Oral cancer is a common cancer of global concern. It is known to be a devastating disease of tremendous consequence to the individual, to family and to society. Every year more than 3 lakh people diagnosed with oral or pharyngeal cancer in India. Of these, it is estimated that majority can be potentially be detected by a dentist. The five-year survival rate is approximately 50 per cent for advanced stage oral cancers Early detection has the potential to significantly reduce oral cancer deaths and morbidity. Known risk factors include tobacco and alcohol consumption, together responsible for about 75 per cent of oral cancers in India. Most oral premalignant lesions and cancers should be detectable at the time of a comprehensive oral examination. These lesions often present as a white patch or, less frequently, a red patch. Progression from premalignant lesions to cancer usually occurs over years.

Approach: Oral Cancer screening and Mucosal Lesion Assessment

Patient History

Visual screening Examination

Diagnostic Biopsy

1. Patient History

The first step in screening for oral cancer is the completion of a patient history, which should include review of:

  • General health history including a list of current medications and medication allergies
  • Oral habits and lifestyle, with particular reference to quantity, frequency and duration of tobacco use and alcohol consumption
    Symptoms of oral pain or discomfort.

2. Visual screening Examination

Extraoral examination:

  • Inspect the head and neck region for asymmetry, tenderness or swelling.
  • Palpate the submandibular, neck and supraclavicular regions for lymph nodes, paying particular attention to size, number, tenderness and mobility.
  • Inspect and palpate the lips and perioral tissues for abnormalities.

Intraoral examination:

  • Systematically inspect and palpate all oral soft tissues, paying particular attention to the high-risk sites for the development of oral cancer including the lateral and ventral aspects of the tongue, floor of mouth and the soft palate complex.

Lesion Inspection

  • Evaluate the specific characteristics of each lesion with particular attention to size, colour, texture and outline. Particular attention to predominantly white, re


  • At the time of initial assessment and at each re-evaluation appointment, it is recommended that an image of any clinically visible lesion be obtained and a lesion tracking sheet be completed.

3. Diagnostic Biopsy

If a suspicious mucosal lesion persists for more than three weeks following removal of identified local irritants such as trauma, infection or inflammation, diagnostic biopsy is required. Alternatively, referral Asian Head Neck Cancer Foundation expert Team of Surgeons.

Tissue biopsy remains the gold standard for diagnosing an oral premalignant lesion or oral cancer. A carefully selected, performed and interpreted biopsy is critical in rendering an accurate diagnosis.

If biopsy-proven dysplasia is identified, an oral risk assessment is recommended to determine appropriate management. This may range from long-term monitoring to medical or surgical therapy.
