While side effects sometimes are a good sign, some have those and still have recurrences. Also, over time, especially into maintenance regimens is where the cumulative effects often cause problems. As you have had 5 of your 1st course you are close to being done and the old cysto that will follow is the real test. Being early detection it is possible your TURB and what your URO did may have also destroyed the bad cells. Either burning and/or what is often used is a bladder wash of chemo to prevent re-seeding.
Glad you are able to play golf. I do too. Keep posting as you have questions.
DX 5/6/2008 TAG3 papillary tumor .5 CM in size. 2 TURBS followed by 6 instillations of BCG weekly with a second round of 6 after a 6 week wait.
57, have CIS, been through 2 TURBT, Induction, and numerous Maintenenace.
I had a pretty strong reaction during my 6 Induction, and since then - almost nothing. A slight fever here and there, but not bad. I wondered the same thing, and asked Urologist , she confirmed - doesn't mean anything to not have side effects (except lucky).

Repeat Induction BCG - Jan 2020 Complete
I'm 66 years old and have CIS with early diagnosis. I have a healthy immune system. Before I started BCG I read about all the possible side effects. I am now in week 5 and have had none of them. I even questioned my urologist and asked if no side effects equates to no immune response, and he said not to worry. I played 18 holes yesterday and frankly forgot I even had bladder cancer.
