One would think one is the evolution from the other!?..I did not see reference as to this test, in the post I put Up,( which was a re structure of another posters post as to lend clarification ) whether it was from trans-mural, ultrasonic guided tissue biopsy or from cellular debris passed from the prostate into the urine!...Both being...in general "Prostatic diagnostics" ....
A new , less invasive technique via urine analysis would be most welcomed!!....And may carry much greater prophylactic implications!...fwiw
Not sure what the original Poster had intended!!
