A lot of "HMO" type (cost optimized) medical advice and wishful thinking posted in this thread.
There is much involved with PSA data and the tests and uses are evolving.
I suggest you do plenty of your own research; you will get some poor and contradictory advice, even from the physicians - if your best tool is a hammer, most problems will be seen as nails. Guess what a cancer specialist in radiology will recommend!
From my experience, the biopsy procedure was a trivial procedure - less pain than some of my blood donation experiences. Do not fear it.
If indicated, get the treatment you need, not what the medical statistics indicate for the overall population. It is your body and your life.
Many continue to die OF prostate cancer (not with) and from my research it is a miserable way to die.
If you need surgery (the so called "gold standard" treatment), find a good, experienced surgeon - your future quality of life depends upon it. If the cancer remains within the capsule (early detection is the key) a good surgeon can often get all the bad stuff (full cure) and leave all the "good stuff" intact.
For more information on the topic the below link is one place to start; I also recommend Dr Walsh's (of John Hopkins) book on the topic.
