My PSA jumped 41% from 0.95 ng/mL to 1.34 ng/mL, and, interestingly, my PSA doubling time went from 10.0 months to 11.5 months using the last five readings.

Needless to say, that was a larger increase than I expected, but I’m also not surprised or panicked about it.

I’ll gather my thoughts and send an email to the urologist to seek his/her guidance. I’ll mention the canceled and rescheduled appointment; ask for their thoughts about another PSMA PET scan (or other scan); and ask, “What’s next?”

Other than that, I really don’t know what else needs to be done in this limbo period of being between one treatment and the likely next treatment.

UPDATE, 06 September 2025:

Day 5,414 – Doctor Response

The urologist emailed late yesterday and didn’t want to dispense any guidance via email. He preferred to have the discussion in person (so do I), and he contacted the appointment schedulers to try to find something open in “early October.”

With luck, the schedulers will call early next week, and we’ll get something on the calendar.

More to come. Be well!
