• Most people have heard of cancer affecting parts of the body such as lungs and breasts. However, cancer can occur in the mouth, where the disease can affect the lips, tongue, cheeks and throat.

Anyone can be affected by mouth cancer, whether they have their own teeth or not. Mouth cancers are more common in people over 40, particularly men. However, research has shown that mouth cancer is becoming more common in younger patients and in women. There are, on average, 8,000 new cases of mouth cancer diagnosed in the UK each year. The number of new cases of mouth cancer in on the increase.

Yes. Over 2,700 people in the UK die from mouth cancer every year. Many of these deaths could be prevented if the cancer was caught early enough. As it is, people with mouth cancer are more likely to die than those having cervical cancer or melanoma skin cancer.

Most cases of mouth cancer are linked to tobacco and alcohol. Cigarette, cigar and pipe smoking are the main forms of tobacco use in the UK. However, the traditional ethnic habits of chewing tobacco, betel quid, gutkha and paan are particularly dangerous.

Alcohol increases the risk of mouth cancer, and if tobacco and alcohol are consumed together the risk is even greater. Over-exposure to sunlight can also increase the risk of cancer of the lips.

Many recent reports have linked mouth cancer to the human papilomavirus (HPV). HPV is the major cause of cervical cancer and affects the skin that lines the moist areas of the body. HPV can be spread through oral sex, and research now suggests that it could soon rival smoking and drinking as one of the main causes of mouth cancer. Practicing safe sex and limiting the number of partners you have may help reduce your chances of contracting HPV.

If your dentist finds something unusual they will refer you to a consultant at the local hospital, who will carry out a thorough examination of your mouth and throat. A small sample of cells may be gathered from the area (a biopsy), and these cells will be examined under the microscope to see what is wrong.

If the cells are cancerous, more tests will be carried out. These may include overall health checks, blood tests, x-rays or scans. These tests will decide what course of treatment is needed.

If mouth cancer is spotted early, the chances of a complete cure are good, and the smaller the area or ulcer the better the chance of a cure. However, too many people come forward too late, because they do not visit their dentist for regular examinations.

It is important to visit your dentist regularly, as often as they recommend, even if you wear dentures. This is especially important if you smoke and drink alcohol.

When brushing your teeth, look out for any changes in your mouth, and report any red or white patches, or ulcers, that have not cleared up within three weeks.

When exposed to the sun, be sure to use a good protective sun cream, and put the correct type of barrier cream on your lips.

A good diet, rich in vitamins A, C and E, provides protection against the development of mouth cancer. Plenty of fruit and vegetables help the body to protect itself, in general, from most cancers.

Cut down on smoking and alcohol consumption.
