[Treatment of breast cancer (author's transl)].

Controlled trials and long term studies in patients with breast cancer of stage I and II have shown, that this disease in the majority of cases is no longer localized when first noticed clinically. Surgical therapy is therefore only a part of the complete management of these patients and must be thought over concerning its radicality. In England several controlled studies are under way for that reason. They are conducted and continuously evaluated by multidisciplinary teams of which the surgeon is an important member.
