I wonder if the advent of PSMA scans will be a relevant factor in how hospitals use the ultra sensitive PSA tests. My oncologist was going to get a choline pet scan but said with a PSA of 0.023 it was probably not going to show anything. If PSMA scans can be reliably shown to be picking things up at lower levels, and if they were more available, maybe then the ultra sensitive scan would lead to earlier identification of cancerous cells. So, in summary, without the PSMA scan, the ultra sensitive PSA levels were not telling the full story. I think it takes both. And, was I 'lucky' in that my PSMA scan picked things up? Others with higher PSA levels than me have had scans which showed nothing.
