The Pattern of Breast Diseases at Kenyatta National Hospital

Results: An average 469 new patients per year or 11 new patients per clinic visit were reviewed over a two and a half year period. Females predominated (98.9%). The mean age of the patients was 34.71 years (range 1 to 96 years). The average age at menarche was 14.49 years and the mean duration of symptoms was 6.86 months. Only 2.6% of 843 patients had a positive family history of breast disease. Fibroadenoma was the commonest diagnosis made (33.2%) followed by ductal carcinoma (19.7%). Gynaecomastia was the most common lesion seen in males. Two thirds of patients presenting with lumps had masses measuring more than 5cm. Overall, five conditions (fibroadenoma, ductal carcinoma, breast abscesses, fibrocystic disease and mastalgia) accounted for over 85% of all breast ailments. Surgery formed the mainstay of care in over 80% of patients.
