Effect of Ivermectin on Time to Resolution of Symptoms Among Adults With Mild COVID-19
Association Between Patient Activation & Health Care Utilization After Thoracic & Abdominal Surgery
Are Early Detection & Treatment Always Best ? – By Robert H. Shmerling, MD Senior Faculty Editor, Harvard Health Publishing
Throughout my medical career, I’ve heard statements like these:
Early detection offers the best chance of cure.
If you wait for symptoms, you’ve waited too long.
Knowledge is power, and the sooner you have the information, the better.
Over time, I’ve realized they are often untrue. Many health conditions go away on their own. In such cases, early testing may amount to wasted effort, time, and medical cost. Some testing is invasive and has a significant risk of complications. And minor abnormalities may lead to more testing. There’s also the anxiety of waiting for results, or learning you have an abnormality of uncertain importance that requires additional evaluation.
