My Primary Care Physician just told me that on 12/27/2012 I had 1+ mg/dl blood in my urine.  On 3/18/13 I submitted another urine sample and it is now 2+.  I was not aware there was any problems in December.  He now wants to do a CT scan, possible cystoscopy and see a uriologist.  Of course, I am worried sick.  He asked if there was any bladder cancer in my family.  I have lots of cancer in my family but no history of bladder cancer.  I feel great! What percentage of patients with 2+ have bladder cancer?  Thanks,
Hi and welcome to Chat Doctor. Thank you for your query. Very little. Blood in urine can be sign of cancer, but this is the last thing to think of. It is probably some reinfection, ureteral stone or urethral micron jury. You should do tests your doctor mentioned just to be sure, but I dot think there is a reason to be worried if you don't have any other symptom. Wish you good health.
