My brother had a 6.8 psa and spread outside of the prostate. He had Mridian viewray treatment in December/ January plus adt. As of a week ago, his psa was .13. My psa was 10.2 and I had Mridian treatment finish in February (diagnosis said cancer contained within the prostate) with no adt (though 1 RO suggested adt because of my psa) and I will have a psa test in June or sooner but it takes a while for the radiation to work through your system.
