Hi! My father is 81 year old and has been diagnosed with advanced prostate cancer in october 2017. One bone met and one lymph node affected. PSA 4.48. He underwent brachytherapy in april 2015 and the psa fell to 1.27 but started rising in october (2.88). Gleason 7 (3+4). The doctor has prescribed him triptolerin and doesn´t want to treat him with radiation (too old). Concerned about the evolution. First psa and testosterone control at the end of January.
