> Even though we know prognosis is much better for cancer, and many other diseases, if you catch it early
This is, to some extent, misleading.
I mean, earlier treatment is beneficial, but there's a significant confound. All else being equal, if a cancer is less aggressive and slowly growing it is more likely to be detected early.
Put in other terms, the cancers detected earlier by screening are a very different population of cancers detected late and with progression.
