Data of patients found to have bilateral breast cancer (BBC) was analyzed focusing on the demographic information, family history, menstrual status, surgical therapy, staging and histopathological characteristics.

RESULTS:

Of patients 215 treated for breast cancer 19 (8, 8%) revealed metachronous BBC. The median age was 57, 7 (ranges, 36-77) years. For patients with metachronous breast carcinomas, the median interval between the fi rst and second diagnosis was 8 (ranges, 3-15) years. Six patients with metachronous of them (31,5%) were in postmenopousal, and 13 of them (68, 5%) in premenopousal status. One of metachronous patient revealed positive family history. For metachronous patients, 5, 4, 3, 4 and 3 having stages I, IIA, IIB, IIIA, and IV disease, respectively. The most common type of breast cancer recorded was invasive ductal carcinoma.
