For decades, surgeons have removed organs and tissues under the banner of prevention, including appendixes, tonsils, gallbladders, and even sections of intestines, often before clear medical necessity was proven. Many of these decisions were shaped by old beliefs, rushed diagnostics, or healthcare systems that rewarded procedure over patience. Today, medicine is quietly reckoning with that legacy.
The appendix, long dismissed as a useless remnant of evolution, is one of the most common casualties of this mindset. Millions have had it removed as a “precaution,” especially in the mid-20th century when abdominal pain was automatically treated as appendicitis. Yet research now shows the appendix serves as a reservoir for beneficial gut bacteria, helping to repopulate the microbiome after illness. Its removal can subtly weaken immune balance, increasing vulnerability to infection and inflammatory bowel conditions later in life.
Tonsillectomies tell a similar story. In the 1950s through the 1980s, removing tonsils was almost a childhood rite of passage in many Western countries. The reasoning was simple: prevent throat infections before they start. What was missed, however, was the tonsils’ role as frontline defenders, trapping bacteria and viruses entering through the mouth and nose. Modern studies suggest children who keep their tonsils may develop fewer respiratory and allergic issues as adults.
While both procedures can still be life-saving when infection or rupture is imminent, the pendulum has swung too far in the past. Some estimates suggest that up to half of appendectomies and tonsillectomies performed in certain decades were unnecessary or could have been avoided with better diagnostic tools.
The deeper issue is not just surgical judgment, it is culture. The medical field has often rewarded intervention, equating action with care. Patients too have been conditioned to believe that removing something is always safer than leaving it. It takes humility, both medical and personal, to pause before cutting.
Medicine is learning to ask harder questions now. Could inflammation resolve naturally? Can antibiotics or watchful waiting be enough? Each organ, no matter how small, carries purpose, often one we only recognize once it is gone.
