But I am not surprised.
When mammograms were first introduced, it was really difficult for anyone to refute the arguments that more screenings mean more lives saved. Of course in the process, more sales of mammography machines, more money to screening clinics and more money to breast surgeons. All happy, of course.... except the women who had to undergo needless breast surgeries. They were a small price to pay for the peace of minds of everyone else, apparently.
So now we know.
