title: Unexpected breast cancer detection after outpatient biopsy for benign lesion.
abstract: At the Istituto Nazionale Tumori of Milan, in its Outpatient Department, 1302 breast surgical biopsies were carried out in 1978. Fibroadenomas occurred in 44.2% and benign dysplasias in 39.3%. Sixty-two cancers (4.8%) and 23 atypical hyperplasias (1.8%) were unexpected findings, with an increasing incidence in women over 50. Seventy-nine duct resections were performed for significant nipple discharge and revealed 5 unexpected carcinomas and 28 papillomas or papillomatosis. In our opinion and experience, this procedure of performing breast biopsy in the presence of a solid lump in women over 30 without hospitalization improves early detection of cancer, lowers costs, cuts down admission waiting lists and increases the number of women who better accept a surgical diagnosis and treatment.
