In conjunction with the start of Breast Cancer Awareness Month, Hologic (NASDAQ:HOLX), medical imaging systems manufacturer, rang the opening bell Monday morning at NASDAQ as part of a media tour demonstrating their new 3D mammography technology.

In front of NASDAQ in the middle of Times Square Hologic had parked a mobile version of the new 3D system where they demonstrated the new technology.

Dr. Laurie Margolies, Chief of Breast Imaging at the Dubin Breast Center at Mount Sinai in Manhattan, says the technology marks a major shift in breast cancer screenings.

While a 3D breast scan is preferable, Dr. Margolies says the important thing is that women simply go get screened.
