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.

Impact of the COVID-19 pandemic on breast cancer mortality in the US: estimates from collaborative simulation modeling.
This study’s objective was to project the impact of COVID-19 on future breast cancer mortality between 2020 and 2030. Three established Cancer Intervention and Surveillance Modeling Network breast cancer models were used to model reductions in mammography screening use, delays in symptomatic cancer diagnosis, and reduced use of chemotherapy for women with early-stage disease for the first 6 months of the pandemic with return to prepandemic patterns after that time. The models project by 2030 950 cumulative excess breast cancers deaths related to reduced screening, 1314 deaths associated with delayed diagnosis of symptomatic cases, and 151 deaths associated with reduced chemotherapy use in women with hormone positive, early-stage cancer.

Assessment of a risk-based approach for triaging mammography examinations during periods of reduced capacity.
Breast cancer screening, surveillance, and diagnostic imaging services were profoundly limited during the initial phase of the coronavirus disease 2019 (COVID-19) pandemic. The objective of this population-based cohort study was to develop a risk-based strategy for triaging mammograms during periods of decreased capacity. The investigators found that clinical indication and individual risk factors were associated with cancer detection and suggest these may be useful for prioritizing mammography in times and settings of decreased capacity.

Disruptions in preventive care: mammograms during the COVID-19 pandemic.
The objective of this study was to measure the extent to which the provision of mammograms was impacted by the COVID-19 pandemic and surrounding guidelines. The data source for the study were de-identified summary data derived from medical claims and eligibility files were provided by Independence Blue Cross for women receiving mammograms. The investigators concluded that the provision of mammograms has been significantly disrupted due to the COVID-19 pandemic.
