What is the difference between precision medicine and personalized medicine? What about pharmacogenomics?

There is a lot of overlap between the terms “precision medicine” and “personalized medicine.” According to the National Research Council, “personalized medicine” is an older term with a meaning similar to “precision medicine.” However, there was concern that the word “personalized” could be misinterpreted to imply that treatments and preventions are being developed uniquely for each individual; in precision medicine, the focus is on identifying which approaches will be effective for which patients based on genetic, environmental, and lifestyle factors. The Council therefore preferred the term “precision medicine” to “personalized medicine.” However, some people still use the two terms interchangeably.

Pharmacogenomics is a part of precision medicine. Pharmacogenomics is the study of how genes affect a person’s response to particular drugs. This relatively new field combines pharmacology (the science of drugs) and genomics (the study of genes and their functions) to develop effective, safe medications and doses that will be tailored to variations in a person’s genes.
