I do not. There is a constituency claiming that they prevent prostate cancer, help with symptoms from an enlarged prostate, and make PSA testing more accurate. My take on the data is that these drugs can suppress BPH (enlarged prostate) and low-grade prostate cancer but they can’t affect high-grade cancer. Accordingly, with prostate cancer, the PSA can go down for a while and the prostate gland shrinks until the high-grade cancer that is more aggressive and resistant to hormonal therapy becomes the dominant player. Patients may not be doing themselves a favor by using Avodart or Proscar to prevent prostate cancer. And I seldom recommend them for BPH (only when all else has failed and the patient appears to be in danger of developing urinary retention or requiring surgery) because they can lower the PSA and disguise prostate cancer detection until the more aggressive cancer takes over, and then treatment is often too late
