Understanding Esophageal Cancer

10. The Role of the Microbiome

The microbes found in the mouth are collectively known as the oral microbiota. The microbiome refers to the genes contained in the microrganisms that make up the microbiota. According to recent studies, oral microbiome imbalances associated with periodontal disease may also be implicated in the development of cancers. In one study of esophageal cancer patients, the presence of the bacteria that causes periodontal disease was linked with a lower survival rate in these patients. Other research points to the human microbiome as a possible indicator of cancer risk.
