Radiotherapy is a cornerstone in the multidisciplinary approach to cancer care. In 2012, the Global Task Force on Radiotherapy for Cancer Control estimated that, if all patients with cancer with an evidence-based indication for radiotherapy worldwide had access to radiotherapy, more than 580 000 patients would be cured each year, amounting to 1 million by 2035.1 These figures pertain to the global cancer population, including patients that receive palliative radiotherapy, for whom long-term benefits are not anticipated, and even those for whom radiotherapy is not indicated.
