In march 2012 I finished radiation for prostate cancer. in the last year I have urinated blood just one urination and it was gone. Three days ago I urinated very dark blood with clots, lasted about 12 hours then clear again. Where does this blood come from and what is the cause?
Thanks for asking in Chat Doctor forum It is from the urinary tract/ejaculatory apparatus including prostate. It may be due to surgery /radiation over there. Consult your treating doctor for more information or else give details of any surgery if present. Good luck.
