Question Before You Test: Why Full-Body Scans May Do More Harm Than Good
Unnecessary testing can lead to serious complications; one documented case resulted in emergency bypass surgery and heart transplant from an unneeded cardiac scan.
tortured by the results of tests they didn't need
Mark
So Lori Baute got a full-body scan and found lesions on her pancreas. That sounds like the scan did exactly what it was supposed to do—catch something early.
Mimi
It found something, yes. But what it found turned out to be benign cysts. She spent a week terrified of pancreatic cancer before a follow-up scan showed there was nothing to worry about.
Luke
Right, but here's the thing—we don't actually know if that week of terror was avoidable. If she hadn't gotten the first scan, she wouldn't have known about the cysts at all. So the question isn't whether the scan found something; it's whether finding it made her healthier.
Mimi
That's exactly why Redberg is pushing back. The major medical organizations—American Cancer Society, American College of Radiology—they don't recommend these scans for people without very high cancer risk. There's no evidence they save lives for average patients.
Mark
But couldn't they catch cancer early in some cases? Early detection is usually better, right?
Luke
In theory, yes. But the cascade problem is real. One test leads to another, and another. And some of those follow-up tests are invasive. The article mentions a woman who got an unnecessary cardiac scan, which led to an artery being torn during a follow-up procedure, which led to emergency bypass surgery and eventually a heart transplant.
Mimi
That's the worst-case scenario, but it's documented. And it started with a scan ordered just to reassure the patient, not because she had symptoms.
Mark
So the message is just don't get tested?
Mimi
No. The message is ask questions first. What will you actually learn? How will it change your treatment? Could you get healthier without the test? If your doctor can't answer those clearly, that's a red flag.
Luke
And if insurance doesn't cover it, that's another signal. Insurance companies require evidence that a test actually helps patients. Most of these direct-to-consumer scans aren't covered.
Mark
Baute said she plans to keep getting annual scans of her pancreas. Is she making a mistake?
Mimi
She's made a choice. She says the cost and anxiety are worth it to feel in control. That's her calculation. But Redberg would say she's now locked into years of monitoring something that was never a threat.
Luke
The honest answer is we don't know what Baute's outcome will be. We know she's anxious and she's spending money. We don't know if the scans will ever catch something that matters.

- Consumer-marketed full-body scans are spreading rapidly, fueled by fear and the seductive promise of catching illness before it strikes — but major medical organizations have withheld their endorsement for average-risk patients.
- Every test carries a hidden ledger: radiation that can itself cause cancer, procedures that can tear arteries, and a psychological toll measured in sleepless nights and cascading uncertainty.
- The 'diagnostic cascade' is medicine's quiet danger — one scan begets another, and another, until a woman who walked in with muscular chest pain walks out years later having survived a heart transplant she should never have needed.
- Patients are caught between the instinct to know everything and the clinical reality that more information does not always mean better outcomes or longer lives.
- Advocates like cardiologist Rita Redberg are urging patients to ask harder questions before consenting — what will this test change, and could a walk, a better diet, or a frank conversation with a doctor accomplish the same thing?
In an age when technology promises to illuminate every shadow within the body, the question of whether to look is not always answered by the ability to see. Across North America and beyond, patients are increasingly drawn to full-body scans and consumer health tests marketed as a form of vigilance, yet the major medical bodies that govern standards of care urge restraint — not out of indifference, but because every test opens a door that may lead somewhere no one intended to go. The story of medical testing is, at its heart, a story about the difference between information and wisdom, and the quiet courage it takes to ask whether knowing more will truly make us safer.
Lori Baute, 59, had always been skeptical of full-body MRI scans — the kind she associated with celebrities and excess. But with a family history of cancer, aging dependents in her care, and a close friend newly diagnosed with bladder cancer, she booked an appointment at a clinic near her Florida home. The results unsettled her immediately: lesions on her pancreas. Days of fear followed before a targeted follow-up scan confirmed they were benign cysts. The relief was genuine, but so was the anxiety she had absorbed along the way.
Baute's experience has become increasingly common as companies market comprehensive scans directly to consumers, framing them as proactive health insurance. Yet the American Cancer Society, the American College of Radiology, and other leading bodies do not recommend these scans for people without elevated risk for specific conditions. The caution is not arbitrary — it reflects a hard-won understanding that medical tests carry costs that extend well beyond their price tags.
Those costs are layered and serious. CT scans deliver radiation that, according to NIH estimates, will cause cancer in a small fraction of those scanned each year. Biopsies and endoscopies risk infection, tissue damage, and anesthetic complications. And there is the psychological weight: the waiting, the ambiguous findings, the years of follow-up monitoring that can follow a single inconclusive result. Cardiologist Rita Redberg of UC San Francisco describes patients who are 'tortured' by findings from tests they never needed — trapped in cycles of surveillance for anomalies that may never cause harm.
The most sobering illustration of this dynamic is a 2011 case documented in JAMA Internal Medicine. A 52-year-old woman with low cardiac risk and likely muscular chest pain received a precautionary heart scan. That scan triggered a second procedure. During it, her artery was torn. Emergency bypass surgery followed. Complications mounted. She ultimately required a heart transplant — a catastrophic outcome born entirely from a test ordered for reassurance rather than clinical necessity.
Redberg advises patients to ask three questions before consenting to any test: What will this actually reveal? How will it change my treatment? Could lifestyle changes alone address the concern? She also notes that insurance coverage offers a practical signal — tests endorsed by bodies like the US Preventive Services Task Force are covered precisely because evidence supports their benefit. Tests marketed directly to consumers, with no such endorsement and no coverage, deserve a harder look before anyone agrees to step inside the machine.
Lori Baute was skeptical when she first heard about full-body MRI scans. The idea seemed like something for celebrities and the very wealthy—she remembered hearing that Kim Kardashian had gotten one. But at 59, with a family history of cancer and the weight of caring for her aging mother and her adult brother with special needs, Baute found herself thinking differently about her long-term health. When a close friend received a diagnosis of bladder cancer, she made a decision. She booked an appointment at a clinic near her home in Ocala, Florida, that offered these comprehensive scans.
A week after her scan, Baute received results that shook her. The radiologist had found lesions on her pancreas. The word "pancreatic" flooded her mind with fear. She brought the images to her gastroenterologist, who ordered a more targeted MRI to investigate further. That follow-up scan revealed what she had hoped to hear: the lesions were benign cysts, nothing more. The relief was real, but so was the anxiety she had lived through in the days between tests.
Baute's journey is no longer unusual. Companies are increasingly marketing full-body scans directly to consumers as a tool for early disease detection, positioning them as a form of health insurance against the unknown. But the major medical organizations that set standards for care—the American Cancer Society, the American College of Radiology, and others—do not recommend these scans for people without very high risk factors for specific cancers. The same caution applies to many other medical screenings that doctors themselves recommend. Before saying yes to any test, there are things a patient needs to understand.
Every medical test carries a price tag that extends far beyond the bill. There is the time it takes, the cost of the procedure itself—some full-body scans and at-home blood screening kits run several thousand ringgit and are not covered by insurance—and the physical risks that come with the territory. A CT scan exposes a person to radiation, and according to estimates from the National Institutes of Health, a small percentage of people who receive these scans each year will develop cancer as a direct result of that radiation exposure. A biopsy or endoscopy might seem routine, but they carry the possibility of pain, infection, tissue tearing, reactions to anesthesia, or complications that spiral into something far more serious. And then there is the psychological cost: the anxiety of waiting for results, the stress of inconclusive findings, the weight of knowing something is there but not knowing what it means.
Rita Redberg, a cardiologist and professor at the University of California-San Francisco who has become an advocate for restraint in medical testing, sees the toll this takes. "I see patients every week in my office who are tortured by the results of tests that they really didn't need to ever have," she said. When a cyst appears on a scan, the patient enters a different kind of prison—years of follow-up testing to determine whether the finding is harmless or dangerous. Redberg advises patients to resist testing unless they have specific symptoms that warrant investigation.
One of the most troubling aspects of medical testing is what doctors call the "diagnostic cascade"—the way one test leads to another, and another, each one carrying its own risks. Baute herself plans to monitor her pancreas with annual scans going forward, accepting both the financial burden and the ongoing anxiety as the price of feeling in control of her health. But Redberg points to a documented case from 2011, published in JAMA Internal Medicine, that illustrates how far this cascade can go. A 52-year-old woman developed chest pain after starting an exercise program. Her doctor's examination suggested the pain was muscular and that her risk for heart disease was low. Yet the doctor ordered a cardiac scan anyway, to reassure her. That scan led to another test. During that second procedure, her artery was torn. She required emergency bypass surgery. Complications followed. In the end, she needed a heart transplant—all because of a scan that was never necessary in the first place.
Before agreeing to any test, Redberg recommends asking hard questions: What will this test actually tell me? How will it change the way my doctor treats me? Could I improve my health without this test? In her field of cardiology, she has found that many test results simply point patients back to what they already know they should do—eat well, exercise, stop smoking. Those recommendations need no scan to justify them. Insurance coverage itself can serve as a guide. If a test is covered by insurance, it has likely been vetted against scientific evidence and found to offer real benefit to patients. In the United States, insurers are required to cover preventive screenings that have earned an A or B rating from the US Preventive Services Task Force. Many tests marketed directly to consumers carry no such endorsement and no insurance coverage. That absence is worth paying attention to.
