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.

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

Cohort Study

Human

2020 Oct

The study found that when people, especially those who had cancer before, were told about strange findings from their body scans, they were much more likely to get biopsies — even if most of those biopsies turned out to be harmless. This supports the idea that telling people about these findings leads to more medical testing.

Similar Assertions

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.

When doctors tell patients about unexpected lab results, it leads to 37% more biopsies—but even more biopsies happen when doctors share unexpected MRI results, meaning imaging scans seem to trigger more follow-up tests than blood tests.

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.
