Mammography technology has improved over the last 20 years, offering better detail than older methods.

“we're reading pure digital now we have much better capacity to read even an x-ray than we did 20 years ago don't we we do and basically now what's actually happening is we're actually doing a fluoroscopic version of a mammogram we're basically sort of trying to slice through this 3-dimensional object and actually get the detail of it a three-dimensional layer whereas before the mammogram were typically just like the chest x-ray was done two different views compositing that three-dimensional picture together so that 3-dimensional view of the mammogram is actually better than it was now”
