June 2, 2023 – Last month, journalist and actor Maria Menounos advised People that she’d been recognized with pancreatic most cancers after having a full-body MRI scan.
The scan had detected a 1.5-inch mass on her pancreas after CT scans and different testing couldn’t discover an issue. A biopsy confirmed the mass was a stage II pancreatic neuroendocrine tumor. In February, she had surgical procedure to take away the most cancers, a part of her pancreas, her spleen, and 17 lymph nodes.
“I want individuals to know there are locations they’ll go to catch issues early,” Menounos, 44, who was recognized with a mind tumor in 2017 and kind 1 diabetes final summer season, advised People. “You cannot let worry get in the best way. I had that second the place I believed I used to be a goner – however I’m OK as a result of I caught this early sufficient.”
Now, Menounos’s mission is to persuade insurance coverage corporations to cowl whole-body MRI scans for everybody. But medical organizations, in addition to specialists in oncology, radiology, and well being psychology, say the proof doesn’t but show these imaging procedures can provide individuals the peace of thoughts they need or the knowledge they should stop well being points.
“We do suppose a world wherein screening is customized and adaptable over time is an aspirational objective. At this time, there are particular imaging screening suggestions for people with particular inherited, genetic mutations corresponding to BRCA2,” stated William Dahut, MD, chief scientific officer for the American Cancer Society, referring to a mutation identified to trigger breast most cancers. “This is completely different, nonetheless, from a full-body MRI scan.”
MRIs sometimes concentrate on one organ or space of the physique and require referrals from certified medical professionals. But now, non-public corporations, per your request and for a hefty worth, will scan your total physique, even for those who don’t have signs or considerations.

The drawback is that full-body scans carry a danger of false-positive findings that may result in pointless and doubtlessly invasive follow-up testing and procedures that aren’t solely costly, but additionally anxiety-inducing, stated Christopher Hess, MD, chair of the Department of Radiology and Biomedical Imaging on the University of California, San Francisco.
The chance a whole-body MRI finds a critical situation that’s treatable is way decrease than your danger of dying in a automobile accident (1 in 93 individuals over their lifetime, based on the National Safety Council), drowning whereas swimming (1 in 1,006 individuals), or being critically injured from falling down stairs (37.8 per 10,000 individuals within the United States), Hess stated. Plus, the problems these scans typically uncover are usually on the “spectrum of regular” that sometimes don’t require remedy, corresponding to small mind aneurysms.
Additional testing with CT scans and positron emission tomography (PET) can even expose individuals to radiation which will raise their risk of cancer later in life, the American Academy of Family Physicians stated in a press release that discouraged using whole-body scans for early most cancers detection in individuals who do not have signs. Some procedures might trigger problems as effectively, Hess stated. For instance, a biopsy of a small kidney lesion, which usually wouldn’t want testing, might trigger inner bleeding.
The American College of Radiology additionally opposes the follow. “To date, there is no documented evidence that whole physique screening is cost-efficient or efficient in prolonging life” in individuals with no signs, danger elements, or household historical past of illness, the group stated in a press release posted in April. The FDA launched an identical assertion in 2017 relating to full-body CT scans, saying no evidence indicates such procedures provide “more benefit than harm.”
Experts agree that Menounos’s case is the uncommon exception to the rule. Although CT scans and different testing appeared regular, she saved having extreme stomach ache and diarrhea. The additional imaging she sought “was actually logical and because it seems mandatory,” Dahut stated, though an MRI of simply her stomach would have sufficed. Still, early-stage pancreatic cancers can often be difficult to find on routine scans.
Researchers have estimated that tumor detection is less than 2% in individuals with out signs who get a whole-body MRI. But using the scans as a preventive well being measure is evolving, stated Resten Imaoka, MD, a musculoskeletal radiologist on the Washington University School of Medicine in St. Louis.
A 2021 research revealed within the European Journal of Radiology discovered that one-third of 576 whole-body MRIs confirmed “clinically relevant findings,” 2.6% of which had been cancers. Imaoka says these numbers are “significantly increased” than these of previous analysis, suggesting that the scans might be used with different screening strategies for individuals with out signs. (The research additionally discovered that 16 individuals studied – 2.8% – had false-negative findings – scans that didn’t at first reveal trigger for concern – 5 of which proved to be most cancers.)
Whole-body MRIs could be useful and even most popular in sure circumstances, Imaoka stated. People who’ve Li-Fraumeni syndrome – a uncommon genetic dysfunction that makes individuals extra more likely to have many alternative cancers – could profit from the scans as a result of their total our bodies are threatened by illness. These scans are additionally useful in detecting multiple myeloma, however not a lot for the early detection of colon, pores and skin, breast, thyroid, lung, and most different cancers, Hess stated.
Blood-based checks could also be a extra helpful most cancers screening device for the typical individual, Hess and Dahut stated, as a result of they’re simpler to carry out than MRIs. Several have already been approved by the FDA, though most are used together with different screening procedures like mammograms and colonoscopies.
If you’re wholesome and discover you possibly can’t cease occupied with the possibility of being sick – placing you within the class of the “frightened effectively” – in search of procedures like whole-body MRIs could solely deliver short-term aid, and perhaps extra stress, stated Natalie Dattilo, PhD, a medical psychologist and psychology teacher at Harvard Medical School in Boston.
“It would not repair the foundation of the issue. In remedy, you’re employed to construct a better tolerance for uncertainty, get extra comfy with the unknown and doubtlessly disagreeable, whereas gaining confidence in your skill to deal with something, even a critical sickness,” she stated. “Fear stems not from the dreaded factor itself, though it could actually actually be upsetting, however from the worry of not figuring out, or the uncertainty and unpredictability of it.”
