I wonder about the differences between countries in what is done upon a questionable mammogram finding. I also wonder if different screening methods (digital mammo, MRI, PET) might be better.
I guess the underlying thought here is that it doesn't benefit survival if you catch a cancer before it's visible or palpable.
One of the things about studies like this..or rather the conclusions.. that concerns me is that it kind of assumes better treatments of today/tomorrow won't derive benefit from earlier detection though we don't have stats to know that. For instance, vaccines or immuno therapies seem to be an earlier the better therapy.
