Individuals living in geographically underserved areas encounter considerable barriers to access of quality cancer genetic services. Although in-person genetic counseling has generally been accepted as the standard of care, the use of telecommunications to deliver clinical genetic services may help reduce this disparity in access to such services. However, before the widespread adoption of telephone-delivered cancer genetic services occurs, it is critical to analyze the efficacy and safety of this mode of communication. This two-group randomized equivalency/non-inferiority trial will determine whether telephone-based cancer genetic counseling is an acceptable alternative to the traditional in-person mode among women who have a personal or family history of breast and/or ovarian cancer strong enough to warrant genetic counseling and testing. This study's findings will provide important information to cancer centers and cancer control policies about the safety, efficacy, and costs of delivering telephone-based clinical cancer genetic services for geographically challenged women at risk for having Breast Cancer susceptibility gene (BRCA) 1/2 mutations.
