PURPOSE: The COVID-19 pandemic significantly impacted breast cancer (BC) surgeries. Most studies showing reduced BC surgical volumes during the pandemic are from single institutions, few have described volume changes in different types of surgical procedures. This study aimed to assess the impact of the pandemic on BC surgery volumes and types at a population level. METHODS: Patients diagnosed with BC between January 1, 2018, and June 25, 2022, in Ontario, Canada, were analysed from population-based datasets. Time periods were defined as pre-pandemic (Jan 2018-Mar 2020), immediate pandemic (Mar-Jun 2020), and peri-pandemic (Jun 2020-Jun 2022). Weekly BC surgery volume and type (lumpectomy, mastectomy, or mastectomy with immediate reconstruction) were evaluated using segmented negative binomial regression models. RESULTS: Among 44 226 patients, 50 440 surgeries were performed. Weekly BC surgeries decreased by 16.9% during the immediate pandemic compared to pre-pandemic levels (180.5 vs. 217.1; p = 0.03). Surgical volumes recovered to pre-pandemic levels by June 2021. Mastectomies represented a higher proportion of BC surgeries during the pandemic (31.1% pre, 36.3% immediate, 32.4% peri-pandemic; p < 0.01). The proportion of mastectomies with immediate reconstruction remained stable during the immediate pandemic but increased in the peri-pandemic (20.1% vs. 17%; p < 0.01). CONCLUSION: There was a significant reduction in all BC surgeries during the pandemic. Mastectomies accounted for a higher proportion of BC surgeries in the pandemic period however access to reconstruction was maintained. Surgical volumes recovered within a year despite ongoing pandemic hospitalizations. Future studies are needed to explore the pandemic's long-term impact on BC care.
