I am into my 4th treatment, of six, BCG for bladder cancer. To make a long story short, she could not get the cath in this time, only about 2 inches. Hurt like hell, I even blead a little out of the cath. She called doc, they asked if I was peeing all right or had any other problems, no. They cancelled my treatment this time, being I was bleeding and they did not want the BCG getting into my bloodstream. She said (four years of doing this), that this never happened before. I am asking, what could have caused this and why would it be any better next week. If everything is coming out all right, why can't the cath go in? Do I need to be worried?
