As you know, this high PSA may be related to the prostate cancer (but prostatitis and benign prostate hyperplasia can also rise it). So urologist would do following;
1) A digital rectal examination (DRE); physical examination of the prostate
2) Trans rectal ultrasound (TRUS)
3) A prostate biopsy.

PSA 35 is not extremely high and can occur due to prostatitis (prostate infection). Prostatitis can be confirmed by prostate examination (DRE); as it shows tenderness. A biopsy is required for the other condition with high PSA. All the investigations can be done at a clinic.
