[Cancer in Africa, a new health challenge. Examples of Mali and OncoMali]

Oncology is perceived as a secondary problem of public health in emerging countries. Nevertheless the annual incidence of cancers is rapidly expanding (approximately 100 to 120/100 000 subsaharan Africa). It can explain by the high incidence of the infectious pathologies associated with a high oncogene risk (hepatitis, HIV, Helicobacter ...) but also by national and international prevention policies still too much reduced. If this epidemiological tendency continues, Africa will count in 2020 near a million new cases of cancers every year. The incidence increases but the morbi-mortality is also very high in these countries. This observation exceeds the simple consequence of a defect of means. The sociocultural landscape and the mental representations of this disease are also in cause. We shall evoke in this article the situation of Africa by quoting the example of Mali. We shall conclude on the individual contributions which can be made through the example of the association "OncoMali".
