With a GG1, what exactly do you mean by “high volume?” What numbers/findings indicate that?
(With a localized GG1, I was on active surveillance until GG1 increased to GG2; a 2nd opinion indicated GG3. Then 28 sessions of proton radiation + 6 months of Eligard.)
Normally, PSMA PET scans outperform all previous types of PET scan. However, ~15% of prostate cancers are PSMA-negative/naive. When PSA rises but can’t find it in the PSMA Pet scan, option is to do an Axumin PET scan or a Choline C11 PET scan. (May want to do this pre-treatment to find those “seeds” that may have already spread.)
