Hardening of the prostate can also be due to benign prostatic hyperplasia; around 20–25% of those with abnormal findings on their rectal exams have prostate cancer. [25] Several urological societies' guidelines recommend magnetic resonance imaging (MRI) to evaluate the prostate for potential tumors in men with high PSA levels. MRI results can ...
