Need for BCG

Diagnosed 5 months ago and have had three TURBT. First pathology was invasive of the bladder lining and the second was not. Urologist had me on the "wait list' for BCG. When it became available, I was called in for a cystoscopy and another tumor was found. After that 3rd TURBT, the urologist indicated there was still no BCG, but because of the progression of the 3rd tumor, I wouldn't need BCG anyway. Does this ring true or make sense for BCG to be called for, and then not?
