Good Health Is In Your Future

Imagine a day when medications are custom-designed to be delivered at the right time and the right dose, based on your DNA and sophisticated diagnostic tests that will help doctors identify conditions like breast cancer and heart disease earlier - and possibly even prevent them.

These developments will be possible within the next two decades, thanks to researchers who catalogued the female X-chromosome last year and uncovered unexpected variations on how those genes behave.

These findings are expected to yield fresh insights into cancer, heart disease, autoimmune disorders and other illnesses that strike women. This means that scientists may be able to understand and predict what diseases individual women will get, what symptoms to watch out for and which treatments will be most effective.
