The Danish Cancer Register recorded a significant excess incidence of bladder tumours among men in West Lolland during the period 1970 and 1979. No corresponding excess incidence of cancer of the lung was recorded. This might suggest that causes other than increased prevalence of smokers explain the recorded findings. A case-control investigation was carried out to illustrate possible occupational causal factors with the aid of the Cancer Register database concerning cancer and occupation which is based on linking of the Cancer Register with the Supplementary Pension Fund (additional pensions supplementary pension fund awarded via the Labour Market.) Increased risks of bladder tumours were demonstrated in several occupations which are recognized as involving a risk for this disease. A significantly increased risk was demonstrated in the transport occupation. No evidence was found to suggest that the peculiar occupational structure of the region could explain the excess risk registered.
