title: Clinical patterns of presentation of breast cancer in women of different racial groups in South Africa.
abstract: The ages at presentation of white patients with breast cancer were found to be significantly higher than those of blacks, Indians and coloureds; 73% of white women fell into the postmenopausal group, in marked contrast to only 35% of Indians, while blacks and coloureds had similar proportions of pre- and post-menopausal patients. A significantly higher incidence of poorly differentiated tumours was seen in Indian and black patients. Blacks showed a significant tendency to present with more advanced disease, while whites were generally diagnosed at a much earlier stage.
