Diesel fumes cause cancer

The risk of getting cancer from diesel fumes is small, but since so many people breathe in the fumes in some way, the science panel said raising the status of diesel exhaust to carcinogen from “probable carcinogen” was an important shift. 

“It's on the same order of magnitude as passive smoking,” said Dr Kurt Straif, director of the International Agency for Research on Cancer (IARC) department that evaluates cancer risks. “This could be another big push for countries to clean up exhaust from diesel engines.”
