I've seen the opposite - someone choose to step away from treatment because it wasn't worth it. It was a very, very hard decision. They faced a lot of pressure from others (who they loved) but they did it. Subsequently some of their friends even questioned the proberty of the people involved - the implication was that they shouldn't have died so easily, that there were things that could have been done. But this was a man in his late 70's, with two degenerative diseases and an advanced hard to treat cancer (on top of a long standing easy to treat managable one). So - it's always hard, one way or the other.
