After 12 months of slowly rising PSA during 2015 (reaching 0.13 in November) I had 4 weeks of RT in January this year. I was fortunate not to suffer any side effects and by March my PSA had reduced to 0.06 - the most recent test result was 0.02 so the RT seems to be doing its thing. I'm under no illusions about the future but hope my experiance gives some of you hope that treatments can be effective despite a grim diagnosis.
