3-D Mammography May Increase Cancer Detection Rates

Breast cancer screening using 3-D imaging may increase detection rates of breast cancer, The New York Times reports. The finding is based on a study in JAMA which looked at “454,850 screenings: 281,187 with digital mammography alone and 173,663 that combined it with tomosynthesis,” Tomosynthesis “is nearly identical to a routine mammogram, except that in mammography the machine is stationary, while in tomosynthesis it moves around the breast,” giving a 3-D image. The combination therapy detected more overall breast cancer, as well as more cases of invasive cancer. “Tomosynthesis uses more radiation than mammography alone, but the dose is still low and well within limits considered safe, doctors say.” It received FDA approval in 2011 but is not yet considered the standard of care for breast cancer screening.
