Common chemicals found to cause breast cancer in rats: study

WASHINGTON--Certain chemicals that are common in everyday life have been shown to cause breast cancer in lab rats and are likely to do the same in women, U.S. researchers said Monday.
The paper in the peer-reviewed journal Environmental Health Perspectives lists 17 chemicals to avoid and offers women advice on how to minimize their exposure.
They include chemicals in gasoline, diesel and other vehicle exhaust, flame retardants, stain-resistant textiles, paint removers, and disinfection byproducts in drinking water.
"The study provides a road map for breast cancer prevention by identifying high-priority chemicals that women are most commonly exposed to and demonstrates how to measure exposure," said study author Ruthann Rudel, research director of the Silent Spring Institute.
"This information will guide efforts to reduce exposure to chemicals linked to breast cancer, and help researchers study how women are being affected," she said.
Some of the biggest sources of mammary carcinogens in the environment are benzene and butadiene, which can come from vehicle exhaust, lawn equipment, tobacco smoke and charred food.
Other concerns are cleaning solvents like methylene chloride, pharmaceuticals used in hormone replacement therapy, some flame retardants, chemicals in stain-resistant textiles and nonstick coatings, and styrene which comes from tobacco smoke and is also used to make Styrofoam, the study said.
Carcinogens can also be found in drinking water, researchers said.
Every Woman Exposed
"Every woman in America has been exposed to chemicals that may increase her risk of getting breast cancer," said co-author Julia Brody.
"Unfortunately, the link between toxic chemicals and breast cancer has largely been ignored. Reducing chemical exposures could save many, many women's lives."
Brody described the paper as the first to comprehensively list potential breast carcinogens and detail ways for experts to measure them in women's blood and urine.
