[Biopsy of occult lesions detected by mammography in a district hospital].
Most series of biopsies of mammographically identified breast lesions are performed in specialized units following mass screening and report an 11% to 36% rate of carcinoma. The results of such biopsies in a district hospital setting are analysed. Seventy-nine consecutive needle localisation biopsies were performed over a 2.5-year period by 15 surgeons and retrospectively reviewed. 13 lesions (16%) were referred by the National Breast Screening Programme. Carcinomas were found on 24 biopsies (30%): 8 were in situ and 16 were infiltrative, 5 of whom were less than 0.5 cm. Thus half of them met the criteria of "minimal" carcinoma as described by GALLAGHER. 40% of women 50 years and older and 13% of women less than 50 years had carcinoma. 6% of the lesions read on mammogram as "probably" benign and 47% of those considered as "probably" malignant were cancer. There was no significant correlation between the mammographic appearance and the occurrence of cancer but all "minimal" invasive carcinomas were associated with calcifications. Complete removal of the lesion failed in 3 cases. Localisation biopsy can be performed in a district hospital by general surgeons with a similar yield of malignancies as in specialized unit and with a high incidence of early detected cancers.
