Hello Jay1975.  Good on you for caring for your friend.  First of all I wouldl suggest that you ring MacMillan Cancer Support as they can advise you across the entire spectrum of what you will need.  They can also arrange to have it provided as you are not expected to lay out for things like hospital beds and other equipment.  They can also provide nursing care when needed.   I am attaching a link so you can get the phone number and see what they can do to help.   If your friend does not live in your area you will need to talk to your local GP if that is where you want his care to be centred.  Not knowing the financial situation you may need to talk to the Benefits people so he can get whatever assistance is needed.  I am sure I am forgetting loads of things but I think MacMillan will give you some help.  Oh, and make sure you tell the other people who care for your friend where he is now living when he comes to live with you.  Also, depending on his current home, there will be things to take care of there if he will not be returning.  Sorry to make such a terrible situation sound so matter-of-fact but I hope this helps.  Annie
