In a world of health misinformation, the ability to judge a claim is protective — it spares you fear that is not warranted and choices that can do harm. Cancer attracts myths precisely because it is frightening; reliable information is the antidote.
Who published it? Look for hospitals, universities, health authorities and named experts. When was it updated? Cancer knowledge evolves — recent, dated sources are more trustworthy. Is it evidence-based? Reliable information cites research, not anecdotes or single stories. Does it sell something? Be cautious when a “fact” conveniently promotes a product or cure.
Miracle cures, secret knowledge “they” don’t want you to have, one cause for all cancers, a single food that cures or causes everything — these patterns almost always signal unreliable information, however sincere the person sharing them.
Check it against a trusted source, ask a professional, and — if you are not sure — simply don’t pass it on. Not sharing an unverified claim is a quiet act of public health.
