Copley Hospital is excited to offer 3D mammography (breast tomosynthesis) for breast cancer screening. Breast tomosynthesis produces a three-dimensional view of the breast tissue that helps radiologists identify and characterize individual breast structures without the confusion of overlapping tissue.
According to research by the Journal of American Medical Association, breast cancer screening with tomosynthesis, when combined with a conventional 2D mammography, has a 40% higher invasive cancer detection rate than conventional 2D mammography alone. It also reduces the amount of call-backs or “false positives” which can cause anxiety, by up to 40%.
“Early detection is key in successful treatment and survival rates for breast cancer patients,” says Lise Hamel, Director of Diagnostic Imaging at Copley Hospital. “We believe this new technology, enabling us to see detail as never before possible, will help save lives. While all patients will benefit, we feel this is an especially valuable service for women receiving a baseline screening, those who have dense breast tissue and/or women with a personal history of breast cancer.”
The tomosynthesis screening experience is similar to a traditional mammogram. During a 3D Mammography exam, multiple, low-dose images of the breast are acquired at different angles. These images are then used to produce a series of one-millimeter thick slices that can be viewed as a 3D reconstruction of the breast.
Breast cancer is the 2nd leading cause of cancer death among women, exceeded only by lung cancer. The stage at which breast cancer is detected influences a woman’s chance of survival. If detected early, the five-year survival rate is almost 100%.The American Cancer Society recommends women age 40 and older should have a mammogram every year and continue to do so for as long as they are in good health.
