Migration patterns of children with cancer in britain

摘要

Conclusions-The main findings of an earlier study, based upon a different and independent method, were confirmed. Proximities to several types of industrial source, around the time of birth, were fol- lowed by a raised risk of childhood cancer. Combustion products and volatile organic Compounds were especially implicated. Within the 16 year limit of the study, the increased risk did no decay with advanc- ing age. Low atmospheric concentrations of may carcinogenic substances suggest that the mother acts as a cumulative filter and passes them to the fetus across the placenta or in breast milk.
