The COVID-19 pandemic abruptly changed healthcare services, including breast cancer screening, in the United States. Using real-world electronic health records from over 1.8 million women since 2017, we observed a temporary decrease in screening utilization, followed by a rebound within 6 months of the pandemic. However, the rate of follow-up screening within 24 months of a previous screenings decreased from 77.88% in pre-COVID to 77.41% during COVID-period, with variations across demographic subpopulations. A logistic regression also showed an 6.15% decrease in probability that a woman receives a follow-up screening during COVID-19.
