Radiation Oncology Market Size and Share Analysis: Opportunities for Cancer Care Equipment Manufacturers

The global radiation oncology market size was valued at USD 11.42 billion in 2025 and is projected to grow from USD 12.78 billion in 2026 to USD 31.41 billion by 2034, registering a CAGR of 11.9% during the forecast period from 2026 to 2034. North America dominated the radiation oncology market with a market share of 39.2% in 2025.

Radiation oncology is a medical specialty that uses radiation to treat cancer. It is an important part of cancer care and is often used alongside surgery, chemotherapy, and other treatments. Radiation therapy uses high-energy radiation to damage cancer cells and control their growth. In external beam radiation therapy, a machine directs radiation toward the targeted area of the body. Internal radiation therapy, including brachytherapy, places a radioactive source inside or near the tumor.

The radiation oncology market includes treatment machines, radiation delivery systems, treatment-planning technologies, and related equipment used by hospitals and specialized cancer centers. Advances in imaging, computer-based planning, and radiation delivery are helping healthcare professionals target tumors more accurately while limiting exposure to surrounding healthy tissues. As healthcare providers seek effective cancer treatment options, demand for modern radiation oncology technologies is expected to increase.

Market Drivers

Rising Adoption of Radiotherapy

The growing use of radiation therapy for different types of cancer is a major factor supporting market growth. Radiotherapy can be used as a primary treatment or combined with surgery and chemotherapy, depending on the cancer type, stage, and individual treatment plan. Improvements in radiation delivery also allow clinicians to direct radiation more precisely toward tumors.

Demand for radiotherapy equipment is particularly important in countries where cancer treatment infrastructure is expanding. Developing healthcare systems need additional treatment machines and facilities to improve access to cancer care. The Straits Research report highlights the need for additional radiotherapy machines in low- and middle-income countries, including China, India, and Brazil. These needs create opportunities for equipment manufacturers and technology providers.

Increasing Healthcare Expenditure

Higher healthcare spending can support investment in advanced cancer diagnosis and treatment. Hospitals and cancer centers may use additional funding to purchase modern radiation therapy systems, upgrade existing equipment, and improve treatment planning services. Public investment, private healthcare expansion, and cancer-care programs can also help increase access to radiotherapy.

As healthcare providers focus on treatment quality and clinical efficiency, demand may grow for systems that offer improved precision, better imaging guidance, and more efficient treatment workflows. However, the effect of increased spending depends on how funding is distributed and whether patients and healthcare facilities can afford the cost of treatment.

Market Restraints

Shortage of Skilled Radiotherapy Professionals

A shortage of trained professionals can limit the adoption of advanced radiation oncology systems. Radiotherapy requires coordinated work by radiation oncologists, medical physicists, radiographers, dosimetrists, nurses, and other healthcare specialists. These professionals help assess patients, plan radiation doses, operate equipment, and manage treatment-related side effects.

Advanced treatment systems require specialized training and technical knowledge. When facilities lack enough qualified staff, they may struggle to use their equipment efficiently, provide timely treatment, or expand services. Workload pressures and the retirement of experienced professionals can further increase staffing challenges. Investment in education, training, and workforce development is therefore important for supporting market growth.

Market Opportunities

Technological Advancements in Radiotherapy

Technological innovation is creating opportunities across the radiation oncology market. Image-Guided Radiation Therapy (IGRT), Intensity-Modulated Radiation Therapy (IMRT), Volumetric-Modulated Arc Therapy (VMAT), stereotactic radiotherapy, and proton therapy are among the advanced approaches discussed in the market report.

These technologies can help clinicians plan and deliver radiation more accurately. Imaging guidance supports the localization of tumors, while advanced planning systems help determine how radiation should be distributed. Some techniques can deliver concentrated doses to specific targets while reducing unnecessary exposure to nearby tissues. Continued development of treatment-planning software, imaging systems, and adaptive treatment methods may improve clinical workflows and support demand for next-generation equipment.

Opportunities may also arise as healthcare systems develop new cancer centers and upgrade existing facilities. Manufacturers that provide reliable equipment, technical support, training, and workflow solutions may be better positioned to serve these expanding needs.

Radiation Oncology Market Segmentation

The market is segmented by therapy type, technology, application, end user, and region.

By Therapy Type

The market is divided into external beam radiation therapy and internal beam radiation therapy. External beam radiation therapy (EBRT) uses a machine outside the body to direct radiation toward a tumor. It includes linear accelerators and advanced systems such as stereotactic and proton-based technologies. The report identifies external beam radiation therapy as the dominant therapy-type segment.

Internal beam radiation therapy includes brachytherapy, in which a radioactive source is placed inside or near the treatment area. Brachytherapy is used for selected cancers and can offer targeted radiation delivery. The choice between external and internal radiation therapy depends on the cancer type, tumor location, and clinical requirements.
