Newly detected, early stage breast cancer patients in the treatment group will be provided an electronic copy of the DA for their reference via email.

Newly diagnosed, early stage breast cancer patients in the control group will be provided an electronic copy of an alternative educational pamphlet discussing surgical options for breast cancer.

Tools designed to foster shared decision-making by contextualizing the risks and benefits of treatment options around the patient's personal values, thereby allowing them to weigh personal preferences when making treatment decisions. The study team has developed a prototype DA incorporating longitudinal institutional QoL data among patients who have undergone breast cancer surgery .

Monitor the recruitment process of eligible patients. Including tracking how many patients are approached, how many participate and how effective the decision aid engages patient in the decision making process. High participation and engagement indicates a successful implementation. Compare clinician reported length of encounter between interventions as a balancing measure.

Use the validated and accepted Ottawa Decision Aid metrics to assess decision quality, decisional conflict, acceptability, and regret. Conduct semi-structured interviews to gather additional qualitative data regarding the patient experience, and use feedback to modify and improve the content and design of the Decision Aid.

Optimal timing and mode of delivery will be determined by the engagement of patients with the decision aid (DA) based on the time the DA was offered. Qualitative feedback from semi-structured interviews will provide additional context for engagement with paper versus digital copies, and engagement prior to versus after meeting with the surgeon.
