Abstract
Objectives To review cancer risk assessment and counseling, hereditary cancer syndrome risk factors, indicators for cancer predisposition testing, and interpretation of genetic test results. Data sources Research studies, review articles, and authors’ experience. Conclusion Approximately 10% of those with a diagnosis of cancer may have a hereditary predisposition. In many cases genetic testing for susceptibility genes may be available. Knowledge of the results of genetic testing can be helpful when developing a plan for cancer prevention and early detection, and addressing concerns associated with genetic testing with the individual and family. Implications for nursing practice Nurses need to know how to access genetic resources and to identify, evaluate, and care for patients and families at risk of or diagnosed with common hereditary cancer syndromes.
