abstract: The incidence of small breast carcinoma especially of non-palpable lesion is increasing after introduction of mammography screening. The tumor of which diameter is less than 2 cm, non invasive carcinoma, and Paget's disease are included in early stage of breast cancer. This article introduces the rate of early stage breast cancer in the mammography screening and the feature of these mammographic findings.
