My Mum has lung cancer and was given just weeks to live a few months ago. She’s remarkably still here now, although it sucks that she’s suffering so much. Since December when she was at her worst she has improved slightly as in she has become slightly more mobile and is now on less oxygen but over the last week or so she’s been a lot more tired. I guess Ive been fearing the worse for months and every slight thing that gets worse I panic. What are the last stages of life? Will I know when the end is near? Thanks.
