Our understanding of breast cancer is evolving as researchers study the behavior of invasive cells under a microscope, which could potentially lead to a dynamic cellular defense against the spreading of cancer beyond the breast tissue. The article, “How Cells Actively Stop Breast Cancer from Becoming Invasive” by Ana Sandoiu, appears on the website Medical News Today. Breast cancer is diagnosed as “invasive” when the cells lining the milk ducts spread to the surrounding tissue, allowing cancer to spread to other parts of the body. This form of breast cancer is more difficult to treat. “New research shows that the myoepithelial layer is not just a passive ‘fortress’ that may or may not be invaded by cancer cells. The myoepithelium actively tries to reach out and snatch the cancer cells that are trying to escape to the rest of the body,” the article reveals. The video below shows this process in action. Andrew Ewald, professor of cell biology at the Johns Hopkins University School of Medicine in Baltimore MD, led the study, with findings published in the Journal of Cell Biology. The bottom line: The findings could lead to individualized tumor behavior predictions based on the gene expression within the myoepithelial cells.
