Personalised medicine was defined by European Union as
Providing the right treatment to the right patient, at the right dose at the right time.
The new vision of medicine known as precision medicine is an emerging approach for disease treatment and prevention that takes into account individual variability in genes, environment, and lifestyle for each person. It means that every patient can benefit from the scientific and technological innovations in the field of genomics. The challenge of precision medicine is to combine the molecular and clinical information of a single patient with the relevant biomedical knowledge in a way that yields practical application.
