Decision-making Regarding Prophylactic Mastectomy and Oophorectomy in Women Seeking Genetic Counseling and Testing for BRCA1/2 Mutations

Memorial Sloan Kettering Cancer Center224 enrolled

Overview

The purpose of this study is to learn more about women's decision to undergo prophylactic surgery. This is removal of healthy organs in order to reduce risk of cancer. This study will help us to understand what makes women decide whether or not to have this kind of surgery.

For women with a strong family history of breast/ovarian cancer, few options exist for primary prevention of these cancers other than prophylactic surgery, or surgical removal of noncancerous organs in order to prevent occurrence of the disease. The primary aim of the study is to describe the stages of intention to undergo prophylactic mastectomy and/or oophorectomy among women seeking genetic testing for inherited BRCA1 and BRCA2 mutations, and to identify factors that influence stages of intention regarding prophylactic surgery. To achieve these aims, 626 women undergoing genetic counseling and testing for inherited breast ovarian cancer risk will be assessed before their first genetic counseling session and three times (1 week, 6 months and 12 months) in the year following notification of their genetic test results.
