Why getting a full-body scan might lead to unnecessary needles
The effects of incidental findings from whole-body MRI on the frequency of biopsies and detected malignancies or benign conditions in a general population cohort study

When people got full-body MRI scans in a study, doctors told them about weird spots they found—even if those spots were probably harmless. This made people get more biopsies, but most of those biopsies didn’t find cancer.
Surprising Findings
People with prior cancer history had a 2.89-fold increase in biopsies after disclosure—far higher than the general population.
You’d think cancer survivors would be more cautious, but this shows disclosure triggers *over*-testing even in high-risk groups, not smarter care.
Practical Takeaways
If you’re offered a free or paid full-body MRI, ask: 'Will they tell me about every tiny spot? And what happens if they do?'

Getting a full-body MRI scan to check for problems isn't worth the cost because it often finds harmless things that cause stress and tests, and no one has proven it helps people live longer.
When people who’ve had cancer before are told about unexpected health findings from a research study, they’re almost three times more likely to get a biopsy — suggesting that sharing these findings might lead to more testing in people already at higher risk.
When people are told about unexpected findings from a full-body MRI scan, they’re much more likely to get unnecessary biopsies that turn out to be harmless — meaning doctors might be doing too many tests that don’t find cancer.
When doctors tell patients about unexpected findings on a full-body MRI scan, it leads to over three times more biopsies that find cancer—but even then, very few actual cancers are found, so it might not be worth the hassle and cost.
When people get full-body scans or lab tests and are told about unexpected results—even if those results might not mean anything—they end up getting more biopsies, especially when the scan findings are shared. This might lead to too many medical tests that aren’t really needed.
