GRELL & ENCR

Ascension Meeting 2025

The 49th GRELL Annual Meeting will take place in Porto, Portugal, from 27th to 30th May 2025.

The GRELL 2025 meeting will be particularly special, as it will also host the ENCR (European Network of Cancer Registries) meeting. In this context, workshops will be organized on Tuesday, followed by a 3-day GRELL-ENCR conference.

Stay tuned! Further information will follow soon.

The GRELL network is one of the oldest cancer research associations worldwide, with highest expertise in cancer epidemiology and cancer data collection. It aims to promote cancer research and cancer epidemiology to develop multicentre epidemiological studies, to advocate cancer cases registration and contribute to training of professionals and researchers in cancer epidemiology. The GRELL network plays an important role for the current strong position of cancer epidemiology worldwide.
The European Network of Cancer Registries (ENCR) promotes collaboration between cancer registries, defines data collection standards, provides training for cancer registry personnel and regularly disseminates information on cancer incidence and mortality in Europe.
The ENCR is in operation since 1990 and was established within the framework of the Europe Against Cancer programme of the European Commission on the initiative of the International Agency for Research of Cancer (IARC), Association of Nordic Cancer Registries (ANCR), International Association of Cancer Registries (IACR) and Latin Language Registry Group (GRELL).
