Breast biopsy recommendations and breast cancers diagnosed during the COVID-19 pandemic.
The authors sought to examine breast biopsy recommendations and breast cancers diagnosed before and during the COVID-19 pandemic by mode of detection and women's characteristics. Using data from the Breast Cancer Surveillance Consortium, they found that there were substantially fewer breast biopsies with cancer diagnoses during the COVID-19 pandemic from March to September 2020 compared to the same period in 2019, with Asian and Hispanic women experiencing the largest declines followed by Black women.

Comparing mammographic density assessed by digital breast tomosynthesis or digital mammography: the Breast Cancer Surveillance Consortium.
This study’s purpose was to assess the consistency of Breast Imaging Reporting and Data System (BI-RADS) breast density reporting comparing digital breast tomosynthesis (DBT) with digital mammography (DM) and to evaluate density as a breast cancer risk factor when assessed using DM versus DBT. A secondary analysis of data from the Breast Cancer Surveillance Consortium was used from 342,149 women aged 40-79 years who underwent at least two screening mammography examinations less than 36 months apart. There were no significant differences in breast density assessment in pairs consisting of one DM and one DBT examination (57,516 of 74,729 [77%]), two DM examinations (238,678 of 301,743 [79%]), and two DBT examinations (20,763 of 26,854). Results were similar when pair analysis was restricted to readings by the same radiologist. The breast cancer hazard ratios (HRs) for breast density were similar for DM and DBT. The HRs for density acquired using DM and DBT, respectively, were 0.55 and 0.37 for almost entirely fat, 1.47 and 1.36 for heterogeneously dense, and 1.72 and 2.05 for extremely dense breasts.
