My husband was also in Vietnam 68/69 and has been battling bladder cancer since 2002. He has never smoked in his life. In the Army, he was in a Chemical and Biological Warfare unit, but carried water to hospitals in Vietnam. In 2003 he had the bladder removed and replaced with a neo-bladder. The cancer has since gone to the bone and within the last couple of months, it has eaten away the bone in his hip. He has gone from working a full time job in Nov. to not being able to walk with the aid of a walker, all in the space of a couple of months. He has had BCG x2, radiation, and is starting a second round of chemo. He was also found to have Prostate cancer, which was removed during the bladder surgery. Sandy
