Clinics in diagnostic imaging (11). Ductal carcinoma of the breast.

A 39-year-old Chinese woman presented with a palpable breast lump which was increasing in size. No overlying skin change or axillary lymph nodes were palpable. Mammograms and ultrasound showed a malignant left breast lesion, suspicious of ductal carcinoma. Following excision biopsy which confirmed infiltrative ductal carcinoma, a left modified radical mastectomy was performed. The role of mammographic screening is discussed. Diagnostic mammography in conjunction with ultrasound is emphasised.
