A single mammogram may seem quick, but consider this: across the globe last year, millions of people heard the words "you have cancer," and when—and how—their disease was detected would dramatically write their survival story, from a breast cancer diagnosis in the U.S. offering a 99% five-year survival rate if caught early, to a late-stage lung cancer diagnosis where those odds plummet to just 8%.
