Hello I hope you don't mind me posting, I'm so very worried.

My mum was diagnosed with ovarian cancer 2 years ago, which she had chemo and it kept things at bay. She has recently had a scan which showed something in her bile duct, so she has started chemo again. She had it a week ago and has been much more ill than when she had it before. She also has jaundice and itching and I'm worried sick. Could this be because the chemo is attacking the tumour... or because it's too late?
