Researchers from the Institute of Medicine in the U.S. report that exposure to benzene, 1,3-butadiene and ethyleneoxide, may result in an increased risk of breast cancer. These substances can among others be found in gasoline vapors, diesel exhaust fumes, tobacco smoke and at certain workplaces.
The report does not clarify the possible risks posed by bisphenol A, pesticides, ingredients in cosmetics, and other chemicals that are suspected to have a role in the development of breast cancer. The researchers indicate that more research is needed to get insight in the effects of night shifts, mutagenic substances and endocrine disrupters.
A healthy weight, exercising regularly, limiting alcohol and avoiding tobacco and unnecessary medical radiation are a few ways that women can reduce breast cancer risk, the report said.
