Four hundred and twenty five breast carcinomas diagnosed in female Black patients constitute the material of this study. Most tumours were seen between the ages of 40 and 49 years with another peak seen in the seventh decade. The commonest histological tumour type was an infiltrating ductal carcinoma (NOS), constituting 90.4 pc of all the tumours. Twenty five tumours (5.9 pc) had mucinous histological appearance. There were only four (0.9 pc), intraductal carcinomas. Fifty three pc of all the tumours had a high grade histology (grade III).
