Routine screening mammography has been demonstrated to reduce breast cancer mortality rates. However, mammography is not a perfect screening tool, and this benefit comes at the cost of false-positive recalls, benign biopsies, radiation exposure, and overdiagnosis. The weight that is placed on each of these respective risks relative to mortality reduction will impact the choice of preferred screening strategy. Advances in technology offer the opportunity to increase the benefit-to-risk ratio of breast cancer screening by improving the sensitivity and specificity of mammography, and by providing additional non-invasive diagnostic tools to distinguish between benign and malignant lesions, thus reducing the number of patients required to undergo biopsy.

This session will review recent innovations in breast imaging, including digital breast tomosynthesis (DBT), synthetic mammography, contrast enhanced digital mammography, and tomosynthesis-guided biopsies. The physical principles of these technologies will be reviewed, and the role of each modality with respect to breast cancer screening and diagnosis will be discussed.

The first presentation will focus on the benefits and risks of breast cancer screening, with an emphasis on technological evolution. The second presentation will discuss the adoption of these technologies into clinical practice from the perspective of a breast radiologist. The session will conclude with a physicist sharing her personal experience with breast imaging as a breast cancer patient.

Learning objectives:
1. To discuss the benefits and risks of breast cancer screening , and to understand how this discussion drives and is impacted by technological developments
2. To review the current use of digital breast tomosynthesis (DBT), synthetic mammography, contrast enhanced digital mammography, stereotactic biopsies, and tomosynthesis-guided biopsies in clinical practice
3. To hear one patient’s experience with breast cancer from detection to treatment
4. To reflect on the role of the medical physicist in breast imaging
