New study provides BRCA mutation carriers guidance for when surgery has greatest impact

News Release, July 19, 2017

CATONSVILLE, MD, July 19, 2017 – Of the women who carry the mutated BRCA1/2 genes, 45-65 percent will develop breast cancer, and 15-39 percent will develop ovarian cancer in their lifetimes. Many women, especially those who have experienced the death of family members to these cancers, elect to undergo preventive surgeries that can significantly increase life expectancy, but require extensive recovery time and can impact later fertility and quality-of-life. However, few guidelines exist that shed light on the optimal age to undergo these procedures, and in what sequence. A new study in the INFORMS journal Decision Analysis provides insight to help enable physicians and patients make better-informed choices.

According to new research in the INFORMS journal Organization Science, women are more likely to clash with other women at work than they are with male colleagues. While women and men were equally likely to have a 'difficult' relationship with a colleague, women were more likely to cite a female co-worker as the problem.
