Operable carcinoma occurring simultaneously in both breasts at the time of the first examination is an uncommon clinical entity. Reference to it, however, was made by Nisbet,1 in 1800, and since that time its presence has been noted frequently in most large series. Davis,2 in 1919, alluded to it while reporting to this Association his operative experience with 166 breast cancers. Considerable interest was manifested shortly thereafter in the entire problem of bilateral breast carcinoma by Kilgore,3 Greenough,* and McWilliams.4 The very inclusive tabulations of Lewis and Rienhoff5 and of Harrington6 have established a firm statistical baseline for further studies. These six reports include a total of more than 12,000 patients of whom approximately 1% presented operable bilateral breast cancer at the time of the first visit.
In view of the apparent increase in incidence of breast cancer, a continuing interest is noted in
