Overview
This trial studies the acceptability and how well decision making tool works in supporting decision making in contralateral prophylactic mastectomy in patients with newly diagnosed breast cancer. Decision making tool may help patients with early stage breast cancer make decisions regarding their surgical options.
Description
PRIMARY OBJECTIVES:
I. An online decision support tool will be field tested that provides patients facing a decision about contralateral prophylactic breast cancer (CPM) with evidence-based information about the expected incidence of contralateral breast cancer and the life expectancy benefit of CPM. The tool will be designed for use in clinical settings and viewed jointly by the patient and physician as part of a shared decision making process around CPM.
- OUTLINE
