Abstract

Precision medicine is revolutionizing the treatment landscape for breast cancer by shifting from a one-size-fits-all approach to tailored therapies that consider individual patient characteristics. This review explores the key components of precision medicine, including genomic profiling, biomarker identification, and pharmacogenomics, which allow for targeted treatments that optimize therapeutic efficacy while minimizing adverse effects. Advances in companion diagnostics and ongoing clinical trials are enhancing our understanding of how to best apply precision medicine in clinical practice. Despite these advancements, challenges such as access to genomic testing, cost, and data interpretation remain barriers to widespread implementation. Ultimately, precision medicine holds the potential to significantly improve outcomes for breast cancer patients, paving the way for more effective and personalized treatment strategies.
