Recurrent breast cancer diagnosis delayed by COVID-19 pandemic.

We describe the case of a 64-year-old female with a no relevant medical history. Screening mammography in March 2020 demonstrated calcifications in the right breast, and a diagnostic mammogram was recommended. In the months that followed, the patient experienced tissue changes in the right breast but avoided returning to the facility as the COVID-19 pandemic worsened. The patient returned for a diagnostic mammogram in September of 2020, which indicated suspicious lymph nodes and an increase in calcifications. Further analysis through ultrasound-guided core biopsy ultimately led to a right mastectomy and lymph node biopsy, which were performed in October 2020. Pathology results confirmed the diagnosis of invasive ductal carcinoma with lobular features.
