I'm sorry to hear that.

I know it's very upsetting right now, but it's not dire: surgery sometimes (often?) doesn't get all the cancer, because there's no way to detect any individual cancer cells that might have already left the prostate but haven't built tumours big enough to show up on imaging.

If your new scans are still clear, it might just be a case of active surveillance for now. If imaging shows cancer still localised (or just a few metastases elsewhere), it might be easily treatable with radiation; you might also end up back on ADT, and maybe an ARSI (like the -lutamides), depending on what they find.

I hope the appointment goes well today. Best of luck!
