Precision medicine, also known as personalized medicine, combines genomics, big data analytics, and population health to create a new frontier in healthcare. It's one of the most promising techniques to cope with disorders for which there are no effective medicines or cures. Precision medicine is the customization of medical treatment to each patient's individual traits. It does not technically imply the development of patient-specific medications or medical devices, but rather the ability to divide people into subpopulations based on their susceptibility to a certain disease...or their response to a particular treatment. Genetics, pharmacogenetics, personalized medicine, and pharmacogenomics are all terms that have been used to describe the study of genetic variants and their impact on how people respond to medicines or therapies.
