I agree with JNF - a biopsy is premature. However, I can certainly see why his doctors are puzzled by a grossly enlarged prostate in a 40 yo man - that is very unusual. I hope he his taking Proscar or Avodart. That will reduce the size of his prostate over time, and get him peeing better. But they take time to work - about 4-6 months to have a measurable effect. It has a couple of side benefits:
(1) it reduces the PSA output due to enlarged prostate (BPH) but doesn't have much effect on any pSA that may be coming from prostate cancer. Rule of thumb is that PSA is reduced by about half. if it doesn't go down, or if it goes down and then comes back up - that would be a good sign that a biopsy is in order.
(2) it prevents low grade prostate cancer, and some think it may be able to shrink low grade, insignificant PC that is already there. i have a friend who had a 120 cc prostate with a very small amount of pc on a biopsy. He took Avodart, which reduced his prostate to about 40 cc, and on 2 subsequent biopsies, they have not been able to find any signs of cancer. He wishes he'd never had the first biopsy.
(3) If after ruling out the more obvious causes of increased PSA he decides to have a biopsy, the biopsy is more likely to detect anything that may be there if his prostate is reduced in size. It's easier to find a needle in a smaller haystack.
Another step he can take is to ask for a Prostate Health Index (PHI) test next time instead of just a PSA (it includes PSA and a lot more). It is inexpensive and covered by insurance. Importantly, it is less affected by BPH and more specific to prostate cancer, so it can help him avoid an unnecessary biopsy.
