A qualitative study identifying challenges resulting from complex evidence on lifestyle factors and cancer: perspectives from Black and Latina cancer survivors and healthcare providers.

Purpose: Most breast cancer survivors have challenges with adopting healthy lifestyle behaviors. This may be due to contextual challenges that result from the complex nature of the evidence. To address this gap, we explored the experiences of breast cancer survivors of color and oncology healthcare providers.
Methods: Content analysis with inductive and deductive approaches was used for semi-structured interviews with 26 female breast cancer survivors and 10 oncology healthcare providers from Greater New Haven, Connecticut.
Results: Survivors identified substantial confusion on the evidence regarding lifestyle behaviors and breast cancer, stemming from inadequate healthcare provider counseling and an overreliance on informal sources of information. Providers identified lack of evidence-based knowledge as a barrier to counseling on these topics. There was a mixed perspective regarding the consistency of evidence, stemming from a combination of gaps in the available evidence and accessing evidence-based knowledge from a wide range of professional resources. Some providers perceived the guidelines as consistent; others felt guidelines were constantly changing, impacting how and on what they counseled. Therefore, many healthcare providers in oncology care relied on generic messaging on lifestyle behaviors after a cancer diagnosis.
Conclusions: Inconsistent information sources, the rapidly changing evidence, and gaps in the current evidence contribute to generic messaging about lifestyle behaviors and may inhibit a survivor's ability to engage in behavior change. Consistent and uniform healthy lifestyle guidelines for cancer outcomes may address both provider and patient level barriers to knowledge.
