Abstract

Increased awareness of benefits of early detection of breast cancer has resulted in increased numbers of screening mammographies and breast biopsies for nonpalpable lesions. Tertiary hospital studies have demonstrated positive biopsy rates from abnormal mammographic findings at 18 to 32 per cent. We examined the effectiveness of needle biopsy for nonpalpable radiographic abnormalities in our community hospital. We reviewed 167 records of patients biopsied over a 2-year period. Mammographic assessment, biopsy, and pathological assessment were performed using accepted methods. Malignancy was detected in 34 of 167 biopsies (20%). The biopsy yield rate was highest for mammographic findings of spiculated or stellate masses (75%, P < 0.01). Most biopsies (83%) were performed because of mammographic findings of microcalcifications or circumscribed enlarging masses/nodular developing densities for a positive biopsy yield rate of 16 per cent. Rates were higher in patients with personal (44%) or family history (30%) of breast cancer and in postmenopausal women (30%). These results demonstrate that 1) factors such as age, personal or family history of breast cancer, and certain mammographic features of breast lesions are associated with high biopsy yield rates, and 2) the biopsy yield rate in our community setting is comparable to tertiary hospital experience.
