Nuclear Explained

With more than 19 million new cases and 10 million deaths in 2020 alone, the global annual cancer burden is expected to grow. Radiotherapy is one of the most widely used therapies for cancer treatment. With radiotherapy, nuclear radiation, also known as ionizing radiation, is applied to harm and destroy cancer tumour cells. In this episode, health experts talk about the different forms of radiotherapy and what it takes to provide this lifesaving treatment.


  • Verna Vanderpuye, Clinical Oncologist at the National Center for Radiotherapy and Nuclear Medicine in Accra, Ghana
  • Lisbeth Cordero Mendez, Radiation Oncologist at the IAEA
  • Tarek Shouman, Professor of Radiation Oncology at the National Cancer Institute at Cairo University

The role of radiotherapy in treating cancer will be discussed at the IAEA's Scientific Forum on Rays of Hope: Cancer Care for All from 27 to 28 September, during the 66th Annual IAEA General Conference. The Scientific Forum will be livestreamed.
