My father was diagnosed a year ago with metastatic prostatic cancer, it spread to his spine. He has already had radiation and chemotherapy. His initial PSA at diagnosis was 652. The chemo only gave him 6 months now his PSA is up to 23. Does anyone have any advice on future treatment? Our Dr. Only wants to do routine protocol bit he is only 59 years old, it's aggressive and we need to take a proactive aggressive approach. He is in good spirits and looks good physically but the rising PSA is of great concern. He has already tried alternative treatments on his own including the ketogenic diet. Any help or insight would be much appreciated as I am the only child and not ready to see my dad suffer as he does not deserve this and has much more to give in this life. Willing to look into any trisls, experimental treatments offered. Thanks!
