The major causes of an elevated serum PSA include:
* Benign prostatic hyperplasia (BPH)
* Prostate cancer
* Prostatic inflammation
* Perineal trauma
Certainly, any rise in PSA readings is of concern and warrants further evaluation. A lower free PSA percentage is associated with an increased risk of aggressive cancer.
As to "false PSA", it may be due to other causes that can raise the PSA. A simple digital rectal exam can elevate the PSA.
I would consider a urology referral for further evaluation and to consider a prostate biopsy.
Followup with your personal physician is essential.
