Abstract
IN East Africa, certain rare tumours, oesophageal, nasopharyngeal, liver, Burkitt lymphomas and the like, are concentrated in distinct localized pockets1. The reason for this and the aetiology of these tumours are not known. More than one factor may be involved. Such agents as viruses, or microbial toxins present in food, however, are not easy to avoid. Is there some relation between these tumours and the plants that grow locally and are eaten as food or as medicine?
