Hi Carol,
I had same diagnosis as you in 2006, and am still here and life is good. I had a series if mytomycin treatments, and have to say the side effects, whilst definitely not unbearable lasted for about 12 months( a day or two not good , but mild cistitis like effects for much longer).The most time I had to take off work was the afternoons of the treatment. Don·t worry about the " catheter part" of bcg treatment- the amount of the liquid they put in your bladder is very small, and a tiny,tiny tube is used to put it in. Side effects vary from person to person, but for me, so far have not been too bad.Good luck on the 24th, with the start of your treatment, and feel free to bend our ears whenever you fel like it!
