Introduction Larynx is an anatomically complex organ. Glottis, supraglottis and subglottis are, in order of relative importance, the most frequent tumor locations, which are clinically characterized by the way they affect the main functions of the larynx: phonation and deglutition. Objectives the present paper describes the frequency, socio-demographic and tumorous characteristics of laryngeal cancer cases in Cuba. Methods A descriptive study was conducted, taking the new laryngeal cancer cases reported to the National Register of Cancer from 1988 to 2003 as a basis. Social and demographic information of cases and other variables related to diagnosis and to the tumorous disease were analyzed. Chi-square test of independence determined the association of variables under study, with significance level equal to0,05. Results Laryngeal cancer is one of the first causes of incidence and mortality due to cancer in Cuba, mainly in males aged 50-74 years. Although subglottis cancer is rare, glottis cancer is up to three times as frequent as that of supraglottis. Conclusions Glottis cancer shows early symptoms, so it can be detected on a relatively simple examination. Considering the Cuban health system characteristics, this event could open up possibilities for early detection, therefore, it would be advisable to evaluate the feasibility and efficacy of the otorhinolaryngology test -as part of the annual systematic examination -mainly in men aged 50 years and more, with history of smoking/alcoholism, in order to detect and treat the disease early.
