Sobrediagnosticado: enfermando a la gente en busca de la salud

What is Overdiagnosed about?

In modern medicine, early detection and preventive testing have become a cornerstone of public health. However, Dr. H. Gilbert Welch and his colleagues Lisa Schwartz and Steve Woloshin alert us to a growing phenomenon: overdiagnosis. This book, based on decades of research, exposes how the pursuit of health can lead to diagnosing diseases that would never have caused symptoms or affected quality of life. Through concrete examples, the authors show that overdiagnosis not only generates unnecessary anxiety but also leads to aggressive treatments with real side effects. The central message is provocative: sometimes, less medicine is better medicine.

What makes Overdiagnosed unique?

Unlike other books about the healthcare system, Overdiagnosed focuses exclusively on the harm caused by overdiagnosis. The authors not only criticize current practices but also offer a solid scientific basis for understanding when a test is truly necessary. The book is written in accessible language, aimed at both health professionals and patients. It includes real cases and statistical data that help contextualize the problem. In addition, the authors propose practical solutions, such as fostering conversation between doctor and patient about the risks and benefits of diagnostic tests.
