Breast biopsy and the surgical treatment of early carcinoma of the breast.

Biopsy techniques include aspiration for fluid, for cytology, or for histology. The indications for each method depend on the physical and/or mammographic findings. If a breast cancer is diagnosed, then treatment will depend on the size and location of the lesion and the patient's wishes. The surgical technique for lumpectomy and axillary node dissection is described.
