Having been diagnosed in September with aggressive prostrate cancel my PSA level result from my lst blood test was 37.1 . Have Been put on hormone injections. 6 weeks ago my recent PSA score was an amazing 0.48 . I am so very confused how this can be such a dramatic drop in such a short time .Especially as l,m supposed to be on injections for 3 months before radiotherapy . Can anybody throw sum light on this?
