Abstract:
In an unselected population of women in their early fifties, about 7500 mammograms would have to be performed annually at a cost of U.S. $375,000 per survivor in order to find one woman who would: 1) have an incidental cancer in stage I which was not detectable by physical examination; and 2) owe her survival to the early detection of that cancer. Annual screening mammography has a poor cost-benefit ratio.
