Covid-19 Pandemic Impact on Breast Cancer Detection-The Major Effects Over an Early Diagnosis

The COVID-19 pandemic has disrupted medical care systems, by decreasing patient addressability to outpatient care. The main objective of this study was to compare the patient’s addressability to breast imaging techniques for diagnosis, and follow-up in the Clinical Emergency County Hospital of Craiova, Romania. We selected the mammographies performed over a period of 4 years (2018-2021) in our clinic. We divided the patients into four groups, one for each year (2018, 2019, 2020, 2021). Furtherly, we merged the data into two groups, one group for the pre-pandemic years (2018 and 2019) and one for the pandemic years (2020 and 2021). In our clinic, the number of mammographies plummeted to 0 during the month of April 2020 due to the lockdown and closure of non-urgent outpatient services in hospitals treating COVID-19 patients, and slowly creeped to 11 in the month of May and peaked to 160 in July (for the rest of the year). There was a huge difference regarding the patient’s addressability to mammography immediately after the lockdown, with a 95.2% less addressability compared to the pre-pandemic period (May 2020 compared to May 2018). As an overall, by comparing both pre-pandemic years included in the study with the pandemic years, we obtained an addressability reduced with 37.3% suggesting the possible future delays in diagnosing breast tumors.
