When I was 5cystoscopys3 I had blood in my urine, not traces but pure blood first came out. My PSA was 1.7 and so my doctor disregarded Prostate Cancer - most doctors believe if your PSA is less than 4.0 you can't have cancer. For 3 years this went on and even my uroligist let it pass. I had back pain also - another sign of PC. When the bleeding was enough to half fill a urine sample with blood my uroligist finally did a cystoscopy (he said I may have Bladder Cancer - he was wrong and I was right - I had voiced concerns about Prostate problems. We did a biopsy and the cancer was found - more than 3 years after obvious signs were apparent. Be your own advocate and demand answers or switch doctors. If your PSA jumps more than 0.9 in a year it is a warning sign of PC. It does not matter what the numbers are - mine never got above 3.7 and a friend was at only 2.5 and he also had cancer. You know there is a problem - seek the answer and do not let them push it aside.
