Hi Gina!!!
You are about the same age as me when I was Dx'd in 2006. I wasn't perimenopausal and I wasn't menopausal up until that time, and then menopause happened REAL QUICK and then it was over, all at the same time as Dx. At least, the menopause part was really easy....
Usually, the first BCG is pretty benign. It isn't until later when you will know if you will have side effects. For me, about the 4th treatment, I began to realize that for me, BCG was not going to be a picnic.
Just to lend credence to what your nurse told you, some will breeze through BCG and some will not have such a good time at all.
Hang in there and try not to worry. I am 2 years and 3 months past Dx with no recurrance. If you have a bad time with treatment , come here and talk it out with us. We will understand!!!
Please keep us posted as to how it goes....
Best regards,
Rosemary
