You may be aware of the recent announcement by the National Screening Committee of their decision not to recommend the development of a screening programme for prostate cancer. For the reasons listed below, we believe that the decision that was made was the wrong one and that if the committee had considered the latest evidence, and had not made invalid assumptions and inaccuracies, that they would have concluded that the evidence in favour of screening for prostate cancer now clearly outweighs that against it. We believe that this conclusion should be challenged by all who have at heart the well being of men at risk of prostate cancer.
