Uncertainty lies at the heart of modern medicine in ways that most physicians—not to mention their patients—often fail to recognize. Fundamental imperfections in our understanding of health and disease limit doctors' ability to combat illness. Hatch, an assistant professor of medicine at the University of Massachusetts Medical School, argues that physicians who ignore this uncertainty often overtreat their patients, resulting in sometimes harmful, even fatal consequences.
By the same token, far too many patients assume that more medical care is always better than less, thereby seeking or consenting to toxic treatments that trigger needless suffering. Hatch provides examples from such fields as breast cancer, cardiology and infectious disease. He also offers straightforward rules of thumb to help readers navigate medical advice.
It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
