This article reminds me of a good book I read called Risk Savvy that cites a ton of examples (including breast cancer) of healthcare providers making poor decisions based on their misunderstanding of basic statistics and probability. It's a great read, and the author reviews a bunch of historical medical data that made me rethink how I get screened and how I would make decisions based on my test results. The book also covers a bunch of other topics to help you make better data-driven choices, although I did think it was a little repetitive.
