Q | how is the success of treatment monitored?
A | Clinical examination and testing of your PSA levels will be carried out at regular intervals. For example, after radical prostatectomy, your PSA should drop to almost unrecordable levels, ideally to below <0.1. Be aware that different laboratories have different reference ranges and therefore the actually PSA number may be slightly higher than the above.
If after treatment of a localised prostate cancer, your PSA remains at this low level for three years, you can usually assume that the cancer will not come back and that you are cured.
