COVID-19 2019
Patients receiving biopsies with a BI-RADS assessment of 4 or 5 from mammographic or ultrasonographic exams or combinations of tests were analyzed \[4\]. We further categorized the biopsy data as ultrasound-guided or mammograph-guided biopsy based on procedure coding. Ultrasound-guided core needle biopsy (CNB) was performed for breast lesions visible on ultrasound.

Moreover, the control period of the pre-COVID-19 pandemic was between January 1 and July 31, 2019, before there was any report about the virus. Only patients with complete medical records were eligible for enrollment in this study. Confirmed COVID-19 case numbers in Taiwan were acquired from Taiwan's National Health Command Center \[7\]. Anonymized records of breast biopsies and cancer registration in a single institution in southern Taiwan in the pre-COVID-19 and COVID-19 periods were reviewed.
