Medical Screenings: How Checking for Illness Can Risk Your Health

Dr. John Reizer

If you’re like me, you have probably received a letter or a notification from your doctor or health insurance company telling you it is time for a routine health screening. They present these tests as a simple, risk-free way to stay healthy. However, many people are discovering a frustrating truth about modern healthcare: routine medical screenings frequently cause a chain reaction of false alarms, expensive bills, and unnecessary, painful procedures.

This cycle is so common that doctors actually have a name for it. They call it the “cascade of care.“ While these tests are allegedly not rigged to trick you, the way the medical system is set up often creates serious problems for perfectly healthy people.

The problem is that these screening tests are made to be incredibly sensitive. They’re like a home security system set to the highest possible setting. The system is so afraid of missing a burglar that it sounds the alarm every time a leaf blows past the window.

In medical speak, this is called a false positive. The test flags a problem that isn’t actually there, or it finds a tiny abnormality that would never have harmed you if left alone.

Once a screening test sounds the false alarm, it is very difficult to stop the momentum. A single abnormal result usually kicks off an onslaught of invasive and potentially dangerous procedures.

Even if your doctor thinks a test result is probably a false alarm, they feel legally forced to order more tests just to be safe. They’re afraid of lawsuits.

A simple blood test or scan can quickly lead to painful biopsies, exploratory surgeries, or strong medications. These follow-up procedures carry real risks, including infections, bleeding, and long recovery times.

The healthcare system is a money-making engine that runs on a “pay-per-service” model. Hospitals, labs, and clinics make money every single time they perform a scan, draw blood, or perform surgery. A false alarm is highly profitable for the medical industry but highly expensive for you.

Medical research shows that several standard screenings are notorious for causing false alarms.

Lung scans, for example, often find tiny spots in the lungs. Most of these spots are completely harmless scars from old colds. However, finding them often leads to invasive lung biopsies, which can cause the lungs to collapse.

Mammograms routinely flag tissue changes that are not dangerous. This often leads to highly stressful biopsies, radiation, or surgeries for anomalies that never would have made the patient sick.

PSA screenings for men return many false positives. A man’s PSA levels can jump just from sitting on a bicycle or having a minor, harmless inflammation. High numbers often lead to painful prostate biopsies that carry risks of permanent side effects like incontinence.

Remember, you do not have to agree to every test put in front of you unquestioningly. You have the right to ask questions and protect your own body. Before agreeing to a routine screening, ask your doctor what are the chances a false positive result is returned, what invasive procedures will follow if a positive test result is found, and what are the risks associated with the follow-up procedures.

Sometimes, the best medicine is no medicine!
