Nine Cases of Bilateral Breast Cancer

154 patients with breast cancer were treated at our department from January 1981 to December 1990, 9 of which had bilateral involvement. Two patients had synchronous primary cancer, 5 had metachronous primary cancer and 2 had metachronous metastatic cancer. The second cencer was usually detested through self examination by patients and presented at an earlier stage than the primary cancer in our series. Since bilateral breast cancer in not uncommon, patients will require close fllow up after their initial cancer had been treated. Any suspocious masses should be biopsied. Diagnosis of a second primary versus metastatic cancer is made based on histological and clinical criteria.
