I can't read the whole thread as it is very close to home so I apologise if I repeat what others have said. I nursed my 18 year old son through his long fight with cancer. He died in a hospice last year aged 18. I have just nursed and lost my mum through her short fight with cancer a month ago. She died in hospital.
Hopefully after the MDT meeting you may have a rough timeline. With this in mind On a practical level you need to have lots of discussions with your brother with regards to his end of life care. Would he like, if possible, to see the end days at home or would he like to go to a hospice? If he wants to stay at home will he require a medical bed? Does he have a downstairs room that could be turned into a bedroom? Does he have a downstairs bathroom? May he need a stair lift to help him? He will be given a palliative care nurse who should be able to help and advise you on the above.
Does he need to see a solicitor to put his affairs in order. I know that sounds strange but lots of people worry about leaving things in a mess. Would he like to talk to you about funeral arrangements. These are desperately hard discussions to be had but they will undoubtedly be going through his head and you can help share that burden with him. Are you his next of kin? You need to establish who is so that you can make any necessary decisions on his behalf.
At home get lots of easy food in that dies not require much preparation. If he is able to eat then get in treats that he likes.
Prepare a folder that all his medical notes can go into, emergency numbers, appointments so that everything is in one place and easy to put your hands on.
Talk to him about how much care he wants from you/you are able to give him. He might not wNt you to help him bathing, for instance, but maybe ok to help get him dressed. If you can have an honest conversation then it does make it easier for you to help and for him to accept your help.
Talk, talk, talk. Laugh and cry with him. Share memories, say everything you want to say to him.
During the last few days with both my son and my mum we wanted them to be surrounded by love and laughter. We wanted them to hear and experience laughter right to the end. My mum loved her radio so we had it playing all the time for her. When sings came on we knew she loved we would sing along to them.
My son was an intellect and some of his teachers came in to see him in the last few days to talk normal school boy subjects with him. He also loved his food and was able to eat and enjoy food right up to two days before he died. He ate all the things he loved - treacle sponge pudding, chocolate cake, pasta. Through most of his treatment he couldn't eat so this was something he could enjoy at the end.
Look upon this as an honour - to look after a loved one at the end of their life. It will see you through some terrible times to know you did what you could for him.
Crying now so will stop. I hope that your brother is able to receive treatment that gives him time but is also gentle on him.
