Poverty as well as lack of proper cancer programmes has prevented the early detection of cancer in developing countries. Radiotherapy is applied mostly in advanced cases only. To change the situation comprehensive programmes must be introduced with particular attention to the importance of cancer control. The establishment of cancer societies as well as the introduction of centres for training of radiological personnel will really improve the situation. A realistic method for the optimization of radiotherapy in developing countries should be the use of radiomodification such as hypoxyradiotherapy.
