Given Cologuard (a non-invasive test for colon cancer) and the positive harm that any invasive medical procedure can cause, this study should strongly push us away from colonoscopies.  Someone should formulate a joke about how the benefits of being a rationalist include not getting a colonoscopy.

For those of us who are not familiar with colonoscopies, how much of an effect did people previously think colonoscopy screening had on mortality, and was the study well-powered to detect that effect?

Trying to make the headline is

Probably drop "is" or replace with "be".
