This study explores the impact of the COVID-19 pandemic on the diagnosis of basal cell carcinoma (BCC) in Lower Silesia, Poland, comparing pre-pandemic, pandemic, and post-pandemic periods. It investigates how different medical facilities adapted to the pandemic's challenges and the subsequent implications for cancer diagnosis. Data from histopathology and cytology laboratories were analyzed, focusing on BCC diagnoses from 2018 to 2022. This study included various medical centers categorized by size and source of implementation. Statistical analyses were conducted to compare diagnoses before, during, and after the pandemic. During the initial wave of the pandemic, there was a significant reduction in newly diagnosed BCC cases, followed by a surge post-pandemic. Larger medical centers adapted more effectively, while district hospitals faced challenges. Private practices maintained stable diagnosis rates. The increase in diagnoses post-pandemic suggests a backlog of undiagnosed cases during the pandemic. Challenges in accessing healthcare during the pandemic led to delayed cancer diagnoses. Larger medical centers were better equipped to handle the crisis, while district hospitals struggled. Private practices maintained stability, possibly due to pre-scheduled appointments. Recommendations include public education on symptom recognition and standardizing histopathological evaluation protocols. Despite data limitations, this study provides valuable insights into the pandemic's impact on cancer diagnosis, highlighting the need for proactive measures in future health crises to ensure timely detection and treatment of cancer cases.
