Abstract Issue Strategic documents addressing major public health concerns should extend beyond health sector. Cancer control is commonly perceived only as a health issue, thus involving diverse stakeholders is challenging. Description of the problem The inclusion of stakeholders within and beyond the health sector is crucial in the preparation, and through implementation of National Cancer Control Programmes (NCCP). Lessons learned on how to involve and maintain fruitful collaboration with diverse stakeholders in Slovenian NCCP are presented. Results Over the past 14 years Slovenia’s NCCP has built a reliable and reputable partnership with diverse stakeholders, a collaboration that continues to evolve. Efforts extend across multiple sectors, encompassing health, education, employment, research, environment, technology, and non-governmental organizations. NCCP has set up multistakeholder governance structures: an advisory board, board of experts, specialised expert groups, and a group of representatives of cancer hospitals. These groups engage a diverse range of experts and institutions nationwide. Whenever feasible, representatives of patient organizations are included. All these structures hold regular meetings, complemented by an annual event that convenes all stakeholders and also provides an invaluable platform for informal networking. To ensure seamless coordination of all activities, a dedicated team is essential. Our approach has evolved to embrace a dual leadership, comprising both a public health specialist and a clinical expert. Additionally, we benefit from the expertise of communication experts, who offer valuable insights into effectively reaching diverse audiences. Lessons Governing Slovenia’s NCCP by involving diverse stakeholders in planning and implementation activities has demonstrated its effectiveness. Furthermore, we are witnessing an increasing number of new stakeholders actively seeking out to participate in the NCCP. Key messages • Slovenia’s NCCP is recognized for its credibility and strategic approach. • Involving diverse stakeholders in cancer control endeavours has proven effective, fostering trust and partnerships.
