Breast cancer is a worldwide problem but its frequency varied from place to place. One hundred twenty-four breast cancer cases were reported during the ten years of survey at Aligarh constituting 12.4% of all malignant lesions. Peak incidence was found between the age of 41 and 50 years. More patients were from lower socio-economic group belonging to both Hindu as well as Muslim communities. Nearly 90% of cases had their menarche by the age of 14 years. Male breast cancer was 4%. Right breast was more commonly affected than that of the left. The upper and outer quadrant was involved in more than one-third cases and more than half the lesions occurred in upper half. There were 97.6% of epithelial and 2.4% of stromal tumours. Among epithelial tumours, highest incidence (72.38%) was that of invasive duct carcinoma followed by medullary, colloid and Paget's disease.
