Researchers find new approach to treat drug-resistant HER2-positive breast cancer

Resistance to therapy is a major problem in the cancer field. Even when a treatment initially works, the tumors often find ways around the therapy. Using human cell lines of the HER2-positive breast cancer subtype, researchers from the UNC School of Medicine and UNC Lineberger Comprehensive Cancer Center have detailed the surprising ways in which resistance manifests and how to defeat it before it happens. The discovery provides the experimental evidence for the potential development of a novel combination therapy for HER2-positive breast cancer. Read more here.
