Hi Kitty2024 Sorry to hear about your mum.  It's tough with so many unknowns and everyone is different.  My beautiful mum died from brain cancer (primary) back in 2008 when she was aged 49 years.  She went into hospice care for the last 10 weeks.  Towards the end she was sleeping most of the time.  She couldn't get out bed and hardly opened her eyes. I do recall the hospice called me to come in because her breathing changed suddenly.  She was breathing really rapidly.  I knew it was time then so I stayed with her until she passed away which was around 4am after over 24 hours of very fast breathing. She was given morphine which slowed her breathing right down and then she just stopped breathing.  You may find this website helpful as it lists the symptoms for end stage. I recall looking for similar information at the time. https://www.brainhospice.org/brain-cancer-hospice-symptom-timeline   ... View more
