The OECI Oncology Days represent an important forum for dialogue, exchange, and cooperation among OECI Members, offering the opportunity to strengthen networks and deepen knowledge of the OECI mission, strategy, and programme of activities. The 2026 Edition will be held in Warsaw from 17 to 19 June, in collaboration with the Maria Skłodowska-Curie National Research Institute of Oncology.

The event is expected to attract more than 400 participants, who will engage in discussions on the OECI Accreditation and Designation Programme, the activities of the OECI Working Groups, and other initiatives carried out by OECI in the framework of the EU Cancer Mission and Europe’s Beating Cancer Plan. For the first time, the 2026 Edition will also host a dedicated session of the OECI Young Assembly and Board.

The scientific conference will address two main themes:

• New technologies in Primary and Secondary Prevention
• National Cancer Networks
