To assess whether the COVID-19 pandemic delayed breast cancer diagnosis in Taiwan, an Asian country with a low COVID-19 incidence.
The institutional review board approved this retrospective study at a public academic medical center. The monthly volume of breast biopsies and breast cancers during the COVID-19 pandemic (between January 1 and July 31, 2020) was compared to the same period a year earlier (pre-COVID-19).

| 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. | ||

The test period of the COVID-19 pandemic was between January 1 and July 31, 2020. 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.
