Radiotherapy Market, by Product Type, Therapy Type, Application, End
User, and Region - Global Trends, and Forecast to 2025
Radiotherapy uses high-energy radiation beams such as gamma rays, x-rays, and protons to kill
cancerous cells by inhibiting growth and multiplication. Radiosurgery is often used before surgery
to reduce the size of a tumor prior to removal, or after surgery to destroy the cancerous cells left
behind. Various types of radiation therapies such as conformal radiotherapy (CRT), intensity
modulated radiotherapy (IMRT), image guided radiotherapy (IGRT), and 4-dimensional
radiotherapy are widely used to treat cancer. Internal radiotherapy is given using radioactive
material placed inside the body, while external beam radiotherapy delivers x-rays from outside the
body, using linear accelerators and other systems. The innovative image-guided radiotherapy is used
to integrate better imaging techniques for visualizing cancer tumor.

Market Dynamics
Major factors driving growth of the radiotherapy market include rising prevalence of cancer,
increasing adoption of innovative targeted therapies such as radiotherapy due to side effects
associated with traditional chemotherapies such as anemia and infection for cancer treatment.
According to the World Cancer Research Fund International, 2012, around 14.1 million cancer
cases were registered globally, the number of which is projected to rise to 24 million by 2035. This
in turn, is expected to increase the demand for radiotherapy over the forecast period. Nevertheless,
the opportunities for the key players to provide radiotherapy products in emerging markets with
increasing demand for efficacious cancer treatment are anticipated to provide better prospects for
market growth in the near future. However, difficulty in tumor visualization experienced during
radiotherapy procedures and the dearth of skilled professionals to carry out radiotherapy are factors
restraining growth of the radiotherapy market.
