I Have Had 3 Prostate Biopsises In The Past 7

I have had 3 prostate biopsises in the past 7 yrs, all neg, but a history of high PSA that indicates a 68% chance of prostate cancer, in the future. I am 62. I recently had blood in ejaculate, like after biopsy, my last biopsy was 2-3 yrs ago. My urologist was not overly concerned at this weeks annual. What do you think?
