DATA SYNTHESIS: A description of the availability of genetic counseling, of motivation for undergoing genetic counseling, and of the basic components of genetic counseling for cancer. CONCLUSIONS: The need for genetic counseling will increase as more families with inherited cancer are identified, more cancer genes are isolated, and genetic analysis becomes more available. IMPLICATIONS FOR NURSING PRACTICE: Advances in genetic technology provide nurses with the opportunity for an expanded role in genetic counseling for cancer. Oncology nurses also can act as case finders of families with inherited cancers and conduct research in this area.
