I would like to know if I have prostate cancer. I have taken an immunology test. Came out positive for anti streptolysin. I have had an MRI which showed some enlargement of the prostate gland and said possible explanation is prostatitis. My psa levels after doing 6 rials were as following; 17,13,14,16,56,25,19. The day it was 56 I had extreme fever and pain all over. The Doctor wants to perform an biopsy but I want to know if the psa levels are high due to the prostatitis and or infection or is it cancer. Thanks.
