Trends in prostate cancer incidence among men 75 years and older may reflect a number of factors other than changes in screening recommendations. For this reason, my colleagues and I compared trends in the incidence of prostate cancer among men 75 years and older with trends among men aged 65 to 74 years, who served as a concurrent control group. This topic merits further investigation, and we are currently undertaking a direct examination of trends in prostate cancer screening rates.
