(Dense Breast Tomosynthesis/ Ultrasound Screening Trial)
Dense breast tissue, which is common, and normal (seen in about 40% of women screened), can mask detection of breast cancer on mammography. Ultrasound is known to improve invasive cancer detection after standard mammography in women with dense breasts. Tomosynthesis (3D mammography) improves cancer detection compared to standard mammography. It is not known whether ultrasound would still be of benefit or not after tomosynthesis in women with dense breasts.
Opened in December 2015, the purpose of this study is to determine the added cancer detection yield (if any) when screening ultrasound is added to 3D mammography in women with dense breasts. Women will undergo three annual rounds of screening. The study will accrue 6200 women aged 40-75 at Weinstein Imaging Associates and University of Pittsburgh Medical Center and is expected to complete accrual in March 2018.
If interested, please contact one of our offices for additional information and to schedule an appointment.
1.2 cm invasive ductal cancer seen only on screening breast ultrasound. Cancer was not seen on the mammogram due to masking by overlying dense breast tissue.
