A cancer misinformation rapid-response unit that rebuts within 48 hours

A small team monitors social media and news for spreading cancer falsehoods and publishes clear, sourced rebuttals within two days, before the claim becomes established.

Public health agencies built infodemic units during COVID-19 but cancer has no equivalent. The proposal is a standing unit (hosted by a national cancer institute or charity) using social listening to detect fast-growing false claims about cancer causes, cures and treatments, producing plain rebuttals with primary sources within 48 hours, and distributing them through clinician networks, platforms and patient organisations. Impact is measured through claim spread trajectories and clinic reports.

Hypothesis
Rapid rebuttal reduces the reach of targeted false claims by at least a third compared with matched untreated claims, and reduces patient questions about those claims in clinic.
Rationale
Misinformation compounds with time; early, sourced counter-messaging from trusted voices is the best-evidenced countermeasure short of platform action.
What would test it
Run the unit for a year with claims randomised to rapid rebuttal or observation; compare spread metrics and clinic survey data.
