[Epidemiologic study of mortality caused by cancer of the larynx in Spain, from 1951 to 1983].

We have reviewed the mortality from laryngeal cancer in Spain (1951-1983). An evident increase of the tendency for males has been observed, while an stabilization in females, with lower rates, has been appreciated. It is reflected in the increase of the sex ratio along the studied period, specially since 1970. Concerning the morbidity, through hospital diagnostic data in Spain, as much the absolute numbers as the corresponding morbidity rates have been clearly increasing in males, specially during the last years of our study (1977-1985).
