Bilateral breast carcinoma: clinical characteristics and its impact on survival.

The higher incidence of breast cancer, the improvements in diagnosis and treatment, together with the growing life expectancy have brought about an increase in the number of patients at risk for bilateral breast carcinoma. The aim of this study is to describe the characteristics of patients suffering from bilateral breast carcinoma who underwent surgery at the Breast Pathology Service of the Buenos Aires British Hospital and to analyze impact on survival. Between January 1970 and May 2007, 4,085 cases of breast carcinoma in 3,864 patients were treated at the Breast Diseases Division of the Buenos Aires British Hospital.
