title: Factors associated with oesophageal cancer in Soweto, South Africa.
abstract: Cancer of the oesophagus was a rare disease in the South African black population until the last few decades. Increases in incidence have occurred and at present it is the commonest cancer in black men in many parts of South Africa. A case-control study of 200 oesophageal cancer patients and 391 hospital controls has been carried out in order to determine the risk factors in the urban black population of Soweto. The results indicate that the cancer patients were long-term urban residents from a very low socio-economic group. The association between smoking pipe tobacco and oesophageal cancer previously noted in South Africa is confirmed. In addition, consumption of traditional beer was found to be a major risk factor.
