I had esophageal cancer and survived. Now 17 years. It required radical surgery. But was more like stage 3. I dont think that is what he has because for someone like him would have had earlier detection as a result of more extensive regular physicals. It is preventable and treatable.
Same here, stage 4, diagnosed in April 2017, in hospice since December 2017 when it was determined surgery would have to be too radical, and hence ineffective.
It's not the end of the world, because none of us is destined to live forever in this time and place. God takes care of all, if one allows God to.
As for being indispensable, while Rush Limbaugh is certainly unique, no one is indispensable. Someone else will evolve to take his place.
A neighbor was diagnosed with 4th stage esophageal cancer and was gone in a year.
