What is Mouth Cancer?

Mouth cancer, also referred to as oral cancer, includes malignant tumours which develop in the mouth. Common sites include the tongue, floor of the mouth (under tongue), lip, gums, roof of mouth (palate) and inside of your cheeks. Less commonly it can also affect the throat (pharynx) and voicebox (larynx).

The most common type of mouth cancer (for 9 out of 10 cases) are squamous cell cercinoma. Squamous cells are found around the body such as under the skin and on the inside of the mouth. Other, less common types of oral cancer are oral malignant melanoma (where the cancer starts in melanocyte cells) and adenocarcinomas (salivary glands).

A cancerous cell is defined as a cell that grows uncontrollably and can spread to other parts of the body.


What Can Increase Your Risk of Getting Oral Cancer?

In the UK the most common risk factors for oral cancer are:

  • Alcohol
  • Tobacco

The combined effects of tobacco and alcohol account for around three quarters of  oral cancer cases.

Heavy drinkers and smokers are 38 times more likely to develop the disease.

Other risk factors include:

  • Betel nut, paan and gutkha
  • Low fruit and vegetable diet
  • Human Papillomavirus (HPV)
  • Over exposure to sunlight

Despite this, almost half of oral cancer cases in the UK are preventable. 

What are the Signs and Symptoms of Mouth Cancer?

Mouth cancer can present in different ways, some less obvious than others.

Here are some key warning signs to look out for:

  1. An ulcer in the mouth which does not heal within 3 weeks
  2. A red or white patch in the mouth
  3. Change in voice or speech
  4. Constant sore throat
  5. Numbness or altered sensation on the tongue or lip 
  6. Unexplained lumps, bumps or swellings that do not go away 
  7. Loosening of teeth unexpectedly 

Any of these symptoms could indicate cancer. Do not wait and contact your dentist or GP immediately.

What Can Your Dentist Do?

Your dentist has a vital role in screening for oral cancer. They will perform a detailed examination and assess for any signs or symptoms as well as helping you identify any risk factors for oral cancer at each routine appointment. 

It is important you see your dentist regularly as they can identify any warning signs early and help ensure you get the best care. 

If in doubt, do not wait and make an appointment earlier. Early detection of oral cancer means better chances of survival. 

What Happens If Your Dentist is Concerned?

If your dentist has any suspicions of oral cancer they will promptly refer you to hospital for detailed tests to allow an accurate diagnosis. There you will see a specialist team of oral and maxillofacial surgeons.
