What is Floor of Mouth Cancer?

Floor of Mouth Cancer is a type of oral cancer that develops in the area beneath the tongue, often starting as a small ulcer, lump, or patch that fails to heal. This cancer can affect speech, swallowing, and overall oral function. Most cases are linked to tobacco use, alcohol consumption, or human papillomavirus (HPV) infection. Early detection is crucial because this cancer can spread quickly to nearby lymph nodes and tissues.

Understanding its causes, symptoms, and treatment options helps patients and caregivers recognize warning signs early and seek timely medical care. At THANC Hospital, our multidisciplinary team provides comprehensive evaluation and cutting-edge treatment for oral cancers, including advanced surgical and reconstructive techniques for better recovery and quality of life.

Key Symptoms

Common signs and symptoms of Floor of Mouth Cancer include:

  • Persistent ulcer or sore under the tongue that does not heal
  • Pain, burning, or numbness in the mouth
  • Swelling or thickening in the floor of the mouth
  • Difficulty speaking, chewing, or swallowing
  • Loose teeth or pain around the jaw
  • Lump in the neck (indicating lymph node involvement)
  • Unexplained bleeding in the mouth

When to Seek Medical Help

Seek immediate medical evaluation if you notice:

  • A mouth ulcer lasting longer than two weeks
  • Pain or swelling that worsens over time
  • Difficulty in moving your tongue or jaw

Early diagnosis greatly improves treatment success and long-term outcomes.

Diagnosis of Floor of Mouth Cancer

Accurate diagnosis requires a detailed clinical evaluation and diagnostic imaging.
At THANC Hospital, our specialists use advanced diagnostic tools such as:

  • Oral examination and biopsy – to confirm cancerous cells
  • MRI and CT scans – to assess the extent and depth of the tumor
  • PET-CT – for detecting cancer spread to lymph nodes or distant organs
  • Endoscopy – to examine nearby areas like the tongue and throat

THANC Hospital’s state-of-the-art oncology imaging center ensures precise diagnosis and personalized treatment planning.
