Winter,
Based on what I read here, and discussions with others in the bladder cancer group at the clinic, the high frequency "terrible side effect" from BCG reported by some sites on the internet seem rather questionable.
BCG is accepted as the primary treatment for superficial BC, and individuals do react differently. IF symptoms are or become terrible, get support from the care team. Drink LOTS of liquids afterward. Ask for pain meds if needed. Start AZO early.
Don't let the worst cases on the internet discourage BCG, (or other recommended therapy).
I lose 2 to 3 days to each BCG treatment - cramping, urgency, frequency, spasm, and a need to have a bathroom within 5 feet or less at all times. It might be compared to preparing for a colonoscopy, but extended to 2 or 3 days. Not a lot of fun,but doable.
I notice that the recent TURBT "came back negative, still T1 G3" ?? If negative , (no sign of disease) why is the staging still T1 ?? If there is no cancer showing, why not T0 ??
The internet is good for research, IF you stick to reputable sites such as major teaching hospitals and the National Institutes of Health published reports.
thanks for being there for your husband.
Best
Jack
