title: [Genetics of breast cancer].
abstract: Breast cancer has generally environmental causes. However numerous investigations among the families of cancer patients have shown the probable role of a genetic factor in a minority of the cases. Those cases are characterized by the early age of the patient, the multicentricity of the tumour and the frequent association with other neoplasms. Progress in molecular genetics should allow in the next future the discovery in the population of high risk subjects.
