Unhealthy gut sets stage for breast cancer spread
t's a key question scientists have long sought to answer -- why does breast cancer metastasize or spread in some women, but not others? A new study suggests part of the answer may be hidden not in the breast itself, but in the gut. Inside our stomach and intestines are a collection of microorganisms known as the gut microbiome. The mix can be healthy or unhealthy, and new research finds, that could impact the risk from breast cancer.
