Preventative Medicine
Catching problems before they become emergencies
The shift from treating illness to preventing it. Advanced diagnostics, regular screening, and early detection technology that can catch disease years before symptoms appear.
Why It Matters
Most of modern medicine treats crises. But the real gains come from prevention — and technology is finally making serious prevention accessible. Full-body MRI scans, continuous glucose monitors for non-diabetics, liquid biopsies for early cancer detection. These tools exist today, but the medical system doesn't yet routinely offer them. Knowing what's available — and knowing how to interpret results — can add years to your life.
Questions I'm Exploring
"Is a full-body MRI worth the cost and the false-positive anxiety?"
"Should healthy people use continuous glucose monitors?"
"How effective are at-home cancer screening tests really?"
"When does preventative medicine become hypochondria?"
Companies & Technology I'm Tracking
Prenuvo
CautiousDevice
Full-body MRI screening in under an hour, marketed as a preventative scan.
Key point: Genuinely detects some serious conditions early, but the false-positive rate creates real harm
Grail (Galleri Test)
WatchingDevice
Blood test claiming to detect 50+ cancers before symptoms appear.
Key point: Promising early detection technology; still proving itself in large studies
