I am going to start Kadcyla post operation. I had 5% live cancer left after chemo, when they took it out. No cancer left and it hasn’t gone to my lymph nodes. I don’t know if I can take more chemo, the docetaxyl was awful. What are the side effects like with this? Do I lose my hair again? I might have to have 14 and it terrifies me if it is as hard as the docetaxyl.
