The natural history of ductal carcinoma in situ (DCIS) is largely unknown, and its optimal treatment remains controversial. Using semi-structured interviews, this study compared 18 White and 16 Latina women's understanding of their DCIS diagnosis, treatment decision-making processes, and satisfaction with care. Ethnic differences were observed in cognitive and emotional responses to DCIS, with White women generally reporting a better understanding of their diagnosis and treatment, and Latinas reporting more distress. Regardless of ethnicity, women with DCIS preferred that physicians discuss treatment options and attend to their informational and emotional needs. Satisfaction was associated with adequate information, expediency of care, and physicians' sensitivity to patients' emotional needs.
