Proposals must focus on implementation research for the primary and/or secondary prevention of cancer in LMICs and/or in populations facing conditions of vulnerability in HICs. Proposals must build on evidence-based interventions (including cost-effectiveness) for the respective population groups under defined contextual circumstances. For promising interventions, a limited validation period can be envisaged. However, the core of the research activities should focus on their implementation in real-life settings. The proposed interventions should be gender responsive. Deadline date: Please refer to funding partners’ timelines.
