Hello DanM1, 

It's so sad what is happening to your mum as she is suffering confusion and anger after being diagnosed with stage 4 lung cancer. It's good news that the cancer has shrunk and the chemotherapy seems to be effective but it seems like she is suffering from terrible confusion, anger and forgetfulness and this can be really hard for her loved ones who feel powerless and don't recognise her the way she used to be. It must be distressing to see her like this and being passed from one clinician to another and feeling like you are not getting any continuity of care must be a little unsettling too. I am sure you have done this already but it might be worth bringing up again when you see her specialist how confused and angry she seems to be at the moment and also the fact that she seems to be forgetting everything - insist you are concerned about this, that she isn't quite herself and ask whether this needs looking further into or investigating. 

I can imagine your sisters and you are feeling rather powerless at the moment and you mustn't just suffer alone and I hope that you can talk to your mum's medical team soon about what is going on so that they can help you find solutions or tell you more about the cause of this terrible confusion, forgetfulness and anger issues. You may find it helpful too to talk to one of our cancer nurses about this as they may have some good suggestions for you and you can reach them on this free number 0808 800 4040 Monday to Friday from 9am to 5pm (except Christmas day and bank holidays)

I hope that treatment continues to be a success in shrinking the cancer and that they will also manage to tackle these issues you mentioned so that your mum's mental wellbeing - as well as that of her loved ones - improves. 

Best wishes,
