Hi, Depends on the scale. Mostly 90 is about 20 times the upper limit of normal. This could be cancer and it could be anything else that irritates or destroys the prostate such as stone, infection, blockage. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Matt Wachsman, Addiction Medicine Specialist
