An evaluation of bilateral breast carcinoma. Simultaneous and sequential lesions.
The detection of bilateral breast carcinoma, simultaneous or nonsimultaneous, appears to be increasing. Undoubtedly a major factor in this is the increased use of mammography and xeromammography. In a 21-year period at Saint John's Hospital and Health Center, 1,189 cases of primary breast carcinoma were treated, of which 34 (2.9 percent) were bilateral. However, from 1972 to 1974 the incidence has risen from 1.9 to 10.8 percent, with a simultaneous rise in numbers of xeromammograms made. Xeromammography should be done routinely in patients in whom carcinoma of the breast is suspected. Its use should also be an integral part of the follow-up in patients in whom mastectomy has been carried out previously.
