The human body is a highly complex ecosystem made up mostly of microorganisms, otherwise known as bacteria. The National Institute of Health’s Microbiome Project estimates that bacterial cells outnumber human cells 10 to 1 in the human body. It’s therefore logical to question what role these microorganisms play in human disease and wellness.
Most research to date exploring possible links between our microbiota and specific diseases has focused on gut bacteria and links to diseases such as diabetes and multiple sclerosis or neurological conditions such as autism.
New research looks at the bacterial composition of breast tissue in breast cancer patients vs. healthy breast tissue.
The study uncovered significantly lower levels of a specific bacterium species in the breast tissue of women with breast cancer vs. those who did not have breast cancer. This raises the question as to what role, if any, these bacteria play in the development and growth of breast cancer.
