[Breast cancer in Sub-Saharan African women: review]

Breast cancer is the second most frequent cancer in Sub-Saharan African women with an incidence of 15-53 per 100,000 women. Using PubMed, we reviewed all the articles published on this topic between 1989 and 2009. Breast cancer is usually diagnosed in women younger than in developed countries (mean age: 42-53 years), with later stages (III or IV, i.e. with axillary nodes and distant metastases). Reported tumors are mostly invasive ductal carcinomas with aggressive characteristics: grade III histoprognosis, absence of hormonal receptors or HER2 expression. According to the new breast cancer classification, nearly half of these tumors should be classified as triple negative. However, studies are rare and require confirmation. In conclusion, data on epidemiology and biology of breast cancer in Sub-Saharan African women are still scarce and need more extensive studies. In these countries, the pattern of breast cancer will likely change in the future, according to the evolution of lifestyle namely urbanisation. There is a great need for commitment of research and clinical resources in Sub-Saharan Africa in order to develop specific strategies.
