214. Deputy Róisín Shortall asked the Minister for Health the number and proportion of people who were diagnosed with breast cancer at each stage, that is, stage 1, 2, 3, 4 and unknown, in each quarter in each of the years 2012 to 2023, in tabular form. [30069/23]

Amharc ar fhreagraI propose to take Questions Nos. 214 to 216, inclusive, together.
The National Cancer Registry Ireland (NCRI) has a statutory obligation to collate information in relation to cancer incidence, prevalence, stage at diagnosis, treatment, survival, and mortality. This type of information will normally only be finalised and made available 2 to 3 years after the year of incidence, in keeping with international standards. Officials in my Department contacted the NCRI for the most up to date information and have collated the below information based on what they received.
Stage breakdown of cancers diagnosed 2012-2020, by selected cancer site
Data for years 2021 onwards are substantially less complete and are not included here, pending further compilation and validation by NCRI, in keeping with international standards.
Figures are based on the major histological cancer subtype(s) at the sites listed and use the TNM 5th edition classification of stage for cases diagnosed 2012-2013 and the TNM 7th edition classification for cases diagnosed 2014-2020. Staging criteria are not directly comparable between the earlier (2012-2013) and later (2014-2020) diagnosis years. Non-stageable histological subtypes are excluded, and carcinoids and gastrointestinal stromal tumours are also excluded for colorectal cancer (to improve continuity with pre-2014 data). For all three cancers listed, data are provisional for 2018 and to a lesser extent 2017, and subject to further updating by NCRI. For lung cancer, data are also provisional for 2019 and 2020. In these years, there is a higher proportion of cases of unknown stage, and the numbers and relative proportions of Stage IV cases, in particular, may be underestimated in these years, as information to confirm Stage IV status typically takes longer to compile.
The data are set out in the table at the following link:
