk Factors

  • Tobacco (cigarettes or smokeless) and alcohol use greatly increases the risk of contracting buccal mucosa cancer
  • More common in men
  • Occurs in women who use snuff
  • More likely to occur at 50 to 80 years of age but can develop at any time

Diagnosis

A doctor will examine the inside of the mouth and back of the throat to check the location and size of the tumor. Examination of the ears, nose and neck are needed to help determine if the tumor has spread.

The doctor may also order other tests including:

  • Blood tests
  • X-rays to determine if the tumor has spread to the lung
  • Fine Needle Aspiration Biopsy (FNA). A thin needle is placed in the mouth. The cells are aspirated (suctioned) and then examined under a microscope to determine if the lump is cancerous
  • Imaging studies to determine if the tumor has invaded nearby tissues or other organs of the body. These may include:
    • Computerized tomography (CT) scan. A computer is linked to an X-ray machine which creates a series of detailed pictures, with different angles, of areas inside the mouth and neck. A dye may be injected into a vein or a pill swallowed to help highlight the organs or tissue on the X-ray. This procedure may also be referred to as computerized axial tomography (CAT).
    • Magnetic resonance imaging (MRI). This machine uses a magnet, radio waves and a computer to create detailed pictures of the area inside the mouth and neck. This procedure may also be referred to as nuclear magnetic resonance imaging (NMRI).
    • Positron emission tomography (PET) scan. During a PET scan, a small amount of radioactive glucose (sugar) is injected into a vein. The scanner creates computerized pictures of the areas inside the body. Cancer cells absorb more radioactive glucose than normal cells so the tumor is highlighted on the pictures.

Treatments

Early-stage cancer of the buccal mucosa is often treated with surgery. Advanced cancer cases may require a combination of surgery and chemotherapy.
