Exposing to vehicles’ gas emission might double risk of developing breast cancer

Exhaust gas from cars can double the risk for breast cancer. This is a conclusion of a study from Canada.

Researchers drew 2 maps about the level of air pollution. The amount of nitrogen dioxide (NO2) – a by-product establishing from areas polluted by exhaust fumes of vehicles was showed clearly in these maps.

Maps were drawn from different areas of Montreal city (Canada) in the period of time from 1986 to 1996. After that, addresses of 383 menopausal women having breast cancer and 416 women having other types of cancer had also been considered by investigators from 1996 to 1997. The result of study indicated that the number of women living in areas with highest level of NO2 who were diagnosed of breast cancer were as twice as the number of women living in areas with lowest level of NO2.

Gas emission from vehicles is also at the top of the list of breast cancer carcinogens. It contains PAHs (Polycyclic Aromatic Hydrocarbons) which is a product of burning process and is believed to be associating with breast cancer in male and female.
