Roofers have higher levels of cancer. University of Colorado Cancer Center study explores why.

Roofers and road construction workers who use hot asphalt are exposed to high levels of polycyclic aromatic hydrocarbons (PAHs). A University of Colorado Cancer Center study published this week in the British Medical Journal Open shows that roofers have higher PAH blood-levels after working a shift and that these high levels of PAHs are linked with increased rates of DNA damage, and potentially with higher cancer risk.
