"Study Finds HER2-positive Breast Cancer Invades Organs Due To Fatal Chemical Attraction"
"Researchers at The University of Texas M. D. Anderson Cancer Center have solved the mystery of why an aggressive form of HER2-positive breast cancer travels readily to a few key organs - lungs, liver and bone - where it then establishes new tumors."
The research shows that metastatic HER2 BC cells have too many CXCR4 receptors and, as a result, tend to migrate to certain organs that produce an attracting substance. Efforts are underway to produce a drug that will block CXCR4.
