Abstract: |
One of the most challenging developments in clinical oncology is the availability of testing for inherited mutations of cancer predisposition genes. As these genes were identified and characterized, guidelines for the responsible clinical translation of this information were developed by medical and surgical subspecialty societies (e.g., Statement of the American Society of Clinical Oncology, 1996). Each guideline emphasized that in the process of offering a predictive genetic 'test' to a patient or family affected by cancer, the provider and the individual being tested must be prepared to deal with all the medical, psychological, and social consequences of a positive, negative, or ambiguous result. This presentation focuses on the genetics of breast cancer predisposition. AH genetic testing, however, must be offered in the context of informed consent, reviewed elsewhere (1). |
