Mammographic breast density can predict risk of lymphedema: JAMA
Images in a 55-year-old woman with a spiculated mass localized in the upper central quadrant (arrow in A, B, D, and E) of right breast detected with digital breast tomosynthesis (DBT) plus synthetic mammography (SM). Breast density was classified as category C with the Breast Imaging Reporting and Data System. Mass was invasive ductal carcinoma, stage I, and was estrogen and progesterone receptor positive and human epidermal growth factor receptor 2 negative. A, Image from SM in craniocaudal view. B, Single-slice DBT image in craniocaudal view. C, Magnification of the lesion depicted in B. D, Image from SM in mediolateral oblique view. E, Single-slice DBT image in mediolateral oblique view. F, Magnification of the lesion depicted in E.

Ontario, Canada: Mammographic breast density can be used to predict lymphedema risk and provide volumetric estimates for lymphedema severity., suggests a recent study in the journal JAMA Network Open. According to the study, patients with low breast density were at higher risk of severe lymphedema.
About 20% of breast cancer patients who undergo axillary lymph node dissection will develop lymphedema. There is a need for robust risk models, to approximately monitor and triage these patients for timely diagnosis and treatment. Considering this, Jennifer Yin Yee Kwan, University of Toronto, Toronto, Ontario, Canada, and colleagues evaluated the prognostic value of mammographic breast density in estimating lymphedema severity.
