Don’t know why you were not treated with Salvage radiation/ADT when your PSA was consistent at 0.2; and then to let it rise continuously to its present level?!
Don’t want to be a sh** stirrer but your doc seems to have blown it. You still are very treatable but I would seriously consider having someone else treat you going forward. I would not trust this doc to be able to gauge success or failure at this point. Just my thoughts,
