[Bladder cancer: study of mortality in Spain (1968-1982)].

In review of the rising bladder cancer mortality rate in Spain and its involvement in connection with other "risk factors", according to recent contributions, we proceeded to review these factors involved and to carry out an epidemiological study describing its mortality from 1968 to 1982, through specific mortality rates per hundred thousand in males and females, as well as the study by age groups from 50 upwards, concentrating on more highly affected ages. We also carried out transverse studies for the three years 1968, 1975 and 1982 and reviewed the evolution of mortality in accordance with the chorts of births. On the whole, we observe a continual rise in mortality due to this cancer, at a much higher level in the masculine sex, and we make interpretation as to its association with "risk factors" connected with life style.
