Summary
Among women with breast cancer (BC), greater BC knowledge has been associated with greater participation in treatment decision-making, patient satisfaction, and survival. Authors identify modifiable determinants associated with BC knowledge. The study findings suggested significant associations of patient self-efficacy and physician emotional support with BC knowledge; physician emotional support appeared to be more important than physician informational support. Further research will be needed to investigate whether interventions that target these two domains may be effective in increasing BC knowledge in disadvantaged populations.
