• The decision board explains the risks and benefits of mastectomy, excision and radiation, excision, radiation, and tamoxifen, excision alone, and excision without radiation and tamoxifen for women with DCIS.
• Patients will receive a decision board to take home for review. Two fifteen-minute telephone interviews will be conducted, one approximately one week after enrollment and one 2 months after enrollment.
• In the phone interviews, patients will asked to complete a brief survey. This survey will ask abou DCIS in general, the patient's treatment decisions, their feelings, as well as their experience with the decision board.
