The Claim
In asymptomatic adults undergoing whole-body MRI screening, ONCO-RADS categories 4 and 5 are associated with cancer prevalence rates of 42.9% and 75%, respectively, indicating that higher ONCO-RADS categories strongly correlate with increased likelihood of malignancy.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When healthy adults get a full-body MRI scan, those flagged with higher ONCO-RADS scores (4 or 5) are much more likely to actually have cancer—about 4 in 10 for score 4 and 3 in 4 for score 5.

What the research says
1 studyThis study checked MRI scans of healthy people and found that when radiologists thought a scan looked very likely or almost certain to be cancer (categories 4 and 5), it actually was cancer 43% and 75% of the time — exactly as the claim says.
