This is why I'm asking, around here. So far, all of the rabbit holes I've been down, all say < 0.01, or < 0.02. There is nothing that says it is okay for it to be 0.911, except the surgeon. I'm in Spain, socialized healthcare where the doctors here are accountants before they are doctors.
I just ordered another PSA from an independent clinic UniLab in Barcelona. If the result is less, doubled, or the same, I will consult a private doctor for a second opinion.
