Abstract
Global cancer incidence is projected to rise dramatically, with over 35 million new cases anticipated by 2050, disproportionately affecting low- and middle-income countries (LMICs) where up to 70% of cancer deaths are expected to occur. This manuscript provides an in-depth assessment of the structural, economic, and sociocultural barriers that drive cancer care disparities in LMICs, including limited access to prevention, diagnosis, treatment, and palliative care services. Key challenges include shortages in oncology workforce, diagnostic infrastructure, radiotherapy access, and participation in clinical trials. Socioeconomic inequities, stigma, and high out-of-pocket costs further exacerbate delayed care and poor outcomes. Some innovative interventions have improved access and quality of cancer care in resource constrained settings. These include task-shifting models, digital health tools, community-based awareness and screening programs, and South-South collaborations that foster local drug innovation and manufacturing. It also explores emerging strategies in precision medicine, AI-assisted decision making, and tele-oncology tailored to LMICs. The role of public-private partnerships, sustainable financing, and international collaborations in advancing cancer control is critically examined. The future of global oncology hinges on a shift from fragmented, reactive responses to coordinated, data-driven, and sustainable strategies. By strengthening health systems and embracing context-sensitive innovation, the global community can address the widening cancer care gap and improve outcomes for vulnerable populations worldwide.
