Diesel Fumes Increase Ovarian Cancer Risk - Oncology Study

[hatrack]

NEW YORK - "The risk of ovarian cancer increases with increased exposure to diesel exhaust, according to a new study published in the International Journal of Cancer.

"Occupational exposure to diesel exhaust has been classified as probably carcinogenic and that to gasoline engine exhaust as possibly carcinogenic to humans," Dr. Johannes Guo, of the Finnish Institute of Occupational Health, Helsinki, and colleagues write. "Earlier results concerning cancers other than lung cancer are scarce and inconsistent, and exposure-response relations have seldom been reported."

The researchers assessed the risk a variety of cancers than may be associated with engine exhaust exposure. These included leukemia and cancers of the throat, ovaries, testes, kidney and bladder.

EDIT

Using data from the population census in 1970, they calculated cumulative exposure (CE) to exposure to diesel and gasoline engine exhausts. They detected a significant increased risk of ovarian cancer with increasing CE to diesel exhaust. Individuals with the highest CE had more than 3.5 times the risk of ovarian cancer. For exposure to gasoline engine exhaust, the risk was significantly increased only in those who were in the middle CE category. These individuals had a 70 percent increased risk."
