Genomic medicine represents a paradigm shift from one-size-fits-all treatment to precision care tailored to individual genetic profiles. By analyzing a patient's DNA, doctors can predict drug responses, identify disease risks, and customize treatment plans.

Pharmacogenomics, the study of how genes affect drug response, is already changing how medications are prescribed. Certain genetic variants can make standard drug doses ineffective or even dangerous for some patients, while others may require different medications altogether.

As genomic testing becomes more affordable and accessible, it's moving from research labs into clinical practice. This shift promises to reduce adverse drug reactions, improve treatment efficacy, and ultimately deliver better patient outcomes through truly personalized medicine.
