The risk of ovarian cancer increases with increased exposure to diesel exhaust at work, according to a new study. Writing in the International Journal of Cancer, a research team from the Finnish Institute of Occupational Health describe how they assessed the risk a variety of cancers possibly linked to engine exhaust exposure. These included leukaemia and cancers of the throat, ovaries, testes, kidney and bladder. It found individuals with the highest cumulative exposure to diesel exhaust had more than 3.5 times the risk of ovarian cancer.
