Abstract
BACKGROUND: As BRCA1/2 testing becomes more routine, questions remain about long-term satisfaction and quality of life following testing. Previously, we described long term distress and risk management outcomes among women with BRCA1/2 mutations. This study addresses positive psychological outcomes in BRCA1/2 carriers, describing decision satisfaction and quality of life in the years following testing.Entities:
