My brother of 63 has been diagnosed with cancer. Today we have learned they can do no more and he hasn't got long left. I already lost my children's dad to the same disease at age 50 and my partners dad. 

I feel in despair really. Why has my kind hearted hard working and wonderful dad got this. He has worked hard all his life - too hard really just to give his loving wife and family everything they need. Why and how has this happened.  I looked after him when he was small and we are close. Cannot comprehend this.
