Brief description Systematic review of the literature on psychosocial predictors of developing breast cancer has highlighted the possible roles of life events and distress, possibly mediated by social support and personality. To date there has been little prospective assessment of psychosocial factors in the development of breast cancer. Furthermore, no research in this area has specifically targeted women at increased risk because of their family history, nor explored whether the impact of psychosocial factors systematically varies according to genetic mutation status. Over the past 5 years it has become possible to isolate two breast cancer genes (BRCA1 and BRCA2). Female carriers of mutations in these susceptibility genes have an estimated lifetime risk of breast cancer of between 37% and 85%. The Kathleen Cuningham Consortium for Research into Familial Breast Cancer (KConFab) was established four years ago to co-ordinate the collection of genetic, epidemiological and clinical data in Australian families with a dominantly inherited predisposition to breast cancer. The systematic recruitment of large numbers of high risk women by KConFab provides a unique and temporary opportunity to address questions concerning psychosocial predictors of disease development in a prospective design with sufficient power, due to the higher rates of breast and ovarian cancer events in this population. We will also be able to explore interactions with genetic mutation status. The study will be a world first, and provide the most rigorous data to date in this area. If this study demonstrates a relationship between psychosocial factors and the development of breast cancer in women from high risk families, subsequent identification of vulnerable individuals and the implementation of appropriate interventions may have a real impact on reducing morbidity and mortality in this population. Furthermore, the results may have implications for all women in reducing breast cancer incidence.
