My step-father says his PSA level is 4000. His latest test was in April 2010. In January his test result was a PSA level of 3400. I have seen no change in his daily routine and he says he is not in pain, other than normal issues for a 75 year old man. What does a 4000 PSA level mean? He was diagnosed with Prostate Cancer, but it went into remission, until about a year ago.
