A clarification is in order on BCG after hearing from @mayobruce and @spooz2. It was my understanding from the beginning after my bladder cancer was detected that BCG is a treatment aimed at killing cancer seeds that crop up on the lining of the bladder. It is not expected to delve deeper into the tissue and attack cancers that have begun their journey toward or into bladder muscle tissue, as I understand it. Recommendations against second or more BCG treatments are, in fact, a strong endorsement of its effectiveness in treating superficial tumors on the bladder lining. As good as it is for this, if it didn't fix the malignancies with a six-time series of treatments, the infection is almost certainly deeper and in need of a more strenuous therapy, so don't waste time trying it again. My positive BCG experience was conclusive evidence that my tumors were in their initial superficial stage, and my annual cystoscope examination earlier this week was clear years after my superficial cancers were discovered. Pleased as I am about my good fortune, I am sad to hear that BCG failed to fix your bladder and hope that, knowing that, your medical team will follow your instructions to take the next reasonable step to eliminate any malignancies that remain.
