The number of obstructive colorectal cancers in Japan has increased during the COVID-19 pandemic: A retrospective single-center cohort study

Abstract

Our findings indicate the possibility that the discovery of CRCs in patients could be delayed due to the halt in screenings caused by the COVID-19 pandemic, resulting in the increase of obstructive CRCs. These results highlight the importance of cancer screening and suggest that the screening system for cancers should be reorganized before future pandemics.
