A follow-up of cancer incidence among former Finnish dump site residents: 1999-2011

摘要

Background: In an analysis of the years 1976-1998, a 50% excess in cancer incidence was observedamong residents in twelve blockhouses in Helsinki, Finland on a former dump area containing industrial andhousehold waste.Objective: To assess cancer risk over a 13-year period 1999-2011 among residents formerly living inhouses built on a dump area.Methods: All 1879 persons who ever lived in the former dump area were identified and the number ofcancer cases in this population was obtained from the Finnish Cancer Registry.Results: After 5 years of residence at the dump site, the standardized incidence ratio of cancer (all sitescombined) was 1.32 (95% Cl: 0.94-1.79) in men and 0.53 (95% Cl: 0.33-0.82) for women, in comparisonwith the general Helsinki population (1999-2011). No significant excess cancer risks were found.Conclusions: Residing on a former dump area was not found to result in an increased risk of cancer.
