Husband has just been told he has biochemical reoccurrence

Hi ,I had similar experience

A pet PSMA is unlikely to show any distant metastasis as its about a 30 per cent chance of seeing anything  until you reach PSA of 0.5.

Salvage RT would be my suggestion with 70 Gray spread over 8 weeks.

The cancer has not necessarily escaped at 0,20 PSA 

How long before the level was reached and what was the immediate post OP PSA?

Did you do ultrasensitive test?

How long till 0.20 was reached?

at 0.20 the only real possible cure is salvage radiation   (read this book PROSTATE CANCER RETURNS: How to Fight to Save Your Life When You Have a Biochemical Recurrence After a Radical Prostatectomy by Ronald Munson)

The pelvic bed where prostate used to be should be given RT as the cancer cells may still be local.

there is also a possibility that some prostate cells are still active.

But at 0.20 one needs to act

all the best

Good luck

Hi Ang1404, have a read at my profile. He should now have MRI and PET scans to try and target salvage radiotherapy which will likely be spread to cover the prostate bed as well. 
It’s a scary time, try to get as much information as you can. Wishing you both all best wishes,

Hi Ang1404. Sounds identical to me. Hopefully the scan will show in the bed then radiotherapy could still cure. Check my profile
