[Histological margin and residual disease assessment for breast carcinoma]. / Evaluation des limites d'exérèse chirurgicale en pathologie mammaire. Risque de maladie résiduelle.

Their evaluation requires standardized pathological analysis. These factors should be interpreted in clinical and radiological context.
