A family history of breast cancer: women's experiences from a theoretical perspective.

Individuals at increased risk of developing breast cancer due to their family history of the disease face a number of uncertainties. Personal cancer risk estimates are imprecise and current methods for early detection or prevention are not 100% effective. It is therefore not surprising that adverse psychosocial outcomes have been described within this population. Research attempting to predict the incidence of distress and dysfunction in individuals at increased risk of cancer has been largely a-theoretical and has overlooked a number of potentially important predictive variables. In particular, the influence of personal experience of cancer through involvement with affected relatives has been neglected. There are strong theoretical grounds for hypothesising that dimensions of personal experience may influence response to cancer risk. This paper discusses the potential impact of personal experience on risk perception, illness representations and decision-making. Systematic research in this area may improve predictions of outcome of cancer genetic counselling and inform the clinical process.
