SARS-CoV-2 as a new possible long-lasting determining factor impacting cancer death numbers. Based on the example of breast, colorectal and cervical cancer in Poland

Abstract

Introduction. So far, cancer burden has mainly been connected with the age structure of a given population and changes in risk factor exposure combined with lifestyle. Nowadays, available data indicates that the SARS-CoV-2 virus may be a new strong agent impacting the number of cancer deaths in the future. Material and methods. In our study we analyzed changes in cancer screening as well as participation in a fast path of oncological diagnosis and treatment – before and during the SARS-CoV-2 pandemic in Poland – taking into consideration breast, colorectal and cervical cancer. Results. We investigated substantial changes connected with the pandemic. In the case of cancer screening – despite the end of lockdown – population coverage and participation percentages are still lower than before the pandemic. Discussion. Similar results were observed in different studies, e.g. in the United Kingdom similar declines are evident as well as a simultaneous prognosis of an increase in cancer death numbers. Conclusions. Immediate health policy actions are needed in order to reverse unfavorable trends in cancer screening, treatment and ultimately in the number of cancer deaths in Poland.
