What this trial studies

This trial evaluates the effectiveness of an online decision support tool designed to assist patients with newly diagnosed breast cancer in making informed choices about contralateral prophylactic mastectomy (CPM). The tool provides evidence-based information regarding the risk of contralateral breast cancer and the potential life expectancy benefits of undergoing CPM. Patients will use this tool during consultations with their breast cancer surgeon and will complete questionnaires before and after the consultation to assess its impact on their decision-making process.

Why it matters

Potential benefit: If successful, this tool could empower patients to make more informed decisions regarding their surgical options, potentially improving their satisfaction and outcomes.

How similar studies have gone: Other studies have shown that decision support tools can significantly improve patient decision-making in cancer care, suggesting a positive outlook for this approach.
