My husband has been diagnosed with bladder cancer and will be operated on in three weeks time. However, a close friend was diagnosed with a more advanced form 5 years ago, and after surgery and her bcg treatment it came back a year later. So she has had to have BCG treatment for three years in total, and now is on a yearly cystoscopy check up with no signs for the past year or two of anything. So we can say she is in remission. This treatment is very good.
