Rising PSA

First diagnosed with aggressive cancer spread to the bones in 2019when my doctor missed appointments, and before I could see him nine months later, my PSA was at 131. Variousoral treatments, kept it down for a few years, with the help of Elgard. Four months ago I ended my first treatment with Pluvicto and my PSA was at .9. I’ve had no treatment in four months although my PSA has steadily been rising and now it has tripled since last month. It is at 61 last week. I am not scheduled for any doctors appointments until February 17. It is now aggressive and out of control again. Any suggestions? Yes, I have messages into my Oncologist.
