Gut bacteria can drive colon cancer development

Gut microbes may reveal who is at risk for colon cancer, a study in mice suggests.
Scientists knew that people with colon cancer had different gut microbes than healthy individuals. But it was unclear whether the microbes changed in response to cancer or whether the bacteria drove the tumor development.
In the new study, researchers transferred gut microbes from a mouse with colon tumors into bacteria-free mice. Those mice developed twice as many tumors as mice that received healthy gut microbe...
