The findings in this report are based on registered and projected cancer cases in 2021, using data available in March 2023. 

NCRI expects to publish a more definitive update on 2021 case numbers later this year.

Key findings:

• Preliminary data on the impact of the COVID-19 pandemic indicates that the number of cancer cases diagnosed in 2021 was down 1,665 cases or 6% lower than projected.
• This is a smaller shortfall in diagnosis than the 10% observed in 2020.
• Colorectal, female breast, and cervical cancer case numbers, which were notably impacted by the COVID-19 pandemic in 2020, returned to expected case numbers in 2021.
• Liver, pancreatic and kidney cancers appear to have been most significantly impacted by the disruptions that occurred due to COVID-19.
• The combined number of diagnosed cancers during 2020 and 2021 was down 4,320 cases or 8% lower than projected.

Further collaborative work is ongoing to assess the impacts of COVID-19 related disruption on cancer services and outcomes in Ireland.
