The link to a PDF file below is to an interesting booklet produced by European Genetic Alliances Network.  It answers questions about what Personalised healthcare is.

“In one sense , personalised healthcare is nothing new.  It is what doctors have aimed to provide for their patients through the exercise of their clinical judgement, backed up by specialist knowledge and the use of appropriate diagnostic procedures.

However, as research advances and we begin to understand more about he complexity of common disease, it is clear that a standard approach to the treatment of various  diseases and disorders does not yield the results patients need.  Increasingly therapies are now being selected based on an understanidng of the underlying genetic components of a condition and how these interact.”

The PDF link will tell you more.
