I did experience blood in my urine before I was diagnosed. I had passed kidney stones in the past and I thought I had mused passed a stone. However, after discussing the blood in the urine with my kidney doctor, and rheumatologist they suggested a CT scan just to see if I did indeed have kidney stones. From the results of the scan, I did have a stones day also a tumor in my bladder. I was referred to an amazing Urologist and he performed my first cystoscopy. It was determined then I had a 2.5cm tumor and one month later I went in for a TURBT.
