As others have suggested a PSA check five weeks post op is on the early side. This is what our site says:
At four to eight weeks after surgery, your PSA level should drop so low that it’s not possible to detect it (less than 0.1 ng/ml). This is because the prostate, which produces PSA, has been removed. A rise in your PSA level may suggest that you still have some prostate cancer cells.
Best of luck with you consultation today and please keep us updated.👍
