A single PSA test is: Rarely an indication for a biopsy, but the pattern of psa and rate of rise calls for biopsy to confirm. Many slight rises lead to bx, with some risks of sepsis, and trivial small foci of low risk cancer that are best observed rather than treated.

How reliable are the screening tests for prostate cancer? Does prostate cancer screening save lives?
Common situation: Everyone seems to agree that psa is not a "perfect" cancer screening test. If it was everyone with psa elevation would be found to have cancer upon biopy and that isnt the case.
