UNIONDALE - Long Island women are among the first in the nation to have access to the latest technology in the battle against breast cancer.

Nassau University Medical Center (NUMC) started using 3D mammograms last month. The new process, called tomosynthesis, takes X-ray images of the breast and allows doctors to scan through the images from top to bottom.

According to experts, one in about 10 women who have a mammography end up with a "false positive," but that tomosynthesis could eliminate that problem. NUMC's Director of Radiology, Dr. Victor Scarmato, says the process has already proven to be effective.

Good Samaritan Hospital in West Islip also has the new technology and is expected to start using it next month.
