Along with better-known risk factors such as family history having dense breasts is one of the strongest breast cancer risk factors. Extremely dense breast tissue affects about 10% of women, with an additional third having heterogeneously dense breasts. Women in these categories have 3-6 times the risk of breast cancer as compared to women with least density. Although breast density is measured on routine screening mammograms, it is not typically communicated to patients. This is changing as a result of legal mandates and approaches need to be tested to effectively integrate this clinical information in care. Therefore,we have developed an intervention to support decision making about cancer risk management (MRI and chemoprevention) for women at clinically elevated risk using a web-based intervention that will evaluate the efficacy of a web based intervention with personalized risk information communication versus usual care.
