Is it true that a prostate biopsy is really dangerous?

See answer. Prostate cancer (pca) is 2nd leading cause cancer death. Prostate bx is essential procedure for detecting pca and coupled with appropriate screening and informed consent, prostate biopsy and early detection saves lives. Though generally safe and well-tolerated, there are associated risks: severe infection requiring hospitalization (1-4%); significant bleeding (1-4%); and urinary retention (1%).
No. But it is likely to be unpleasant and a biopsy series may interfere with function afterwards. Around 1% of men have significant bleeding and/or urinary retention afterwards. Especially if a man has a minimal elevated in psa and no palpable lesion, it's his informed choice whether to have a biopsy.
