I have had visual blood in my urine for over a year. I have had a ct without contrast (normal) blood test everything is (normal), kidney function test (normal) liver function test (normal). urine evaluation rbc in urine but everything else (norma), cystostopy (normal). I am afraid that I have kidney cancer. I was wondering if the ct scan without contrast would show any tumors or if I have to get a ct scan with contrast in order for the tumor to show. The visible blood in the is not everytime i urinate probably1 time out of 20 and i never see blood in the morning after i wake up. I am not sure what to do I am afraid that I could be dying slow from something that has not been found. I would appricitate any advise I have been a nervious reck for over a year. I have stop all fun active activities because i notice the blood in the urine more after i have been active, it is very hard on me because i am an active person, will it hurt me to work out.
Thank you for your Help
