A total of 1315 breast lesions seen in women up to 40 years of age were registered in the files of Pathology Department. Out of these 807 were benign and 508 malignant lesions. Breast carcinoma was very rare up to second decade of life but its incidence progressively increased with age. Among benign tumours fibroadenomas were the commonest tumours. This study shows a higher incidence of inflammatory diseases and malignant tumours in young females as compared to the reports from the West.
