Cut through the noise. Focus on the evidence.

Health information is everywhere online. While much of it can be helpful, it is often over-simplified or taken out of context. When that happens, it becomes much harder to know what to trust.

Misinformation is already shaping real-life health decisions. For CPAW 2026, we’ll be sharing the latest research that highlights the scale of the challenge for healthcare professionals and the people they support.

When information is unclear or misleading, it can distract us from behaviours that science has proven to reduce cancer risk.

We believe you deserve clear, trustworthy information about your health – not content taken out of context and not claims that sound convincing but lack evidence.

That’s why we’re empowering people to look beyond the headlines, trends and quick fixes, and trust what the evidence really says – to choose science, not fiction.

At World Cancer Research Fund, our cancer prevention guidance is grounded in decades of global research into diet, weight, physical activity and cancer.

We bring together the best available evidence to help people make informed choices – without hype or false promises.

Because when it comes to cancer prevention, evidence saves lives.
