 [ Symptoms ] i am under doctors care but i feel like i need a second opinion [ Disease ] well it is certainly possible for prostate cancer to spread to surrounding structures such as the bladder however i would not automatically jump to that conclusion as you know prostate cancer usually is slow growing and not usually aggressive there are other reasons why you could have red blood cells in your urine sample a urinary tract infection can cause this for example i would assume they tested your urine for bacteria when you gave the sample but maybe not also lab error could come into play i would recommend simply waiting to see what the urologist has to say i hope it turns out to be nothing serious take care
