New York, NY — Dec. 16, 2025 — The global Oncology Information Systems (OIS) market is projected to grow from US$2.9 billion in 2024 to about US$4.0 billion by 2034, at a compound annual growth rate of 3.2% from 2025 to 2034. North America led the market in 2024 with a 39.9% share, generating roughly US$1.2 billion in revenue.
Oncology Information Systems integrate clinical, administrative and operational data to support cancer care workflows, including patient scheduling, treatment planning, chemotherapy management, radiation therapy coordination and electronic medical record integration. By centralizing patient information, OIS platforms enable real-time access for multidisciplinary teams, improving clinical decision-making, continuity of care and operational efficiency.
Market segmentation in 2024 showed the solutions segment accounting for 67.4% of revenue, medical oncology as the largest application with a 42.1% share, and hospitals and diagnostic imaging centers representing 52.3% of end-user revenue.
Regional dynamics are driven by rising cancer incidence and digital health adoption. North America’s leadership reflects high EHR adoption and integrated data management needs; the U.S. cancer incidence rate was 445.8 per 100,000 population for 2018–2022, and 78.6% of U.S. hospitals had EHR and telemedicine systems as of February 2024. Key vendors also reported growth in 2024, with Siemens Healthineers posting 4.7% comparable revenue growth and Varian reporting a 10.5% increase in Q4 FY2024. Asia Pacific is expected to register the fastest CAGR due to increasing cancer caseloads, expanding healthcare infrastructure and government support for digital health initiatives.
Emerging trends shaping the market include the integration of artificial intelligence and machine learning for treatment planning and outcome prediction; cloud-based platforms that improve accessibility and scalability; incorporation of genomic data to support precision medicine; expanded tele-oncology capabilities for remote consultations; real-time data sharing among care teams; patient engagement tools such as portals and mobile apps; and advanced analytics to support research and performance evaluation.
Common use cases for OIS include coordinating multidisciplinary treatment plans, tracking patient progress and outcomes, reducing duplicate tests by consolidating records, enabling remote cancer care through telehealth integration, supporting clinical trial recruitment and monitoring, and automating billing and compliance processes to reduce administrative burden.
Oncology Information Systems are increasingly central to modern cancer care, addressing the complexity of oncology workflows by enhancing care coordination, clinical accuracy and patient safety. Continued investment in analytics, cloud deployment, AI and genomic integration is expected to reinforce OIS value as health systems pursue data-driven, quality-focused oncology services worldwide.
