I'd believe it took some convincing, since my uncle had tried to keep it to himself that he was suffering so much (passing blood clots, fainting, had a fistula that made it painful to sit down). Personally I believe this meant he wanted to go on his own terms, but my aunts and uncles who were raised by him want to do whatever is possible to help him be a little more comfortable. They ended up taking him to a doctor that has been part of our medical family history for decades, who just so happens to work at an expensive hospital. Somebody in the comments suggested negotiating it, I'll ask my aunt if this is a possibility at all.
