Language and rhetoric aside for a moment. Isn’t the premise of even curing cancer a flawed one at best? I’ve heard (and I’m no doctor), that theoretically cancer is the disease that takes us after we’ve cured everything else, that the body will either succumb from dementia (mental) or cancer (physical) because our aging and depleting cells are no longer capable of fending off disease.
So yes, it would make sense to me that we (as a society) should focus on cancer as a thing worth understanding and coping with rather than on conquering or battling it. But there’s the macro and the micro. And if it treating it like a disease worth conquering produces the psychological will for an individual to cope with it and perhaps overcome it, then they should do what feels right for them.
