I would like to add that Aberaterone and Xtandiwere prescribed to lower my PSA. They are basically adt. Aberaterone kept PSA low for a while but not XTANDI. My oncologist ordered PSMA WHEN PSA stayed high, around 75.I had no reason to suspect wide spread bone Metastasis as there was no pain. I suggest you may want your oncologist to order PSMA sooner rather than later. Frankly, I was shocked. Scary.
