I would go and see a urologist based if it were based upon my experience. I had experienced seeing blood in urine when I was taking a baby aspirin to reduce incidents of heart attack. The test for infection was negative but when I had third time seeing blood urine, I went to ER and luckily, the ER doctor after confirming the blood in urine arranged CT scan with contrast. The CT scan showed a 2cmx1cm mass. The radiologist expressed his concern about the mass. I was wishing that the mass was just clot of my blood. A week later, the urologist did cystoscopy and showed me a coral like mass and told me that I had a bladder cancer. I am aware now that one of hall marks of cancer is its ability to have our body build new blood vessels to feed oxygen and nutrition to enable cancer cells to divide constantly. But because those new blood vessels are fragile, the constriction and the expansion of the bladder to store urine and void it, those blood vessels tend to break, causing bleeding. At that time, I thought perhaps, taking baby aspirin as blood thinner to reduce the risk of heart attack might have contributed in causing bleeding. I will never know. But, in anyway, finding that the mass was a tumor was shock to me but I am glad that bleeding had happened and I was able to see blood in urine and followed though the processes.
