Illinois requires insurance companies to cover routine mammograms, but that doesn't necessarily include a new method of detecting breast cancer.
A mammogram is a low-dose of x-rays doctors use to spot breast cancer. An important tool, to be sure, but one that can result in false-positives.
Dr. Sarah Friedewald says that'll happen a lot less if women also get a 3D mammogram. Likewise, she says, the new technology makes it easier to spot abnormalities.
