Tony Snow comes to mind.
God, I miss him.
But Tony was "famous"; there are many others whom nobody but their family and friends know, who go through the same horrible thing! :-(
People have died from different kinds of cancers for millennia and sadly, there's still NO cure for most of them.
I still miss Tony also. I still remember crying the morning the news came that he had died....and the surprise I felt at shedding tears for someone I had never met. He was a wonderful man.
