Diagnostic tests are now available that allow genetic testing for several types of cancer. The aim of genetic counseling and testing for cancer is to educate individuals about cancer risk and cancer prevention, which it is hoped will lead to a reduction in morbidity and mortality. However, at this relatively early stage in the development of genetic counseling and testing programs, information is needed on the psychosocial impact of such programs on both the individual counselee and his/her family. This paper reviews the findings obtained during the past decade on the uptake of genetic testing, reasons for undergoing genetic testing, and the impact of genetic counseling and testing on feelings of distress and guilt. Specific attention is paid to experiences with prophylactic mastectomy and oophorectomy and the effectiveness of the uptake of and satisfaction with these risk-reducing procedures. In addition, the possible impact of genetic testing on insurance, work and future plans is discussed. Suggestions are given for translating research findings into psychosocial services and future research efforts.
