Prostate cancer is an issue with a LARGE literature about it. I will try to post to you something about it.
Try these sites:
www.prostatecancerfoundation.org
and
www.nlm.nih.gov/medlineplus/prostatecancer.html
If you have an enlarged prostate, the sooner you have it attended to the better. If it's left there's the possibility of cancer, or at least an ongoing problem with urination.
