Can prostate problems be prevented?????????????

  Hi--first i'm not talking about STDs----But can anything be done to prevent or delay Prostate problems--ie.. BPH--prostate pain--chronic prostitis?  What about alternative medicines (saw palmetto--zinc--etc.) and vitamins?  what about conventional medicines (proscar--).  There has to be something which can prevent this--I mean if wee can go to the moon and mars and it's almost the year 2000----there has to be something----anything????
  Thank you
