In 2011, the four longer established cancer registries (Nairobi, Blantyre, Kampala and Harare) conducted work to record  stage at diagnosis of cases registered in 2010 (for breast and cervix cancer), and survival for these two cancers plus cancers of the oesophagus and prostate (the most common cancers of men in the region). The target was to follow up a random sample of 100 cases of each of these cancers, diagnosed in the period 2004-2008, until the end of 2010.
