Increased Lung and Bladder Cancer Incidence In Adults After In Utero and Early-Life Arsenic Exposure. Cancer Epidemiol Biomarkers Prev. 2014 May 23. pii: cebp.0059.2014.
SUMMARY/ABSTRACT: Background: From 1958-70, >100,000 people in northern Chile were exposed to a well-documented, distinct period of high drinking water arsenic concentrations. We previously reported ecological evidence suggesting that early-life exposure in this population resulted in increased mortality in adults from several outcomes including lung and bladder cancer. Conclusions: Lung and bladder cancer incidence in adults was markedly increased following exposure to arsenic in early-life, even up to 40 years after high exposures ceased. Findings like these have not been identified before for any environmental exposure, and suggest that humans are extraordinarily susceptible to early-life arsenic exposure. Impact: Policies aimed at reducing early-life exposure may help reduce the long-term risks of arsenic-related disease.
