Background: To evaluate the frequency and time of presentation of benign and malignant breast lumps among pregnant females. Methods: In this descriptive study all pregnant females with a complaint of lump in breast were included . Triple assessment was done for each patient (examination of lump, ultrasound for patients under 40 years, mammography for those above 40 years and fine needle aspiration cytology). Results: Out of 78 pregnant females, with complaints of breast lump, 47 (60.25%) were found to have breast lumps and 31 (38.75%) had pregnancy induced changes. Majority of the patients (85.1%) had benign breast disease. Out of seven patients (14.9%) with malignant breast disease, three (4.3%) were primigravidas as compared to patients with benign breast disorders where only 6 out of 40 cases (15%) were primigravidas. Mean age of patients with benign breast disease was 27 years (range 15-40 years) and mean age of those with malignant lumps was 35 years( range 29-43 years). Approximately 51% of all lumps presented during first and second trimester and rest during third trimester . On histopathological examination all malignant lumps proved to be intraductal carcinomas. Conclusion: The incidence of breast lumps during pregnancy is slightly higher (14.9%) than in non-pregnant females although majority of breast lumps during pregnancy are benign.
