Hi, I'm looking after my 69 year old friend who started immunotherapy treatment for lung cancer and had 2 sessions before becoming ill with side effects. A third treatment took place four weeks ago but nothing since due to being very poorly. My friend feels she has no quality of life now, usually a busy energetic person she has barely got out of bed for 6 weeks. Consultant is saying carry on but I don't think it's the right thing now. Does anyone have a similar experience to help me with please?

thank you
