I know what it means, but my doc said to me that I would not have got this far without it, so for me it has extended my life and my quality as well, my leg was just about to snap, potentially putting me in a wheelchair as it is I have a nail from the top of my thigh to my knee, the Ribociclib has given me hope and freedom. I am sorry to hear about your mum, I have lost my dad and my sister to cancer, my sister lived 6 weeks from diagnosis and my poor Dad was younger than I am now when he passed, so I understand your pain and frustration. I hope your mum is as comfortable as she can be.
