The impact of genetic screening on surgical decision-making in breast cancer.
For centuries, clinicians have recognized that a segment of their patient population is at increased risk to
develop breast cancer based on their family history of the disease. Due to the absence of molecular
information, it was not uncommon for women and their surgeons to make decisions regarding management
of prophylactic surgery based solely on their family history, without specific information about the
patient's personal risk to develop the disease. It has been only within the past 7 years that linkage for the
breast cancer (BRCA) susceptibility genes has been established, and within the past 3 years that the genes
have been cloned. Although clinical testing for the BRCA genes has been available for less than 2 years, it is
already apparent that the implications for surgeons and their patients are significant.
