ggg, in some ways the hardest thing is knowing that there is very little that you can do as the spouse to do anything to help survival. It is the most awful feeling.
Regarding the awful stats.....dh always says that in the end, when you get down to an n of 1 stats don't realy mean that much, you are either OK or you are not. You could be one of the unlucky 5% in a cancer group where 95% are going to be OK. This though has always helped him with his diagnoses whereas I run around like a headless chicken, accessing the internet and scaring myself witless with 'what ifs'.
And they are giving him chaemo, whic means that the medics don't think that he is boyond hope. these drugs cost! And the time of the doctors. If they think there is no point , they don't treat.
I hope that things go well for them both.
