After 2 TURB and 12 BCG treatments, a cysto showed two red areas, not near the original cancer sites. A biopsy was done; the pathology was "Acute and Chronic Cystitis". The urologic oncologist said it was caused by the BCG treatments. At the next cysto exam, about 3 months later, no inflammed areas were seen. It has been 14 months since this happened. All cysto exams have been good.
