[Prostate cancer screening in the general population: the drawbacks are certain but the benefits are hypothetical].

The main drawback of prostate cancer screening is overdiagnosis i.e. the detection of cancers that would never have become symptomatic; their treatment leads in many cases to impotence or urinary incontinence. Prostate cancer screening cannot be recommended at the present time because it has not yet been shown to reduce mortality from prostate cancer. The first results on mortality from 2 large trials of prostate cancer screening, conducted in Europe and in the United States, will not be available before 2008.
