Precision medicine is an innovative approach to medical treatment that takes into account individual differences in people’s genes, environments, and lifestyles. The promise of precision medicine is delivering the right treatments, at the right time, to the right person. It provides medical professionals the resources they need to target the specific treatments of the illnesses that patients may encounter. Although the term “precision medicine” is relatively new, the concept has been a part of healthcare for many years. For example, a person who needs a blood transfusion is not given blood from a randomly selected donor; instead, the donor’s blood type is matched to the recipient to reduce the risk of complications.
