Pollution linked to child cancer risk

Being exposed to environmental pollution while in the womb could increase a child's risk of getting cancer, a recent study suggests. As the BBC http://www.bbc.co.uk reports, children born near emission "hotspots" were more likely to die of cancer before the age of 16 than others. Despite the study's lack of conclusive evidence, the author, George Knox from the University of Birmingham http://www.bham.ac.uk , believes the threat is very real. However, cancer experts warn that the research contains many flaws and are urging caution.
