PSA Density and Lesion Volume: Key Factors in Avoiding Unnecessary Biopsies for PI-RADS 3 Lesions.

Introduction: The use of multiparametric magnetic resonance imaging (MRI) to guide prostate biopsies has improved cancer detection rates, particularly for high-grade tumors. However, despite guidelines recommending biopsies for lesions with a Prostate Imaging-Reporting and Data System (PI-RADS) score ≥ 3, the clinical significance of PI-RADS 3 lesions remains uncertain. This uncertainty, coupled with the cost and potential complications of biopsies, underscores the need for more accurate risk stratification strategies to avoid unnecessary procedures.
