The targeted scans and tests that we already do offer surprising little benefit. Mammogram screening based on randomized-trial all-cause mortality, has not shown a measurable reduction in total deaths. Randomized colonoscopy screening has not shown a statistically significant all-cause mortality reduction. |

My grandfather went to the doctor complaining of chest pains, they gave him a colonoscopy, and he died of a heart attack a week later! Clearly colonoscopy doesn't reduce mortality!
There's no reason for almost any medical intervention to have a statistically significant effect on all cause mortality. That doesn't mean it doesn't have any effect on mortality of individuals.
