Summary

This study tests whether a decision aid and training for surgeons can help women aged 70 and older with low-risk stage I breast cancer make better treatment choices. About 402 participants will be split into two groups: one where surgeons get shared decision-making training and patients receive a decision aid before their first visit, and another with usual care. The goal is to see if the intervention reduces aggressive treatments like mastectomy or radiation, while improving how informed patients feel about their options.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: shared decision-making training and decision aid
What this could lead to: If successful, this could help older women with low-risk breast cancer make more informed, less aggressive treatment choices, improving quality of life.
What could go wrong: This is a behavioral study, not a drug trial, so it won't directly treat cancer. Results depend on how well surgeons and patients adopt the tools, and may not apply to all settings.
