Analysis of cohort mortality from prostatic cancer in Spain, 1951-1983.

Prostatic cancer mortality rates in Spain were analysed for the period 1951-1983 by age groups. Five year interval age cohort trends were also studied. A rising trend was seen over this period of time, although there has been some stabilisation during the recent past. Age cohort analysis shows a generation effect in those cohorts born before 1896, consistent with an increased exposure to environmental and/or occupational factors.
