Breast Cancer May be Spread in an Unhealthy Gut.

 

A new study at the University of Virginia reported in medicalxpress.com concluded that an unhealthy gut promotes the spread of breast cancer more quickly to other parts of the body by making the cancer cells more aggressive and invasive. Researchers found that disrupting the microbiome of mice caused hormone receptor-positive breast cancer cells to become more aggressive and spread. Researchers said that predicting whether hormone receptive-positive breast cancers will metastasize or not is affected by a variety of factors. “One of them is having a high level of immune cells called macrophages present within the tissue.” She continued “There have also been studies that have demonstrated that increased amounts of structural protein collagen in the tissue and tumor also lead to increased breast cancer metastasis.” Researchers concluded that having an unhealthy microbiome before breast cancer increases both and their effect is powerful and sustained.
Although the researchers used antibiotics to disturb the mice’s natural gut bacteria they emphasis antibiotics are not dangerous and should not be avoided by women, if needed, and more research is needed to establish if there is a link between chronic antibiotic use and cancer outcome. It is hope that as a result of this research doctors can manipulate the microbiome to benefit patients with breast cancer. Some things that may be useful include “A healthy diet, high in fiber, along with exercise, sleep—all of those things that contribute to positive overall health.”
