Colorectal cancer is one of the most common cancers and cancer deaths worldwide and its rates are increasing in many countries around the world, especially in younger adults. Emerging evidence points to a role of certain gut microbes in the progression of colorectal cancer by acting as toxins to gut cells. On the other hand, other microbes have been identified as potentially protective against colorectal cancer. In this episode of Biomes, Dr. Ruairi Robertson speaks with Prof. Wendy Garrett of Harvard University. Prof. Garrett is a leading doctor and researcher in the field of the colorectal cancer and the gut microbiome. Her work has shown exciting links between microbes originating in the mouth and how they may contribute to cancer when they travel down to the gut. Prof. Garrett discusses this research and future potential of targeting the gut microbiome as an adjunctive therapy for colorectal cancer. Microbiome Insights has partnered with some of World's leading cancer research institutes, helping researchers incorporate microbiome sequencing and analysis to their clinical studies.
