I have bladder cancer, and have been treated for almost three years now.  I went through BCG Immunotherapy, which proved ineffective as the variety of cancer is BCG resistant.  I have been undergoing chemotherapy using Valrubicin for almost two years, and while it seems to be working, the side effects are pretty miserable.  If the Valrubicin won't work, the next step will be bladder removal and life with a stoma and bag.
