The growing cancer patient population worldwide is driving the radiotherapy market growth.

The need for radiotherapy services is growing significantly due to the growing prevalence of cancer. According to the data published by the World Health Organization (WHO), cancer is one of the leading causes of mortalities worldwide and an estimated 10 million deaths were due to cancer in 2020. In the United States, an estimated 1.9 million new cancer cases were recorded in 2021 and this number is gradually over the last ten years. The American Cancer Society predicts that an estimated 27.5 new million cancer cases are expected to report annually by 2040 due to the growing aging population. According to International Atomic Energy Agency (IAEA), radiotherapy is an effective treatment option for cancer and a widely adopted treatment option for cancer in developing countries. In recent years, radiotherapy has experienced several technological developments and resulting in the increasing usage of radiotherapy for cancer treatment. For instance, intensity-modulated radiation therapy (IMRT) and image-guided radiation therapy (IGRT) have gained popularity for their improved treatment accuracy and reduced side effects. Other than traditional external beam radiotherapy, radiotherapies such as brachytherapy and proton therapy have become effective treatment options for cancer treatment in recent years.

Increasing demand for radiation therapy in emerging economies is promoting the radiotherapy market growth.

As per the data published by the International Atomic Energy Agency (IAEA), an estimated 60% of cancer deaths occur in underdeveloped and developing countries and at the same time, these countries have a significant shortage of radiotherapy facilities and have become a significant opportunity for the market participants to capture the untapped market potential. WHO says underdeveloped and developing countries have access to only a 5% of the world's equipment for radiotherapy. As a result, governmental organizations and key market participants have been focusing on developing radiotherapy treatment services in emerging economies. In addition, the adoption of modern radiotherapy therapy technologies in emerging economies has also increased in recent years and contributed to market growth. For instance, the availability and adoption of modern radiotherapy therapy technologies such as intensity-modulated radiation therapy (IMRT) and image-guided radiation therapy (IGRT) have increased notably in emerging economies such as India, China, and Brazil.

Rising healthcare expenditure and growing funding by governments for cancer treatment are propelling the radiotherapy market growth.

The governments of various countries have been increasing their expenditure to develop effective treatment options for cancer, including radiotherapy. For instance, the National Cancer Institute in the United States has increased its budget significantly in the last 10 years. Similarly, the NHS increased its Cancer Drugs Fund from 280 million Euros for 2014/15 to 340 million Euros for 2015/16 to use for radiotherapy, cancer diagnoses, cancer surgery, and other important NHS services for other patient groups.

In addition, the increasing number of advancements in radiotherapy technology, rising preference for non-invasive cancer treatments, and increasing awareness regarding the benefits of radiotherapy among people and healthcare providers are contributing to the growth of the radiotherapy market. Furthermore, factors such as technological innovations in imaging and radiation delivery systems, rapid adoption of intensity-modulated radiation therapy (IMRT) and image-guided radiation therapy (IGRT) techniques, growing usage of proton therapy for cancer treatment, and the growing number of cancer treatment facilities and radiation oncologists are fuelling the growth rate of the radiotherapy market. In addition, the growing number of clinical trials for radiotherapy and rising usage of combination therapies involving radiotherapy, increasing integration of radiotherapy with other treatment modalities like chemotherapy and surgery, development of new radiotherapy drugs and pharmaceuticals, increasing usage of brachytherapy for internal radiation therapy and rising adoption of artificial intelligence and machine learning in radiotherapy treatment planning and delivery are other notable factors supporting the growth of the radiotherapy market.

Market Restraints:

On the other side, the high costs associated with radiotherapy treatments are unaffordable to many patients, limiting the adoption of these treatments and hampering the market’s growth rate. The availability and accessibility of radiotherapy services are limited in many underdeveloped and developing countries, diluting the global market's growth rate. The scarcity of skilled healthcare professionals such as radiation oncologists, medical physicists, and radiation therapists is limiting the availability of radiotherapy services in many countries and negatively affecting the overall market’s growth rate. Side effects and complications associated with using radiotherapy are further hindering the radiotherapy market growth. In addition, the availability of alternative treatment options for cancer is impeding the market growth slightly. The lack of specialized equipment and infrastructure required to provide radiotherapy services in some countries and poor awareness among patients and healthcare providers regarding the benefits of radiotherapy are showcasing a negative impact on the growth rate of the radiotherapy market.

Impact of COVID-19 on the global radiotherapy market:

COVID-19 was announced as the emergence of healthcare by the world health organization. The radiotherapy market had a downfall in the initial months of 2020 because all the treatment activities had been postponed or canceled. Several hospitals were shut down during this period, and some were converted to COVID-19 care centers. However, the unlock guidelines by the government in almost every country have positively affected the radiotherapy market. All the activities were resumed by taking preventive measures. It is mandatory to follow the strict guidelines in the hospitals as cancer patients may have adverse effects due to COVID-19 once infected. Many cancer patients infected with the coronavirus have lost their lives even after having advanced treatment procedures. By 2021, the market shares are expected to enter the normal state.
