The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.

Whole-body MRI screening in healthy adults produces more incidentaloma harm than cancer-mortality benefit.
Starting colonoscopy screening at 45 (vs 50) prevents enough early-onset cancers to justify the population cost.
Multi-cancer liquid-biopsy tests like Galleri detect early cancers at a stage that meaningfully improves survival.
