Radiation Therapy in the Oncology Market Size & Outlook, 2025-2033

Radiation Therapy in the Oncology Market Size

The global radiation therapy in the oncology market size was valued at USD 8979.2 Million in 2024 and is anticipated to grow from USD 10944.75 Million in 2025 to reach USD 53327.39 Million by 2033, exhibiting a CAGR of 21.89% during the forecast period (2025–2033).

Radiation therapy in oncology is a treatment method to treat any cancer/tumor with the help of radiation. Radiation therapy uses beams of photons, protons, heavy ions, and other particles. These radiation beams of intense energy are used to destroy or shrink cancer/tumor cells. Roentgen discovered the X-ray in 1895, and since then, ionizing radiation has been applied for cancer treatment. The controlled ionizing radiation dose damages the DNA of the cancer cell when compared with the effect on normal tissues, thus providing radiation treatment benefits for cancer patients.

The term' radiation therapy' primarily refers to external and internal beam radiation therapy. External beam radiation therapy is done with the help of a machine outside the patient's body that produces a high-energy radiation beam and then aims the beam at a localized, precise point or area of therapy on the patient's body. However, internal beam radiation therapy places radiation (radioactive source) inside the patient's body. The radiation therapy systems (machines) present in the market are linear accelerators (LINAC), cyclotrons, synchrotrons, synchrocyclotrons, and conventional and electronic brachytherapy systems.

Radiation Therapy in the Oncology Market Growth Factors

Rising Incidence and Prevalence of Neoplastic Patients and Elevating Geriatric Population

Neoplasm is an abnormal tissue mass formed due to the cell growing or dividing unwantedly. The neoplasms are of two types: benign (non-cancerous) and malignant (cancerous). Neoplastic patients are in large numbers, and the number of patients is increasing yearly. Cancer and tumor are often treatable and frequently manageable through early detection and treatment therapy. The neoplasm is also a cause of disability and death on the global level.

Furthermore, cancer and tumor risk increase with age; thus, cancer is known as the disease of old age. In the elderly population, cancer deaths account for about 61% of mortality. According to the National Center for Biotechnology Information (NCBI), about 24% of neoplastic persons are of 65 years of age or older. In order to meet the demand for radiation therapy, cost-effective radiotherapy systems are required to offer high-quality patient treatment for the geriatric population. This factor is expected to act as a driving force for the growth of global market.

Rising Demand for Reduced Radiation Exposure during Radiotherapy

Radiation therapy helps control cancer growth; if the patient has advanced cancer, it helps manage symptoms and relieve pain. These factors increase physicians' and patients' preferences for radiation therapies. Radiation therapy is advantageous as they have fewer side effects than chemotherapy as it targets only the tumor area in the body. Though radiation therapy still has some side effects, the rising preference for radiation therapy is due to the technological advancement in the particle beam. Conventional radiotherapy was done via photon (Cobalt-60), which resulted in unwanted radiation exposure. This photon beam is now changed to a proton or heavy ion beam, which delivers dose to a particular point only, thus resulting in reduced unwanted radiation exposure. Therefore, this is also leading to the growth of modern radiation therapy in the oncology market.

Market Restraining Factors

High Cost of Radiotherapy Systems and Associated Procedures

One of the prime challenges in the radiotherapy market is the high capital cost of the system, its associated equipment, maintenance services, and the cost of the procedure. Currently, modern radiation therapy systems have a very high initial price, requiring an arrangement for considerable capital investment from independent private surgeons and hospitals. A single conventional X-ray radiation therapy system costs around USD 3 million, and a big center or hospital will have more than one system, thus increasing the system's installation cost.

Along with the capital system, a special radiation shield infrastructure is required, and the electricity used also adds to the cost of owning a radiation therapy system. All radiation therapy system manufacturers face several cost-associated related challenges in convincing the end users to own a system. Furthermore, when not covered by health insurance, the radiation treatment cost can range from USD 10,000 to USD 50,000 or more, depending on cancer/tumor type, number of treatment sessions required, type of radiation used, and other medical factors. Such factors restrict market growth.

Market Opportunity

Development of Low-Cost Cancer Treatment Center

Despite the high prices of the systems the manufacturers offer, some end-users are willing to set up a center. The government also supports them in developing the cancer treatment center through funding. A prominent cancer treatment center would require multiple radiation therapy systems. Therefore, the manufacturers provide two options for installation: a modest LINAC or Cyclotron radiation therapy system or a multi-room capable radiation therapy system. Implementing either solution of two means the installation cost is still higher.

Manufacturers are trying to improve the workflow to increase the working efficiency of the system, which will result in profit generation for the end-user. The continuous effort of expanding the workflow, integration of MRI and PET-CT technology, and implementation of real-time guided therapy for radiation therapy will reduce the running cost of the system in a way that the end user will be able to adjust 2-3 patients as compared to one in the older and conventional methods. Therefore, increasing the return on investment in radiation therapy systems creates opportunities for market growth.

Radiation Type Insights

The external beam radiation segment accounts for the largest market share and is anticipated to exhibit a CAGR of 4.6% over the forecast period. External beam radiation is where the radiation beam or beams of x-ray, photon, proton, electron, or heavy ion is generated outside the patient's body by a particle accelerator. These radiation beams are delivered to the patient's cancer/tumor to either shrink or destroy it. In addition, the adoption of modern external beam radiation systems is rapidly increasing due to the significant change in the radiation beam type. This allows clinicians to reduce the radiation exposure to healthy tissues surrounding the target area and automate the radiation therapy to improve the efficacy and precise and accurate radiation dose delivery.

Product Type Insights

The oncology system segment dominates the global market and is expected to grow at a CAGR of 4.4% over the forecast period. Radiation therapy systems in the oncology segment include conventional radiation systems and brachytherapy systems, which are most used in the market. These systems allow clinicians to perform cancer treatments through external or internal beam radiation. The most common radiation beam is a superficial X-ray or photon for teletherapy. The brachytherapy consists of various radioactive sources depending on the type of cancer/tumor and its location.

Therapy Insights

The stereotactic radiosurgery (SRS) segment owns the highest market share and is predicted to exhibit a CAGR of 5.2% over the forecast period. Stereotactic radiosurgery (SRS) is not surgery as it does not include any incision or general anesthesia. SRS was created by neurosurgeons and physicists about five decades ago to deliver radiation to localized targets in the brain. The SRS destroys the DNA of the tumor cells in the same manner as another form of radiation, resulting in the tumor cells dying because of the inability to grow. In addition, the SRS uses 3D computerized imaging and a frame placed on the patient's head to direct the radiation beam to a precise target and deliver a high radiation dose in a single session.

End-User Insights

The hospitals and medical research institutes segment is the most significant contributor to the market and is estimated to exhibit a CAGR of 4.8% over the forecast period. The end-user of the hospitals and medical research institutes segment is the primary buyer of radiation therapy systems, owing to the increasing geriatric population, rising incidence and prevalence of cancer/ tumor, and continuous technological advancements in radiation therapy systems.
