About 25% of women older than 40 years have dense breast tissue, which makes it particularly difficult to distinguish between healthy and tumor tissue on a mammogram."We all know that mammography is not perfect," commented Eric Winder, MD, professor of medicine at the Dana Farber Cancer Institute, in Boston, Massachusetts. This new technique could be a useful adjunct, particularly in women with dense breasts. There is already increasing use of magnetic resonance imaging in such women, he noted, and this technique might offer an alternative."Strategies for breast cancer screening are becoming more individualized, and we are moving away from a 1-size-fits-all scenario," he commented at an ASCO press briefing that he moderated.
