PSMA PET/CT scans.

[Stevegr]

No.1 scan showed 2 spots. After Radiation second scan negative but PSA rising from .15 to .7 over 6 months. How many can I have in a year? Other accurate scan alternatives?

[Tall_Allen]

It is not important to identify all metastases large enough and PSMA-avid enough to show up on a PSMA PET scan. Metastases will always proliferate and grow.

[Stevegr in reply to Tall_Allen]

is having many scan a year harmful

[Tall_Allen in reply to Stevegr]

Yes. It’s a lot of unnecessary radiation.

Therapeutic IMRT radiation treatment involves about 1000 times higher dose _per_ session of a diagnostic scan. For those of us that have had 20 or more IMRT sessions, the incremental risk of a diagnostic scan is negligible. SBRT is a form of RT that has even higher doses. Once we have RT most long term SE's are baked-in so to speak.

Well said Derf4223. I can only add a Greek proverbial expression that will help Stevegr better comprehend what you already wrote: "Σιγά μην φοβηθεί ο βρεγμένος την βροχή".

Just had to translate that (love a challenge).

Don't let the wet be afraid of the rain.

Great proverb!
