Bladder cancer in Spain. Mortality trends (1955-1975)

Studies made of mortality tendencies due to bladder cancer made in various industrialized countries show evidence of an increase with time in death rates. This situation is also seen in Spain with some characteristics which we analyze. An actual increase of 60% in risk of death due to bladder cancer in males was found between 1955 and 1975. A definite tendency in women was not observed. The characteristics of the tendency curves indicate the grave importance that this tumor could eventually have in Spain and the need to adopt a policy of adequate intervention.
