Swiss primary care physicians' knowledge, attitudes and perception towards genetic testing for hereditary breast cancer.

Purpose: The Swiss Institute for Applied Cancer Research's (SIAK) Network for Cancer Predisposition Testing and Counseling was established in 1999. To define its role in the care of individuals with inherited cancer predisposition, attitudes, knowledge and perception of primary care physicians towards genetic counseling and testing for hereditary breast cancer were examined.

Methods: A questionnaire was sent to 1391 primary care physicians in private practice in the German-speaking Canton of Zürich.
