ABSTRACT
Radiotherapy has been used in the management of cancer since the turn of the twentieth century, and continues to have a very important role in the twenty-first century. X-rays were first discovered in 1895. The first reported cure of a malignant tumour using radiotherapy was reported in 1899.1 A patient with a histologically confirmed basal cell carcinoma of the nose was treated with 150 radiations over 9 months. She was cured and alive and well 30 years later. The International Commission on Radiation Units and Measurements (ICRU) was formed in 1925 recognizing that it was essential to define and measure the delivery of radiotherapy.
