Most physicians are not focused on, or really even interested in, eradicating human disease. Alleviate suffering is more on the right track, but even if human disease were eradicated there would be much suffering that would be beyond any physician's control.
I'm sorry if you have to come up with this for an application or some sort of assignment. There is an unfortunate drive in the Twitter era to summarize, analogize, "distill" everything into the simplest possible terms and then act like it's an achievement to neuter complex ideas and ignore nuance. I think it leads to the modern tendency to see everything dogmatically, in black and white, and be supremely intolerant of the slightest hint of opposition.
