How does personalized healthcare differ from what physicians have always provided: namely, tailoring their diagnoses and prescriptions to each patient? How is healthcare based on the capacity to acquire, store, and process data "personalized"? Isn't that just an ever more impersonal intensification of a technological approach? This book probes the tension between patient-centered care and an ultra-technological process that, in reducing individuals to molecular units, appeals primarily to the healthcare industry and authorities.
