Two weeks ago I had a bladder biopsy to check for cancer in something found during a recent cystoscopy, I had prostate and bladder cancer in 2001. The results were negative for cancer this time. Blood in the urine continues to be a concern for me. Pradaxa and amiodarone are two prescriptions taken daily for A-fib.
Thanks for your question on Chat Doctor. In my opinion you should get done PET SCAN to rule out positive uptake (hot spot) in bladder and prostate, as you had prostate and bladder cancer in the past. Biopsy may be false negative if sufficient tissue was not biopsied or biopsy taken from non-cancerous part of the lesion. So better to check this by PET scan and guided biopsy from the hot spot on scan. If still no cancer in biopsy report than urinary tract infection should be the cause. Better to get done urine microscopic examination and urine culture. Also look for malignant cells in urine.
