Bite Back at Mouth Cancer – What to Look for and How

Many people are unaware that, in its very early stages, mouth cancers can be almost invisible making them easy to ignore. This is why it’s so important to keep a close eye on the health of your mouth as the chances of survival are significantly improved if the cancer is detected early and rapidly treated.

To make it easier to check for mouth cancer, the Mouth Cancer Foundation has come up with a new life-saving initiative called ‘Bite Back at Mouth Cancer’ – a do-it-yourself check which may just save your life!

It’s recommended that everyone over the age of 16 does this two minute self-check once a month, after teeth have been cleaned. All you need to carry out the mouth test is:

  •   A mirror
  •   A good light source
  •  Clean fingers.

At each step you are inspecting and feeling for any lumps, red or white patches and changes in colour or texture, lingering ulcers or anything unusual.


Mouth Cancer Action Month

Look at the whole face.

  •  Are there any swellings you haven’t noticed before?
  •  Inspect your skin. Has anything changed recently?
  •  Have moles become larger or started to itch or bleed?
  •  Turn your head from side to side. This stretches the skin over the muscles making lumps easier to see.
  • Run the fingers under your jaw and feel along the large muscle either side of neck using the balls of your fingers. Are there any swellings? Does everything feel the same on both sides?

If you find anything during your check that raises any concerns, visit your dentist or doctor to seek their opinion. The Mouth Cancer Foundation recommends that everyone over the age of 16 sees their dentist once a year to check for early signs of mouth cancer.
