Population-based study assesses rising prostate cancer rates, linking it to increased detection methods.

This research aims to understand why prostate cancer incidence surged dramatically from 1986 to 1991.
Population-based study using Medicare claims and SEER program data from 1986 to 1991
Sample included a 5% random sample of male Medicare beneficiaries aged 65 and older
Focus on age-adjusted incidence rates and detection procedures
Prostate cancer incidence rose 82% among men aged 65+ from 1986 to 1991, with annual increases peaking at 20% and 19% in 1990 and 1991, respectively.
Increased rates of prostate needle biopsy coincided with a surge in PSA testing from 1988 to 1991.
Geographic variability in PSA screening persist despite overall increases across ages and races.

Arnold L. Potosky (1995) studied this question.
