Hello... my mum has st.4 gallbladder cancer. She has had one round of chemo that hasn't worked. They want her to have a more aggressive chemo drug that she isn't sure she wants. 
I've called a cancer centre this morning about immunotherapy. They have confirmed she could have it for her type of cancer. Does anyone have any information about it? I'm assuming it's not something you can have on the NHS as they've not even mentioned it to her.
