Partial mastectomy without radiation therapy.

Partial mastectomy without radiation therapy has been used at The Cleveland Clinic as a treatment option for selected patients with breast cancer since 1957. Our experience with 322 patients has been reviewed; survival results are equal to or better than the other operative procedures we have employed for the treatment of breast cancer. These results, we believe, relate more to the selection of patients with small tumors and at a more favorable stage of the disease than to the benefit of the operative procedure itself.
