Hi Sue58,
Saddened to read that your and he are here with your current situation.
In my, very fortunately, limited experience of cancer and, even more fortunately, limited experience of the latter stages I do to know what stage you are both at and what can be done to help you.
But, I do know that if you get the right help and support, Macmillan and or palliative care, they will know what will likely or probably happen and when, and may be able to give you a time. We none of us want to know when we will die, but almost perversely, it is the first question we want answered, when will I die, how much time do I have left? Well, it was with me.
My ex wife died from pancreatic cancer. She had Macmillan in attendance and they predicted to within an hour each way when she would pass away. And they were right.
If you want a "time", speak to a Macmillan or similar. Doctors and there like seem never to comitt to a time, maybe the are scared of getting sued, maybe they are told not to tell?
All I do know is that you should get all the help you can to help you both.
