Waiting to locate where my newest PSA readings are coming from. Had radical prostatectomy PSA returned immediately- had salvage radiation in the pelvic region with Lupron within three months, my PSA is back. it’s more than tripled in the last month- going in for the PSMA pet scan this month to see where it’s coming from. I need to learn more about these exotic drugs even while hoping I won’t have to take them…PSA is still under 1.
