I was recently diagnosed with stage 1 bladder cancer and I am being considered to enter drug trials at Mayo clinic in Scottsdale AZ. Part of the routine is BCG treatments and I am anxious about this process especially catheter insertion which I find very very painful. I wonder how other men tolerate this procedure? Note that I am not sure if this is the right place to post this concern so please direct me to wherever the appropriate blog is located in this forum.
