Your body is host to 100 trillion or more microbes. That’s more than the human cells in your body. In fact, we now know you have more microbes in your body than there are stars in our Milky Way galaxy.
Since medical school, I’ve been fascinated by this ecosystem we carry around. But back then there was no name for it. Today, we call it the “microbiome.”
And now, exciting new research reveals that women with breast cancer had dramatically different microbes than women with benign breast disease. Women with cancer also had more microbes in their breasts. And the microbiome from cancer sites was significantly different from normal tissue just inches away in the same woman.
Mayo Clinic researchers used DNA sequencing to analyze breast tissue from 33 women. They identified striking differences in the breast bacteria of women with and without breast cancer. They found that the inside of your breast is a complex microbial world. And it’s much different from the skin tissue just outside your breast.
