Any leukemia survivors out there? I survived childhood leukemia and was treated with Cytoxan (Cyclophosphamide). It’s been over 30 years, but it’s been proven that Cyclophosphamide causes Transitional Cell Carcinoma (TCC) of the bladder. I’m just curious if anyone has experienced this? I suffered from microscopic hematuria for 15 year that I know and never had it checked. I just recently diagnosed with Stage 2 - TCC with the presence of CIS.
