20-year results from breast cancer screening program show a significant drop in deaths, limited harm and reasonable costs

Results from the Dutch national breast cancer screening program, one of longest-running national screening programs in the world, have shown that it has contributed to a drop in deaths from the disease, that any harm caused by the screening, such as false positives and over-diagnosis, has been limited, and that the costs have been reasonable. Compared with the pre-screening period 1986 to 1988, deaths from breast cancer among women aged 55-79 fell by 31 percent in 2009.
