You are welcome!
I'm very happy you stick to the positive thinking!
That's very important for your health.
You were diagnosed with a low grade, tumor confined to the inner lining of the bladder. Sometimes, low grade, Ta tumors, when are larger than 3 cm (you've mentioned the size, so, I guess it was a bigger tumor), poses risk of recurrence.
That's why the intrabladder chemo and surgery in those circumstances, aren't the complete treatment and BCG is added.
Why you are nervous about BCG treatments?
Have you started experiencing some side effects?
The great majority of people find BCG treatments tolerable with side effects being temporary, and some have no adverse reactions at all.
Thinking of you!
Best wishes!
