Radiation Oncology considers all aspects of research that affect the application of radiation to treat cancer. Radiation oncology (radiotherapy/radiotherapy) is a medical specialty that must be included in a multidisciplinary approach to treating cancer. A linear accelerator normally provides high-energy x-rays (photons). These painless, non-invasive therapeutic X-rays are used to treat many cancers. It uses photons with high energy, often provided by a linear accelerator. Several cancers are treated with these painless, non-invasive therapeutic X-rays.

A multidisciplinary team of radiation oncologists (specialist doctors), nurses, radiation therapists, and medical physicists assess, plan treatment, and assist patients with any side effects they may experience. An extremely cost-effective cancer treatment is radiation therapy. Radiation oncology uses cutting-edge technology and cutting-edge treatment methods. Several cancer patients have profited from recent advancements, which have led to improved cure rates, fewer side effects, quicker recovery times, and fewer treatments overall.

Type Insights

The market is bifurcated into external beam radiation therapy and internal beam radiation therapy. The external beam radiation therapy segment dominates the global market and is estimated to exhibit a CAGR of 7.4% over the forecast period. EBRT includes electron-emitting high-energy Linear Accelerators (LINAC), compact advanced radiotherapy systems, and proton beam therapy systems. EBRT is easy to deliver as radiologists can control the rate of radiation. Numerous applications are available for small, advanced radiotherapy systems like CyberKnife, Gamma Knife, and Tomotherapy. Proton therapy is one of the key types of EBRT and is anticipated to gain substantial market share over the forecast period.

The internal beam radiation therapy segment is further categorized into brachytherapy, systemic beam radiation therapy, and others. The brachytherapy segment dominates the market owing to the development and approval of new brachytherapy devices for treating various cancers.

Technology Insights

The market is divided into external beam radiation therapy and brachytherapy. The external beam radiation therapy (Intensity-Modulated Radiation Therapy (IMRT)) segment is the largest contributor to the radiation oncology market share and is estimated to exhibit a CAGR of 5.2% over the forecast period. External beam radiation therapy (EBRT) has been further categorized into Image-Guided Radiation Therapy (IGRT), Intensity-Modulated Radiation Therapy (IMRT), stereotactic radiotherapy, proton beam radiotherapy, 3D-CRT, and VMAT. These technologies are also non-invasive, which is anticipated to increase patient compliance. IMRT dominates the EBRT segment and is one of the conformal radiation therapy technologies. IMRT allows change in radiation intensity during treatment to specifically target cancer cells and limit the damage to adjoining healthy tissues. In addition, linear accelerators deliver radiation doses to the exact dimensions of tumors. IMRT is beneficial for head and neck cancer treatment as it lowers the risk of damage to salivary glands and the spinal cord.

Brachytherapy has been further categorized into low-dose brachytherapy and high-dose brachytherapy. These therapies do not necessarily involve hospitalization. Moreover, brachytherapy reduces the procedure time. These factors augment the growth of the brachytherapy segment. In Low Dose Rate (LDR), radioactive sources (seeds) are placed inside or adjacent to the tumors for several days of treatment. These sources emit low radiation levels for several weeks, and their strength of emitting radiation steadily reduces to zero. Furthermore, High Dose Rate (HDR) brachytherapy held the largest market share owing to the short procedure time, higher efficacy, and protection from radiation exposure. HDR brachytherapy is an outpatient procedure. However, sometimes, patients are admitted to hospitals for one to two days to undergo HDR treatments using the same applicator.

Application Insights

The market is segmented into external beam radiation therapy and internal beam radiation therapy. The external beam radiation therapy (head and neck cancer) segment owns the highest market share and is estimated to exhibit a CAGR of 6.6% during the forecast period. EBRT mainly treats prostate, lung, breast, head and neck, and colorectal cancers. EBRT can treat inoperable patients suffering from colorectal and head and neck cancers. In addition, EBRT technologies are non-invasive, further increasing their adoption in cancer treatment. The high-impact-rendering market drivers are the ability to treat inoperable patients, deliver conformal doses, and increase awareness about the importance of early diagnosis.

Internal beam radiotherapy mainly treats breast, penile, prostate, cervical, and gynecologic cancers. Brachytherapy is most commonly used for treating prostate cancer. It is an excellent alternative to glossectomy in case of penile cancer. Internal beam radiotherapy offers high-tech and precise drug delivery. This therapy is also used to treat eye and gallbladder cancers. In addition, internal beam radiotherapy is a cost-effective option. The internal beam radiation therapy market is anticipated to expand at a lucrative rate due to the high prevalence of cancer in the region.
