Men aged 55-65 years with neither previous biopsy nor prostate diseases will be invited in the screening protocol and will perform an initial PSA test. Those cases with PSA ≥ 3 ng/ml will be invited to undergo a urologic examination with computed risk assessment and an MRI, which is a non-invasive test with high positive and negative predictive value in identifying clinically significant prostate cancer. Then, only men with medium-high risk of harbouring clinically significant prostate cancer will be invited to undergo a prostate biopsy to indentify cancer presence and its aggressiveness.
