Hi I have had 3 episodes of gross hematuria over the past 12 months, spaced out around 3-4 months. When the first episode occurred I was freaked out but after googling, I saw where it could have been the chemicals I used to clean my commode. So I wasn't concerned the second time it happened. The last time, I laughed about it to my mom and she made me tell my doctor. A urine dipstick over a 10 day period showed small to moderate levels of blood in my urine, and when my doctor spun that out further he saw "some" blood. Urine culture came back with no infection present and all other indicators on the urinalysis were within range. I have no pain, no symptoms other than extreme fatigue which started approximately around the time of the last gross hematuria. Is it possible to have episodes of gross hematuria so widely spaced and not have any other symptoms? Of course I am worried about cancer.
