Digital health tools reshape cancer prevention alongside traditional in-person care

Digital health technologies are no longer simply an add-on to traditional cancer prevention programs. According to a new commentary published in Cancer Causes & Control, the rapid expansion of virtual platforms for cancer-related psychosocial and behavioral interventions may be fundamentally redefining how prevention reaches populations, rather than merely offering a supplementary digital channel alongside established in-person services. The paper, authored by Chinenye Lynette Ejezie of Towson University, proposes a framework for thinking about cancer prevention delivery across in-person, digital, and hybrid modalities, and argues that the time has come to rethink which interventions belong where.

At the heart of the commentary is a redistribution argument. Not all cancer prevention activities are equally suited to every delivery mode. Interventions that require physical presence, clinical infrastructure, and direct human contact—such as human papillomavirus (HPV) vaccination and hepatitis B vaccination, both of which prevent virus-driven malignancies—are likely to remain anchored in in-person services, including school-based and clinic-based programs. By contrast, cancer prevention-related education and psychosocial interventions can increasingly be delivered through digital platforms, potentially improving access and continuity of care for populations that have historically faced barriers to attending physical health facilities. The commentary suggests that recognizing this division of labor, rather than treating digital and in-person approaches as competitors, could lead to more efficient and equitable prevention systems.

The evidence base for digital delivery has grown substantially over the past decade. A scoping review of reviews published in The Lancet Digital Health in 2023 documented the breadth of digital health and telehealth applications across the cancer care continuum, from prevention and screening through survivorship. The COVID-19 pandemic acted as a powerful accelerant: a cross-sectional analysis published in the Journal of Medical Internet Research in 2020 showed how quickly a comprehensive cancer center could pivot to telehealth in response to lockdowns, while subsequent research documented both the reach and the unevenness of that transition. Studies of colorectal cancer patients in the United States during the pandemic revealed that access to telehealth services varied considerably, foreshadowing concerns about equity that persist today.

Ejezie’s commentary draws particular attention to the question of whether digital interventions can match the effectiveness of their face-to-face counterparts. The evidence here is nuanced. A 2025 longitudinal study published in Frontiers in Psychology compared effectiveness and therapeutic alliance between face-to-face and online psychological interventions and found that online delivery can sustain meaningful therapeutic relationships. On the behavioral side, a systematic review and meta-analysis in Disability and Rehabilitation examined face-to-face behavior change counseling interventions on physical activity in cancer survivors, providing a benchmark against which digital and hybrid approaches can be measured. Hybrid models are also generating real-world evidence: the STOP program, a smoking prevention and cessation training initiative for cancer care providers in Colombia and Peru described in the Journal of Cancer Education, demonstrated how blended delivery can extend prevention training across international settings where purely in-person approaches would be logistically and financially prohibitive.

Yet the commentary is careful not to overstate the promise of digital tools. It highlights three interlocking concerns: fragmentation, equity, and implementation. Fragmentation arises when digital services are bolted onto health systems without integration into existing care pathways, leaving patients to navigate disconnected silos of in-person and virtual care. Equity concerns stem from well-documented disparities in digital access. A scoping review published in the Journal of Racial and Ethnic Health Disparities in 2025, led by the same author, examined digital health interventions for cancer prevention among racial and ethnic minority groups in the United States and underscored how benefits depend heavily on connectivity, device ownership, digital literacy, and culturally tailored design. A narrative review in the Journal of Medical Internet Research on telehealth across rural American communities reached similar conclusions, noting that rural populations stand to gain enormously from remote services but are often precisely the groups least equipped to use them.

Implementation barriers form the third pillar of concern. A qualitative study of health care professionals’ experiences with a digitally enabled care pathway, published in the Journal of Medical Internet Research in 2019, illustrated how clinician workflows, training needs, and organizational culture shape whether digital tools succeed or stall. More recently, a 2025 scoping review in JAMIA Open catalogued the persistent barriers to telehealth uptake and use, spanning technical, financial, regulatory, and interpersonal dimensions. Research on medical oncology professionals’ perceptions of telehealth video visits, published in JAMA Network Open in 2021, found that while many clinicians valued the convenience and reach of virtual care, they also worried about limitations in physical examination, communication quality, and the erosion of relational aspects of care. Patient preferences add another layer of complexity: a study of a large multispecialty practice published in the Journal of Telemedicine and Telecare showed that patients differ widely in how much virtual care they want, with many preferring a blend of remote and in-person encounters depending on the purpose of the visit.

Against this backdrop, the commentary’s proposed framework organizes prevention delivery by modality fit. Vaccination programs illustrate the case for physical delivery. A systematic review in BMC Public Health on school-based vaccination programs in high-income countries emphasized the importance of organizational and delivery structures—consent processes, scheduling, and school infrastructure—that simply cannot be replicated virtually. Workplace health promotion research, also published in BMC Public Health, has documented attendance barriers even for motivated participants, suggesting that shifting educational and counseling components of such programs to digital channels could relieve some of the logistical burden while preserving in-person contacts for procedures that require them. In this vision, HPV and hepatitis B vaccination campaigns remain firmly physical events, while the surrounding ecosystem of education, reminder systems, counseling, and follow-up migrates increasingly to screens.

The commentary also situates these proposals within emerging regulatory and standards architectures. The World Health Organization’s 2019 guideline on digital interventions for health system strengthening provided an early roadmap for governments, and the National Institute for Health and Care Excellence in the United Kingdom has developed an evidence standards framework for digital health and care technologies that is increasingly influential globally. Recent work in JMIR mHealth and uHealth has examined how evolving digital health technologies can align with and enhance that framework. In oncology specifically, the American Society of Clinical Oncology has issued telehealth standards and practice recommendations, published in JCO Oncology Practice, that offer professional guidance on appropriate use. The commentary argues that cancer prevention programs should engage with these standards from the outset, embedding evaluation and evidence generation into digital and hybrid program design rather than retrofitting rigor after deployment.

Methodologically, the commentary points to hybrid experimental designs as a promising route for building the next generation of prevention interventions. Work published in Advances in Methods and Practices in Psychological Science in 2022 has articulated what, why, and how of hybrid designs for intervention development—approaches that combine the iterative, optimization-oriented logic of engineering with the inferential rigor of clinical trials. Applied to cancer prevention, such designs could help researchers determine which components of a multicomponent prevention program are best delivered digitally, which require in-person contact, and how the two can be sequenced for maximum effect. This is a departure from the traditional paradigm in which a program was designed for one modality and evaluated accordingly.

The stakes of getting this right are considerable. Cancer remains a leading cause of death worldwide, and a large fraction of cancers are potentially preventable through vaccination, tobacco control, healthy behavior promotion, and early detection of precancerous lesions. Traditional in-person programs have achieved real successes but face chronic constraints: staffing shortages, geographic barriers, no-show rates, and the difficulty of sustaining contact with participants over the long periods required for behavior change to take hold. Digital platforms offer potential solutions to several of these constraints—continuous availability, scalability, automated reminders, and the ability to reach people in their homes—but only if the underlying issues of access, design quality, and system integration are addressed. Qualitative systematic review evidence published in the Journal of Medical Internet Research in 2023 on culturally and linguistically diverse populations highlighted barriers ranging from language and health literacy to trust and privacy concerns, all of which must be engineered into digital prevention tools rather than treated as afterthoughts.

Ejezie’s commentary does not call for the replacement of in-person programs but for their strategic repositioning. In the framework proposed, traditional programs remain indispensable for vaccination, physical examinations, specimen collection, and the relational dimensions of care that many patients and providers prize, while digital platforms take on an expanding share of education, psychosocial support, behavioral counseling, and longitudinal engagement. Hybrid models, exemplified by programs like STOP in Latin America, offer a template for combining the strengths of both. The author emphasizes, however, that the benefits of this redistribution are conditional—they depend on digital access, program design, and implementation context. Where those conditions are not met, digital expansion risks widening rather than narrowing disparities.

For policymakers and program leaders, the message is that the future of cancer prevention is neither fully virtual nor stubbornly analog, but deliberately mixed. Decisions about which services to move online, which to keep in person, and how to knit the two together should be driven by evidence on modality fit, equity impact, and implementation feasibility. As digital health continues its rapid evolution, the commentary suggests that the programs that thrive will be those that treat modality choice as a design variable to be optimized—measured, evaluated, and refined—rather than as a default inherited from history or a fad adopted under pressure.
