Epidemiology of laryngeal cancer

Abstract

Laryngeal cancer is the second most common respiratory cancer after lung cancer. Its incidence is increasing over time in much of the world and this increase is generally accepted to be related to changes in tobacco and alcohol consumption. It is a relatively common cancer in men, but rarer in women. Moreover, interesting new issues have been raised recently about the influence of other possible risk factors. Evidence from epidemiological studies which supports the involvement of new risk factors in the aetiology of larynx cancer, as well as new perspectives in therapy, must be taken into consideration in order to realise primary and tertiary prevention. However, it remains clear that, even as new evidence continues to amass about a wide range of risk factors, primary prevention of the great majority of laryngeal cancers could be achieved by elimination of tobacco smoking and reduction of consumption of alcoholic beverages. With an additional contribution from adoption of a diet rich in fruits and vegetables, the great majority of laryngeal cancer appears to be preventable within our current epidemiological knowledge.
