Radiotherapist Kofi Kyei, 30, points at a tumour on an x-ray from a patient suffering from bladder cancer at the Korle Bu Teaching Hospital in Accra April 24, 2012. Most of Africa's around 2,000 languages have no word for cancer. The common perception in both developing and developed countries is that it's a disease of the wealthy world, where high-fat, processed-food diets, alcohol, smoking and sedentary lifestyles fuel tumour growth. Yet there are an estimated one million new cancer cases sub-Saharan Africa will see this year - a number predicted to double to 2 million a year in the next decade. Picture taken April 24, 2012.
