Healthy at Any Age

摘要

It's a cliche that we're living in the too much Information Age, and if you Google anything related to health, it's plain to see why. Plug in "breast cancer screening" and you'll get 7.39 million results, including guidelines from the National Cancer Institute, the U.S. Preventive Services Task Force, the American Cancer Society, the Centers for Disease Control, and the Mayo Clinic, all on the first page of links. There's also PubMed, where anyone can access 19 million scientific papers that otherwise might be confined to journals in the musty stacks of academic libraries.
