More than 200 chemicals - many found in urban air and everyday consumer products - cause breast cancer in animal tests, according to a compilation of scientific reports published Monday.
Writing in a publication of the American Cancer Society, researchers concluded that reducing exposure to the compounds could prevent many women from developing the disease. The research team from five institutions analyzed a growing body of evidence that linked environmental contaminants to breast cancer, the leading killer of U.S. women in their late 30s to early 50s.
