Did you know?

True. Precision medicine (also called personalized medicine) in oncology represents a paradigm shift away from a 'one-size-fits-all' approach. It involves using diagnostic tests (often molecular) to identify specific biomarkers in a patient's tumor—such as genetic mutations, protein expression, or other molecular features—that can predict response to particular targeted therapies or immunotherapies. The goal is to select the treatment most likely to benefit the individual patient while sparing them from ineffective treatments and their side effects. Examples include using trastuzumab for HER2+ breast cancer or EGFR inhibitors for EGFR-mutant lung cancer.
