Researchers and practitioners can use inductively derived theory to direct their research and practice. This article describes the ongoing development of a theory that can assist in explaining experiences of young women with breast cancer who have genetic testing for the BRCA mutation. Seventeen BRCA-negative women with breast cancer from a larger grounded theory study were interviewed. While receiving a negative BRCA mutation test result subsequent to a breast cancer diagnosis was described as a relief, the information was also confusing. The author's published Theory of Genetic Vulnerability is expanded to incorporate the outcomes of this analysis.
