Oral Cancer

About oral cancer

Oral cancer is an increasingly common disease which has little understanding among the general public. In 2012, there were 61,400 new cases of oral cancer in Europe, proving this disease to be a cause for serious concern. Furthermore, oral cancer incidence has increased by 25% in the last 10 years. Oral cancers account for 2% of cancers worldwide, which totals 300,000 cases per year.

Oral cancer refers to cancers that start in the mouth. This includes the:

  • Inside lining of the cheeks and lips

  • Front two-thirds of the tongue

  • Gums

  • Floor of the mouth

  • Roof of the mouth

  • Area behind the wisdom teeth

Another major concern is that over half of oral cancer cases present at an advanced stage; as a result treatment is very complex and can be less effective. Only 30–40% of patients are cured of advanced stage oral cancer, and even in the survivors there are permanent and unavoidable effects on the mouth, causing problems with chewing, swallowing and speech. The good news for those patients who get help early is that treatment is simpler, cure rates are very good (about 80%) and functional problems are much less serious.

One of the reasons patients present late is thought to be the poor stigma associated with oral cancer, and that the potential seriousness of their symptoms is not appreciated.

SYMPTOMS

The two most common symptoms of mouth cancer are:

  • An ulcer or lump in the mouth that will not heal (80% of people with mouth cancer have this symptom)

  • Discomfort or pain in the mouth that will not go away

Other symptoms can include:

  • A painless lump in the neck: increasingly important with rising HPV-related cases

  • A white or red patch in the mouth or throat that will not go away

  • Difficulty or pain with chewing or swallowing

  • A feeling that something is caught in the throat

  • Unusual bleeding or numbness in the mouth

  • Loss of teeth for no apparent reason

  • Difficulty moving the jaw

  • Speech problems

  • Weight loss

  • Bad breath (halitosis)

DIAGNOSIS

Less serious conditions than cancer may cause many of the above mentioned symptoms, but it is important to report any symptoms to your doctor or dentist. Dentists, in particular, have an important role in spotting oral cancer early and encouraging patients to take care of their mouths.

If a doctor or dentist sees a patient with these symptoms, they have rapid access to a network of specialist centres with particular skills and training in treating mouth cancer.

TREATMENT

Most patients with early stage oral cancer can be treated with minor surgery, from which recovery is often rapid. For more advanced stages, treatment involves combinations of major surgery, radiotherapy and chemotherapy. Research has led to major advances in surgical reconstruction and rehabilitation of the mouth, and of better targeting for radiotherapy and chemotherapy to optimise treatment and minimise patient discomfort.
