I know I personally had a PSMA PET scan and it found a metastasis on my spine. I got it zapped three years ago, and I have been undetectable since.

I know so many people I can’t count how many that had PSMA PET scans that found metastasis that were zapped and most are doing just fine. Scholz believes strongly in Waiting for the PET scan to show metastasis and have them treated. He feels it is extending the lives of many people doing it that way instead of salvage radiation

I don’t think there’s any doubt that the PSMA PET scan has proved useful long-term for many people that have had metastasis found. Before that scan, there was no way to find them, though a CT scan was marginally helpful, It’s just not the same.

I know one guy had over 15 metastasis zapped and he’s still around at least a couple years after having it done. Normally, they do chemo for that, but he went for multiple SBRT sessions.

Proton radiation has been used for over 30 years. The guy that invented it had his prostate cancer treated decades ago with it. He lived to Over 100.. They’ve been doing that type of radiation on children for brain tumors.

I’m not so sure these particular techniques are unproven.
