Background: 
Primary, secondary, and tertiary cancer prevention strategies have substantial potential to reduce cancer morbidity and mortality, yet they remain poorly connected within healthcare systems. This fragmentation limits the effectiveness of prevention efforts across the cancer continuum. Organised cancer screening programmes, as core secondary prevention interventions, offer critical but underused opportunities to integrate primary prevention actions, such as health promotion and risk reduction, as well as to extend prevention efforts to cancer survivors at increased risk of subsequent primary cancers. Strengthening these links requires not only evidence on interventions, but also insights into how programmes are implemented in real-world health systems and translated into policy. 

Objectives: 
This work aims to map existing programmes and pilots that (1) integrate primary cancer prevention into secondary prevention and (2) integrate tertiary prevention into secondary prevention, with a focus on breast, colorectal, and cervical cancers. A further objective is to identify implementation elements relevant for implementation of research into practice and policy, including health system organisation. 

?Methods: 
We conducted a scoping review in accordance with Joanna Briggs Institute guidance and the PRISMA-ScR reporting framework. Peer-reviewed literature published between January 2019 and March 2025 was identified through systematic searches in MEDLINE (via Ovid) and Scopus. This was complemented by purposefully selected practices collected through a survey with EU screening authorities, and public health institutes, as part of the Joint Action EUCanScreen, as well as relevant programme guidelines uploaded to the Guidelines International Network (GIN). Eligible sources included programme descriptions, implementation and observational studies, reviews, and pilot initiatives linking prevention levels within organised screening. Title/abstract and full-text screening were performed independently by two reviewers, with two clinical experts serving as tie-breakers for disagreements. Regular meetings were conducted to foster reliability. Data extraction focused on programme characteristics, prevention linkages, target populations, types of actions, stakeholders, and reported implementation elements. Findings were synthesised descriptively through thematic analysis using implementation research frameworks to guide analysis. 

Results: 
A total of 11,296 records were identified through database searches. Following duplicate removal and screening, 54 articles met the criteria for data extraction. These findings were analysed alongside practices identified through the EUCanScreen survey and GIN guideline contributions. The results presented represent trends, with final analyses currently underway. Preliminary mapping suggests that programmes linking primary to secondary prevention commonly use screening encounters as teachable moments to deliver lifestyle advice, risk communication, or tailored prevention messages. Initiatives linking tertiary to secondary prevention were less present, and focused on facilitating cancer survivors’ participation in screening. Across programmes, commonly reported implementation elements include workforce roles and training, integration within existing screening workflows, and acceptability, while evidence on long-term sustainability and equity impacts remains limited. 

Conclusions and policy implications: 
Findings indicate a growing but fragmented landscape of initiatives seeking to strengthen the cancer prevention continuum through screening programmes. From a policy perspective, embedding primary and tertiary prevention within established screening systems represents a pragmatic opportunity to maximise population health. Final results will inform how integrated and innovative prevention approaches can be operationalised within health systems across Europe.
