Brain tumor found during preventive scan puts full-body MRIs back in the spotlight

A former Bachelor contestant's preventive scan detected a brain tumor before symptoms emerged, reigniting discussions about full-body MRI screenings. Celebrities like Kim Kardashian and Paris Hilton have endorsed such scans, though medical experts debate their benefits for healthy individuals. The scans, which can cost up to $2,500 and are typically not covered by insurance, aim to detect early signs of diseases like cancer but face scrutiny over clinical effectiveness.
