The numbers are scary: The average woman has a 12 percent risk of developing breast cancer at some point in her life. For women with certain genetic mutations or risk factors, lifetime risk can climb to 85 percent.

Even more terrifying than the numbers, however, are the rumors; rumors that the contrast dye used in MRIs for breast cancer screenings is harmful; rumors that are driving women away from an adjunctive screening tool that could save their life.
