Mouth cancer can affect the way a person eats, speaks, and even breathes. It can lead to severe pain, disfigurement, and emotional distress. Sadly, the number of cases worldwide is rising.
In the UK alone, cases of mouth cancer have more than doubled in the last generation, making it one of the fastest-growing types of cancer. Despite this, public awareness remains low, and too many cases go undiagnosed until it is too late.
Early detection saves lives, and that’s why today, on World Cancer Day, we want to highlight the key symptoms of mouth cancer and what you should do if you spot anything unusual.

Symptoms of mouth cancer

Mouth cancer can appear in different forms, which is why it’s so important to know what to look out for. The most common signs include:

• Ulcers that do not heal within three weeks.

• Red or white patches in the mouth.

• Lumps or swellings in the mouth, lips, or throat.

• Persistent hoarseness or difficulty swallowing.

• Unexplained numbness, pain, or bleeding in the mouth.

  
  

  Where can mouth cancer appear?

  Mouth cancer can develop in several areas of the mouth and surrounding regions, including:

• The lips.

• The tongue (especially the sides and underneath).

• The gums.

• The inside of the cheeks.

• The roof or floor of the mouth.

• The tonsils and throat.
  
  

  If you notice anything unusual, don’t wait. Early detection greatly improves the chances of successful treatment.
  What to do if you notice symptoms
  If you experience any of these symptoms for more than three weeks, it’s essential to see a dentist or doctor as soon as possible.
  Regular dental check-ups are vital, as dentists are trained to spot the early signs of mouth cancer.
  It’s also important to be aware of your personal risk factors.
  Smoking, excessive alcohol consumption, HPV infection, and poor diet can all increase the likelihood of developing mouth cancer.
  Making healthier choices can help lower your risk.
