Two strongest environmental breast cancer risks

A new study published in the August issue of Archives of Internal Medicine concluded that the two most important environmental risks for breast cancer are avoiding and reducing exposure to medical radiation and postmenopausal hormone therapy. In fact, the Institute of Medicine stated that reducing exposure to medical radiation "is one of the primary evidence-based actions that could reduce breast cancer risk, and the medical community should do everything in our power to reduce unnecessary exposures as quickly as possible."

Bonnie: The IOM targeted CT scans specifically, mostly because they deem many of them unnecessary and pushed purely for financial gain. Strong stuff.
