- Description: An EWG newsletter promoting its report “Rethinking Carcinogens,” which draws on Halifax Project research suggesting that combinations of chemicals — including some not carcinogenic on their own — may cause cancer by disrupting several cancer-related pathways at once.

It’s time to rethink how we talk about cancer.

One in three Americans will be diagnosed with cancer, yet nearly*half* of all cancers are preventable.

Along with genetics, diet, lifestyle and viruses, exposures to toxic chemicals clearly contribute to this epidemic.

EWG’s latest analysis on the topic, [**“Rethinking Carcinogens,”**](http://action.ewg.org/salsa/track.jsp?v=2&c=NnqHOfOycKtClkEKmEHBXSJg%2Ft4wY8cs&ref=foodconsumer.org) takes a close look at new research on chemical exposures and cancer conducted by the Halifax Project, which involves hundreds of cancer researchers and scientists from around the globe.

The findings of the Halifax Project add to long overlooked evidence that combinations of chemicals may cause cancer.

**EWG’s report connects the dots between the Project’s findings and what we know about how human cells develop cancer to help you better understand which combinations may be the most dangerous and what chemicals to avoid altogether.**

This new research builds on the knowledge that cancer develops in many steps and not all at once. It suggests that exposures to certain combinations of chemicals – even ones that are not individually carcinogenic – may cause cancer by disrupting multiple cancer-related pathways in the body.

The Halifax Project’s investigation of the relationship between cancer and low-dose exposures to particular chemical mixtures may fundamentally shift the way we think about carcinogenesis.

Together, we’ll change the discussion and make cancer prevention a public health priority.

Sincerely,  
  
Ken Cook
