The risk of ipsilateral failure is much lower than the risk of a new tumor in the contralateral breast. It is heartening that none of the patients in the series had, and the authors do not recommend, bilateral mastectomy for DCIS.

The 7% incidence of local recurrence in patients treated with lumpectomy and radiation therapy is significantly lower than the reported incidence of local recurrence in infiltrating ductal carcinoma treated in a similar manner. Hence, there is no basis for the authors' comment that "Intraductal carcinomas
