We don’t know yet if scanning the whole body with MRI helps healthy people live longer or save money over time when checking for cancer.

We don’t have enough long-term data to know if getting a full-body MRI scan when you feel fine actually helps people live longer or saves money — so doctors can’t say if it’s worth doing.

We don’t have enough solid proof yet to say that scanning the whole body with MRI helps healthy people find problems early or saves money.

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.

Using whole-body MRI to screen everyone for cancer isn't a good idea right now because it often misses cancers, finds too many harmless things that cause worry, isn't done the same way everywhere, and we don't know if it actually helps people live longer or healthier lives.

There's no universal rulebook for using full-body MRI scans to check healthy people for cancer, so different hospitals do it differently—making it hard to trust the results or use them widely in doctors' offices.
