Hi Mnelson,
I see that your first urinalysis was fine, no blood was detected. Besides you had a ct scan 8 months ago that was fine, too. So if you have BC, it's likely at the early stage and treatable. I am wondering if they looked for cancer cells in the urine with blood. My BC was accidentally found on the ct scan for my other cancer. It was a small mass, but visible. If your scan was fine, the tumor could be non existent. Hopefully you don't have cancer, but in any case, you should stop smoking right away.
