Norwegian health care for women at risk of inherited breast cancer conforms with the European consensus guidelines published in 1999 and the Norwegian legislation regulating the use of predictive genetic testing. This paper represents a consensus between all medical genetic institutions in Norway handling inherited breast cancer through the Norwegian Group on Inherited Cancer. It is an update based on new knowledge, the structure of our health service and locally available technology and health care resources. The indications for referring patients to genetic testing are maintained. The demonstration of local founder BRCA1 mutations has been used to develop a high capacity for testing for these mutations. Mutation carriers should be offered annual MRI of the breasts for early diagnosis. Oophorectomy at end of childbearing ages is advocated in BRCA mutation carriers and breast-ovarian kindreds. The clinical geneticists have the role of coordinating health service to those in need, and are required to collaborate to present the empirical results of the effects of the interventions.
