Exposure to common chemicals during critical periods of breast development may affect breast growth, the ability to breast-feed and breast cancer risk, a new report contends.
Scientists from the US National Institutes for Environmental Health Sciences, the Environmental Protection Agency and the Silent Spring Institute collaborated on the report, published online in the journal Environmental Health Perspectives.
Rodents are a reasonable test models and should be used to test for dangers to humans.
The breast can be more sensitive to the chemical exposure than other tissues, and in some cases the male mammary tissue was most sensitive.
Chemical exposure to the developing mammary gland can alter susceptibility to cancer-causing agents.
