Mammograms are validated to have an association with a decrease in breast cancer deaths. “The study, being published today in The New England Journal of Medicine, concludes that 28 to 65 percent of the sharp decrease in breast cancer deaths from 1990 to 2000 was due to mammograms. The rest was attributed to powerful new drugs to treat breast cancer.”
We’ll have the data next for PSA and prostate cancer screening. As it stands, only mammograms and fecal occult blood tests for colon cancer screening are associated with a mortality benefit.
