Abstract: | Individuals who seek genetic testing to determine hereditary risk of breast cancer may not be aware that genetic testing is uninformative in many high-risk families or that they may be at increased risk of other cancers as well. Many mistakenly believe that current genetic testing provides definitive information about the magnitude of cancer risk to carriers. This article describes the assessment of hereditary risk by pedigree analysis, epidemiology, and genetic testing within the cancer risk assessment and counseling setting, and discusses other information that helps patients to make informed health care decisions. Because the risk of ovarian cancer is increased in many families at high risk of breast cancer, information about prophylactic oophorectomy and hormone replacement therapy is essential. A case history is presented to show the efficacy of cancer risk assessment and counseling when genetic testing is uninformative. ? |
