A gene expression test can help prevent unnecessary chemotherapy in breast cancer patients, yet its use in the Netherlands remains limited. This is shown by new research from the Netherlands Comprehensive Cancer Centre (IKNL), led by Sabine Siesling, principal investigator at IKNL and professor at the University of Twente.
