Precision medicine, also called personalized medicine, is an approach that uses information about a person's genes, proteins, and environment to prevent, diagnose, and treat cancer.
In oncology, precision medicine often relies on molecular profiling and genomic testing, such as next-generation sequencing (NGS), to identify specific alterations within a tumor. These findings can help guide treatment selection, including the use of targeted therapies matched to particular biomarkers.
The goal is to select treatments most likely to benefit an individual patient while reducing unnecessary exposure to therapies unlikely to work.
