Research age specific PSA. My understanding is that for a man in his 50's the PSA should average 0.9 if there is no inflamation, enlargement, cancer, etc. This is taken from Dr Catalona's website:
"Rather than consider the PSA range in terms of "normal or abnormal," it is more useful to consider it as a means of assessing the risk that prostate cancer would be found on a biopsy.
For instance, regardless of age, if a man has a perfectly healthy prostate gland (without inflammation, benign enlargement or cancer) the PSA should be very low - certainly less than 2. Our studies showed than the median PSA level is 0.7 for men in their 40s, 0.9 for men in their 50s and 1.4 for men in their 60s.
If there is cancer, inflammation, or benign enlargement, or a combination of these conditions, the PSA level will be higher.
If the PSA is in the 2.5-4 range, the chances of finding cancer on biopsy are about 25%. If the PSA is 4-10, the chances of finding cancer are 35-40%. If the PSA is higher than 10, the chances of finding cancer are about 60%."
