title: Prostate cancer mortality rates compared to urologist population densities and prostate-specific antigen screening levels on a state-by-state basis in the United States of America.
abstract: We hypothesized that prostate cancer screening and availability of urologists among states may be associated with reduced prostate cancer mortality in the United States. To test this hypothesis, state-specific prostate cancer mortality rates for white males were compared to urologist population densities and prostate-specific antigen (PSA) screening rates on a state-by-state basis. The urologist population density was calculated by dividing the number of urologists per state by the population. We found that prostate cancer mortality rates correlated inversely with urologist population densities (P<0.01) and PSA screening (P<0.01) suggesting that screening and treatment reduce prostate cancer mortality.
