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.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
A study that I posted on my blog a couple of months ago showed that cancer cells are very good at devouring the mitochondria of healthy cells around them as basically as a source of fuel. That is a type of autophagy. Unfortunately, they're consuming the the normal healthy tissue as well.
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.
