MARKET DRIVERS

The growing cancer patient population worldwide is one of the major factors propelling the radiation oncology market growth. The number of people suffering from cancer is growing rapidly worldwide resulting in the increasing demand for radiation oncology services including radiation therapy and other related treatments. As per the data published by the International Agency for Research on Cancer (IARC), approximately 18.1 million new cancer cases and 9.6 million cancer deaths were recorded worldwide in 2018. The American Cancer Society says an estimated 1.9 million new cases were reported in the United States in 2022. As per the predictions of the Global Cancer Observatory (GCO), an estimated 29.5 million new cancer cases are predicted to record each year worldwide by 2040. Radiation therapy is a commonly used treatment procedure for cancer to destroy cancer cells using high-energy radiation. As the incidence of cancer grows, the demand for radiation oncology is expected to grow in the coming years.

Technological advancements have been contributing to the growth of the radiation oncology market and the trend is expected to continue in the coming years and favor the market growth. In recent years, technological advancements have played a key role in the development of advanced radiation therapies such as intensity-modulated radiation therapy (IMRT), image-guided radiation therapy (IGRT), and proton therapy. These therapies have been providing improved treatment outcomes and reduced side effects. The growing aging population worldwide is another major attribute boosting the growth rate of the radiation oncology market. People who are aged are more likely to develop cancer and the growing aging population is expected to boost the demand for radiation oncology services.

The rising demand for minimally invasive surgical procedures promotes the radiation oncology market growth. The awareness among the patient population regarding the benefits of minimally invasive surgeries such as smaller incisions, less scarring, increased accuracy, decreased risk of complications, shorter hospital stays, less pain and shorter recovery period has improved significantly in recent years. Due to this, the adoption and preference for minimally invasive surgeries have increased. Radiation therapy is a minimally invasive treatment option for cancer and has been widely adopted by the cancer patient population.

In addition, factors such as the growing awareness regarding the benefits of radiation therapy among the cancer patient population, the increasing number of initiatives by several governments for the R&D of cancer research and treatment to improve cancer care and reduce the burden of cancer and the rising number of cancer treatment facilities worldwide further boost the growth rate of the radiation oncology market. Furthermore, the growing healthcare spending, increasing number of advancements in imaging technology, rising preference for outpatient services due to convenience and flexibility to patients and growing prevalence of lifestyle diseases such as obesity and diabetes favor the growth rate of the radiation oncology market.

MARKET RESTRAINTS

High costs associated with the treatment costs of radiation therapy are one of the key factors hampering the market growth. Due to these high costs, accessibility and affordability are limited in developing countries. Poor reimbursement policies for radiation therapies are another significant obstacle to market growth. The scarcity of highly skilled and trained personnel including radiation oncologists, medical physicists, and radiation therapists, the side effects of radiation therapy such as fatigue, skin irritation and nausea, low awareness among patients and healthcare providers of the benefits of radiation therapy and the presence of alternative treatment modalities further hinder the market growth.
