@parus, don't be disturbed about the prospect of having body parts removed. The BCG therapy doesn't go there. It involves putting a solution into the bladder, allowing it to remain for a period of time (minutes), then excreting it into a urinal or urine bag or pan. The solution includes modified bacteria that can kill superficial tumor cells on the lining of the bladder. It's been nearly 10 years since I was diagnosed with tumors in my bladder. They were removed in a TURP operation (TransUrethral Resection of Prostate tissue -- one in a hospital surgical suite, the other in a walk-in surgical center. About two weeks later I began the six-time BCG therapy. No pain or disability from any of the treatments. Just yesterday I had my annual cystoscope examination of my bladder lining; all is well, and I won't have another look for another year. We give a strong measure of the credit to the BCG treatments which seem to have prevented the outgrowth of new tumors. Martin
