@gently They bring up a good point about these test regarding timing and it’s also true with scans; they are not effective during treatment that’s working. So if you’re on ADT and you’re still sensitive, neither will help identify your particulars. During an ADT vacation, you seem to have a unique opportunity to learn more.

Being educated prior to decisions is critical. Good doctors don’t expect blind trust.
