Was diagnosed with I.C. 30 years ago. I’m a 56 year old female. Have had Hematuria and pressure, burning intermittent throughout the years. 2.5 years ago had gross Hematuria and had CT immediately after and Cysto 1 month later. Both were normal. Had not had any gross Hematuria since. Had some burning over the weekend and then gross Hematuria on Monday. Put on Cipro and bleeding stopped by afternoon. Sent urine for culture but not back yet. Had cysto today and it showed red inflammation throughout bladder. Urine was normal. Dr said to be on the safe side will biopsy next week. Should I be concerned about cancer or will cystitis or I.C. cause that? Thanks!
