The prevalence of BRCA1 mutations among young women with triple-negative breast cancer.

Background: Molecular screening for BRCA1 and BRCA2 mutations is now an established component of risk evaluation and management of familial breast cancer. Features of hereditary breast cancer include an early age-of-onset and over-representation of the 'triple-negative' phenotype (negative for estrogen-receptor, progesterone-receptor and HER2). The decision to offer genetic testing to a breast cancer patient is usually based on her family history, but in the absence of a family history of cancer, some women may qualify for testing based on the age-of-onset and/or the pathologic features of the breast cancer.

Interest in genetic prostate cancer susceptibility testing among african American men.

Six regions for prostate cancer genes have been identified, and it is anticipated that prostate cancer susceptibility testing will be available in the future. This correlational study identified predictors for interest in prostate cancer susceptibility testing among African American men. Participants were 320 African American men from the African American Hereditary Prostate Cancer Study and the South Carolina Prostate Cancer Education and Screening Study participated.
