Precision Medicine: What It Is and Why Your Genome Is the Key

Precision medicine is an approach to healthcare that tailors treatment to each individual's unique genetic profile. Instead of prescribing the same drug at the same dose to everyone with the same condition, precision medicine uses genomic data to identify which treatment will work best for each specific patient.

How it works in practice

Pharmacogenomics — the study of how genes affect drug response — is already changing how medications are prescribed. Some people metabolize certain drugs too quickly (making them ineffective), while others metabolize them too slowly (causing dangerous side effects). A simple genomic test can predict these responses before the first dose.

Cancer treatment is leading the way

Personalized cancer treatment is the most advanced application of precision medicine. Tumor sequencing identifies the specific mutations driving a patient's cancer, allowing doctors to select targeted therapies that attack those specific mutations rather than using broad chemotherapy that damages healthy cells too.

The genome as foundation

Every application of precision medicine starts with the same thing: the patient's genome. Having it pre-stored and ready means that any precision medicine application — from drug selection to cancer treatment to gene therapy — can begin immediately rather than waiting weeks for sequencing.
