Improvement of the results of treatment was achieved only when an increased number of patients were diagnosed in stage I. The prerequisite for limitation of radical surgery is histomorphologic classification of the stages. The central axillary group of lymph nodes appears to be representative of lymph node involvement.

In histologic stage I, modified radical mastectomy; is the treatment of choices; operations with further limitations are recommended only within the scope of controlled studies. In stage II, the classical ablation is still the safest procedure.
