Is this trial a fit for you?
✓Likely a good fit
Women aged 18 or older with average/high lifetime breast cancer risk or early-onset breast cancer, able to speak English or Spanish, and willing to participate and allow medical record review.
✕Probably not a fit
Some participants may not experience direct personal benefit from the environmental exposure assessments.

What this trial studies
This observational study explores attitudes toward environmental exposure risk assessments (EERA) and return of results among female breast cancer patients and their providers. It has three aims: (I) gauge patient interest and emotional responses through surveys and interviews, plus medical record review; (II) assess COH providers' views on integrating EERA into workflows; (III) have patients complete baseline and follow-up surveys, wear a wristband for one week, and undergo occasional interviews with medical record review. Participants are adults 18+ who are English- or Spanish-speaking, with average/high risk or early-onset breast cancer, and who consent to participate. The study is non-interventional and observational in nature.
Why it matters
Potential benefit: If successful, findings could guide how to effectively integrate environmental exposure information into breast cancer care and patient communication.
How similar studies have gone: Prior research in related areas has shown that stakeholder attitudes toward exposure data can influence implementation, but this exact approach is novel in this setting.
