Precision medicine is an innovative healthcare approach that tailors treatment and prevention strategies to an individual’s genetic, environmental, and lifestyle factors. Unlike traditional medicine, which often follows a “one-size-fits-all” model, precision medicine considers variations in genes, proteins, and other biological markers to determine the most effective therapies. It improves treatment efficacy, minimizes side effects, and can predict disease risk more accurately. For example, in cancer care, genetic profiling of tumors allows doctors to select targeted therapies that are more likely to succeed. Precision medicine represents a shift toward personalized, data-driven healthcare for better patient outcomes.
