Abstract

Purpose:Women carrying BRCA1/BRCA2 germ-line mutations have an increased risk of developing breast/ovarian cancer. To minimize this risk, international guidelines recommend lifelong surveillance and preventive measures. This study explores the challenges that unaffected women genetically predisposed to breast/ovarian cancer face in managing their risk over time and the psychosocial processes behind these challenges.Methods:Between 2011 and 2013, biographical qualitative interviews were conducted in Switzerland with 32 unaffected French- and Italian-speaking women carrying BRCA1/BRCA2 mutations. Their mutation status had been known for at least 3 years (mean, 6 years). Data were analyzed through constant comparative analysis using software for qualitative analysis.Results:From the time these women received their positive genetic test results, they were encouraged to follow medical guidelines. Meanwhile, their adherence to these guidelines was constantly questioned by their social and medical environments. As a result of these contradictory pressures, BRCA1/BRCA2 mutation carriers experienced a sense of disorientation about the most appropriate way of dealing with genetic risk.Conclusion:Given the contradictory attitudes of health-care professionals in caring for unaffected BRCA1/BRCA2 mutation carriers, there is an urgent need to educate physicians in dealing with genetically at-risk women and to promote a shared representation of this condition among them.Genet Med advance online publication 11 December 2014Genetics in Medicine (2014); doi:10.1038/gim.2014.183.
