• An analysis of 1,686 surgically treated carcinomas of the breast in one community showed no statistically significant differences in five-and ten-year survival for simple, modified radical, or radical mastectomy. Further confirmation was obtained by computation of relative survival which in addition showed that older women more nearly approach normal life expectancy than younger ones.
Bilaterality was found to be a decreasing function of age. Patients with medial and lateral tumors did not have significantly different rates of survival or sites of distant metastases.
