Cancer care is one of the most complex areas of medicine. A single patient may see surgeons, medical oncologists, radiation oncologists, radiologists, pathologists and nurses over months or years of treatment. Each step generates data, from imaging and lab results to chemotherapy plans and radiation doses. Managing this information safely and efficiently is essential to delivering high-quality care, and that is the role of oncology information systems.

Market Size and Forecast

According to Polaris Market Research, the global oncology information systems market was valued at USD 3.13 billion in 2025. The market is expected to reach USD 3.38 billion in 2026 and USD 6.27 billion by 2034, growing at a CAGR of 8.03% from 2026 to 2034. Rising cancer incidence and growing investment in healthcare IT are fueling this growth.

What Are Oncology Information Systems?

Oncology information systems are specialized software platforms designed to manage the clinical, administrative and treatment data involved in cancer care. They include oncology-specific electronic medical records, treatment planning systems, chemotherapy order management, radiation oncology management and patient scheduling tools. An oncology EMR or oncology EHR differs from a general hospital record system because it is built around cancer-specific workflows, such as treatment protocols, staging, dose tracking and multidisciplinary tumor boards. These systems help care teams coordinate treatment, reduce errors and track outcomes.

Key Market Drivers

Rising Global Cancer Incidence

The number of new cancer cases continues to rise worldwide, driven by aging populations, lifestyle factors and improved detection. Cancer centers and hospitals need robust systems to manage growing patient volumes, coordinate complex treatments and maintain detailed records over long periods.

Government Initiatives and EHR Adoption

Government programs promoting electronic health records, interoperability and healthcare IT investment are encouraging hospitals and cancer centers to upgrade their systems. Quality reporting requirements and value-based care programs also increase the need for accurate data capture and outcome tracking.

Segment Insights

Polaris Market Research segments the oncology information systems market by product and services and by application. By product and services, software led the market with a 53.0% share in 2025. Software includes patient information systems, treatment planning systems and oncology analytics tools that support daily clinical operations. Professional services, such as implementation, integration, training and support, are the fastest-growing segment, with a projected CAGR of 11.9%, as healthcare organizations need expert help to deploy and optimize complex systems.

By application, medical oncology held a 36.0% share in 2025. Medical oncology involves managing chemotherapy, targeted therapy and immunotherapy regimens, which require precise ordering, dosing and monitoring. Radiation oncology relies heavily on treatment planning and delivery management systems, while surgical oncology is expected to grow at 7.5% as surgical teams integrate imaging and pathology data into planning and follow-up.

Regional Analysis

North America led the global oncology information systems market with a 44.1% share in 2025. High cancer care spending, widespread EHR adoption, advanced radiation therapy infrastructure and the presence of leading health IT vendors support the region's leadership. Europe is investing in digital health and cancer care programs, while Asia Pacific is expected to grow as countries expand cancer treatment capacity and modernize hospital IT systems.

Benefits for Care Teams and Patients

Oncology information systems help reduce medication errors, standardize treatment protocols, improve communication among care teams and give patients better access to their information. They also support research by making it easier to collect and analyze real-world data on treatment outcomes. Integration with patient portals and telehealth tools helps keep patients engaged throughout their care journey.

Challenges

High implementation costs, complex integration with existing hospital systems and the need for staff training can slow adoption, particularly for smaller cancer centers. Data security and interoperability between different vendors' systems are also ongoing concerns.

Competitive Landscape

Key players covered in the Polaris Market Research report include Elekta AB, Flatiron Health (F. Hoffmann-La Roche Ltd), RaySearch Laboratories AB, Epic Systems Corporation, Varian Medical Systems (Siemens Healthineers) and Bogardus Medical Systems. These companies offer oncology software, treatment planning tools and data platforms, and many are investing in cloud solutions, AI and real-world data analytics.

Future Outlook

Oncology information systems are becoming the digital backbone of cancer care. As treatments become more personalized and data-intensive, the need for specialized, integrated software will continue to grow. With the market expected to reach USD 6.27 billion by 2034, vendors that deliver interoperable, user-friendly and data-rich platforms will be best positioned to support cancer centers and improve patient outcomes.
