About a year before I was diagnosed I noticed some reddish colored blood in my urine - what also seemed to be pieces of blood (i now know as clots)
I did some research back then and determined that it just must be a kidney Stone and that I was lucky not to experience any pain as I've heard many tell of there kidney stone experiences. I was very wrong!
It all went away and I let it go... The blood came back almost exactly a year later. I thought, no big deal, been through this before, However, this second time it didn't go away. It just got worse. I didn't want to tell my wife, but I wasn't sure how what was going on. This time, I was honestly scared. Something was very wrong - I set up an appointment with my Primary Dr. He ordered lab work. In the mean time all visible signs of blood went away. I almost cancelled my lab work, but decided to go anyway and learned that there was blood in urine (just not visible to the eye)
My primary Dr ordered a CT scan to look at my kidney. Which seemed OK. He's the one that recommended I see a urologist. It took a couple of weeks to get it to see the urologist, in the meantime, the blood came and went. Sometimes very bad, when I did finally see him, He performed a cystoscopy which he knew right away it was cancer - Two weeks later - I was in for the TURBT, Pathology confirmed the cancer.
Sorry, probably to much information.
