Prostate Cancer :: Exploring causes for declining prostate cancer mortality rates in US between 1993 and 2003

Researchers from the University of Alabama, Birmingham, sought to compare declining prostate cancer mortality rates with the independent epidemiological variables including prostate-specific antigen (PSA) screening, insurance coverage, obesity, diabetes and hyperlipidemia (high cholesterol levels).

Results of the study showed a direct correlation between prostate-cancer mortality rates with hyperlipidemia and PSA screening in white men, and health insurance coverage in black men. The link between high cholesterol and declining mortality was unexpected, and researchers attribute this relationship to the increased use of statin medications to treat high cholesterol.
