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.

The study found that when people got full-body MRI scans, lots of them got unnecessary biopsies for things that weren’t cancer, and very few actual cancers were found. This means the scans cause more harm and cost than benefit, supporting the claim.
Whole-body MRI for opportunistic cancer detection in asymptomatic individuals: a systematic review and meta-analysis.
This study looked at using full-body MRI scans to find cancer in healthy people and found it rarely finds cancer, causes lots of false alarms, and we don’t know if it actually saves lives or is worth the cost — which is exactly what the claim says.
This study found that whole-body MRI scans on healthy people often find weird things that need more tests, which matches part of the claim. But it didn’t check if the scans save lives or cost too much, so we can’t say for sure if the whole claim is true.

This study is still happening and hasn't shown yet whether whole-body MRI saves lives or costs too much — so we can't say if the claim is right or wrong.
Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
