bcg

My boyfriend has chronic lymphocytic leukemia and I was worried about the same thing. My doctor was a little unsure. I googled and found a website for the Leukemia Association...they have a place where you can email such questions. Answered me within a
day. Turns out that it will not cause problems in the case of CLL.
In fact, there were clinical trials using BCG to treat CLL....it was not effective, but none of the patients had reactions.
