The Nordic Cancer Union (NCU) provides funding to support and stimulate collaborative cancer research within the Nordic countries. The research project must be a collaborative effort between researchers from research institutions in three Nordic countries or more. However, if the project’s Nordic dimension is exceptionally strong, two different Nordic participating countries can be considered sufficient. The principal investigator of a research project must be employed in a Nordic research institution. The research project must be cancer relevant, and the effect of collaboration should be synergistic. Funding is restricted to research that is in line with the NCU research strategy: https://ncu.nu/research-strategy/. The revised research strategy was adopted by the Nordic Cancer Union Board in November 2022. NCU research grants are provided for 1-3 years. However, funding for the 2nd and 3rd year is conditional and subjective to approval of a progress report.
