Precision medicine is a healthcare approach that tailors treatments and prevention strategies to an individual's genetic, environmental, and lifestyle factors. By leveraging advances in genomics, biomarker analysis, and data-driven insights, precision medicine enables more accurate diagnoses and personalized therapies. This approach improves patient outcomes by optimizing treatments based on unique biological profiles rather than a one-size-fits-all model. Professionals in this field work across medical research, clinical practice, and biotechnology to develop targeted interventions that enhance efficacy and reduce adverse effects.
