You might also ask for a decipher test, I found that interesting. Didn't like results, but good to know. Also, I had some genetic testing. One thing I might mention and pretty sure I am right, if you have radiation treatment first, they most likely would not do surgery at a later date. From what I understand, very few places do surgery after radiation.
When you get the PSMA PET I found it interesting to get the SUV reference scores for parotid glands, liver and blood. Then compare that to your prostate score. That helped me understand the prostate score better. I had to really ask a lot before they would give me these reference organ scores. Uptake > blood but less than liver is a low score 1. Greater than liver but less than parotid gland intermediate score 2. Uptake greater than parotid is high score 3.
Anyway, I wanted this information and found it useful, but sure had to ask a lot before they gave it to me. Others on here know much more than me, so they might give you much better advise.
