The purpose of the National Cancer Registry is;

- to identify, collect, classify, record, store and analyse information relating to the incidence and prevalence of cancer and related tumours in Ireland;
- to collect, classify, record and store information in relation to each newly diagnosed individual cancer patient and in relation to each tumour which occurs;
- to promote and facilitate the use of the data thus collected in approved research projects and in the planning and management of services;
- to publish an annual report based on the activities of the Registry;
