Objective To analyse the trends in opportunistic PSA screening in A ustralia, focusing on younger men (<55 years of age), to examine the effects of this screening on transrectal ultrasonography ( TRUS )‐guided biopsy rates and to determine the nature of prostate cancers ( PC as) being detected.Subjects and Methods All men who received an opportunistic screening PSA test and TRUS ‐guided biopsy between 2001 and 2008 in A ustralia were analysed using data from the A ustralian C ancer registry ( A ustralian I nstitute of H ealth and W elfare) and Medicare databases. The V ictorian cancer registry was used to obtain G leason scores. Age‐standardized and age‐specific rates were calculated, along with the incidence of PC a, and correlated with G leason scores.Results A total 5 174 031 PSA tests detected 128 167 PC as in the period 2001–2008. During this period, PSA testing increased by 146% (a mean of 4629 tests per 100 000 men annually), with 80 and 59% increases in the rates of TRUS ‐guided biopsy and incidence of PC a, respectively. The highest increases in PSA screening occurred in men <55 years old and up to 1101 men had to be screened to detect one incident case of PC a (0.01%). Screening resulted in two thirds of men aged <55 years receiving a negative TRUS biopsy. There was no correlation with G leason >7 tumours in patients aged <55 years.Conclusion Despite the ongoing controversy about the merits of PCa screening, there was an increase in PSA testing, especially in men <55 years old, leading to a modestly higher incidence of PC a in A ustralia. Overall, PSA screening was associated with high rates of negative TRUS ‐biopsy and the detection of low/intermediate grade PCa among younger patients.
