Air pollution linked to higher breast cancer risk: Canadian study

Polluted air may boost the risk of breast cancer, According to a new Canadian study.

The study tracked nearly 90,000 Canadian women over two decades and found that younger women who live in areas that experience high air pollution had a staggering 30 percent higher risk of developing breast cancer before menopause than others.

Carleton University health sciences researcher Dr. Paul Villeneuve, an author of the study, told Canadian CTV News Network that researchers suspect that tiny particles in polluted air may promote inflammation or make breasts denser and thus more prone to developing tumours.

The believe that the link between pollution and breast cancer is pronounced among women before menopause because their hormones are more active then and may interact more with chemicals in the environment, added Villeneuve.

He noted that the best prevention would be a worldwide reduction in air pollution.

According to the World Health Organization, around seven million people die every year from being exposed to fine particles in polluted air.
