What's the deal with full body scans?

This week, Emily and Perry debate full body scans: MRIs that scan your entire body like a giant humming hammer in search of nails. Will it find something wrong with you? (Yes.) Will it be something you should be worried about? (Almost always no.) But what if that one time it's the one thing that ends up saving your life? (Yeah, this is actually kind of complicated.) Plus: a totally not shocking flu outbreak amongst our troops, fantastic news about the HPV vaccine and cervical cancer, and RIP blue and brown M&Ms. Submit a question for our weekly mailbag at wellnessactually.fm.See omnystudio.com/listener for privacy information.
