Floor of the MouthCancer


Floor of the mouth cancer is a cancer that grows in the tissue under the tongue, near the lower jaw bone (mandible). 

Drinking alcohol and smoking can increase your risk for this cancer. Human papilloma virus (HPV) and human immunodeficiency virus (HIV) can also cause floor of the mouth cancer.


There may be no symptoms in the early stages of floor of the mouth cancer. Many people mistake it for a canker sore. 

During later stages of the disease, symptoms may include: 

  • A sore that continues to grow larger
  • Difficulty moving your jaw
  • Jaw pain or swelling
  • Loose teeth or pain around your teeth
  • Painless lump or ulcer in the mouth
  • Severe ear pain
  • White, red or dark patches inside the mouth


It’s important you get this oral cancer treated as soon as possible, or it could spread into your neck.
