Yes, the past century has seen great progress in neutralizing infectious disease (though it is likely that the HIV epidemic itself was an "own goal" of basically iatrogenic origin [1]), but nearly everything else, including cancer, is a wash.

Unfortunately, a sober analysis of the benefits and harms of actors in the medical space cannot afford to give much credit for effort or good intentions.
