Hi, my nan was diagnosed with lung cancer 6 months ago. They couldn't diagnose what stage she was at because she is so frail. The past 4 days she hasn't eaten and has had very little fluid (a couple of sips a day). She is sleeping 90% of the time and her breathing has changed. We know she is near the end but unsure on how quick it will happen. Does anyone know how long it usually takes at this stage, thank you.
