I can see why no one is in a rush to do a second biopsy. All your numbers are "on the fence." Slowly rising PSA could be age-related/BPH. PSA Density of .15-.20 is normalish. % free PSA is borderline.
Second TRUS-guided biopsies usually don't find anything. There's a possibility of some cancer in places that can't be reached by even the best DRE or TRUS-guided biopsy. You would have to use an mpMRI-guided biopsy, a CDUS-guided biopsy, or a saturation biopsy to find any there. The probability of an anterior tumor is higher if you are African-American.
You can have a PCA3 test (it's a urine test following prostate massage) that your insurance should cover because you've had a negative biopsy. All the other potentially useful biochemical tests would be fairly expensive for you or only available within a clinical trial.
Another approach you can discuss with your doctor is to take Avodart or Proscar and see what it does to your PSA. If it drops (average 50%) and stays down, that's a good sign. If it drops and then rises or if it never drops, then one of those fancy biopsies may be a good idea.
