[Counselling, genetic testing and prevention in women with hereditary breast- and ovarian cancer. Interdisciplinary recommendations of the consortium "Hereditary Breast- and Ovarian Cancer" of the German Cancer AiD].

Women with familial predisposition for breast and ovarian cancer represent a small group of patients with very high risk for developing breast and/ or ovarian cancer before the age of 50 years. The individual breast cancer risk can be assessed by genetic counselling and can be specified by genetic diagnostics. As part of the gynaecological consultation, adequate preventive measures are offered. Psycho-oncological counselling may help in decision making. For hereditary carcinomas, counselling is still not considered as a routine medical care, even though basic and routine preventive measures are insufficient for this group of high risk patients. Within the last years, 12 specialized centres in Germany have developed a patient care concept for women with a familial risk for breast and ovarian cancer. Establishment of these centres for familial breast and ovarian cancer and use of evidence-based medical care was initiated in a nationwide interdisciplinary joint research project and supported by the German Cancer AiD. These measures were integrated in a quality assurance concept for structure, process and result optimization. Thus, all requirements for introducing these services into routine patient management have been fulfilled.
