Screening tumors of breast are detected by instrumental methods of diagnosis, such as mammography (MG), ultrasonography (USG) and magnetic resonance imaging (MRI) only; typically have a size to 2.0 cm (T1) and need support (MG or USG control) at biopsy for morphological study. In the present study the clinical symptoms were analyzed using a large clinical data (1,347 patients with stage-I breast cancer), the rate of screening tumors and the possibility of pre-surgical biopsy of these tumors. The proportion of screening cancer, identified by instrumental methods of diagnosis was only 12.8%, which means the insufficient level of screening programs for all age groups women.
