An Immense New Power to Heal: The Promise of Personalized Medicine

Is personalized medicine—what some scientists call genetic medicine—a pipe dream or a panacea? Francis Collins, current director of the National Institutes of Health and director of the Human Genome Project, considers this new era “the greatest revolution since Leonardo,” while Nobel Laureate Leland Hartwell compares personalized medicine to a train that has not yet left the station—“a very slow train with a very long way to go . . . before we arrive at our destination.”There is no denying that new technology, which has triggered an explosion of scientific information, is ushering in a revolution in medicine—for specialists, general practitioners and the public. Anyone can spit in a cup and, for a small fee, learn about his or her individual genetic make-up.
