This is my line of work. Depends on how your area works. Where I am if a PSA (blood test) is raised, GP will refer via 2ww to urology, and the patient will have an urgent MRI prostate to see if anything clinically significant. Depending upon that report, a targeted biopsy will then take place.
This is the recommended way to do things, but some areas don't seem to have the MRI capacity, so biopsies are being done 'blind' which isn't great.
