“We’re hoping that the stunning financial cost of this problem will help cast into greater belief the human cost—$4 billion tells you that it’s a very large problem, that it’s really happening at a massive scale,” said Mandl, a professor at Harvard Medical School and the Boston Children’s Hospital Chair in Biomedical Informatics and Population. His co-author, Ong, is a research fellow at the Boston Children’s Hospital.

Mandl spoke with Matthew Ong, a reporter with The Cancer Letter.

In 2009, the U.S. Preventive Services Task Force advised against routine screening … Continue reading 41-16 Mandl: Costs of Harm from Mammography Must Be Balanced Against Benefits
