Level one evidence reported poorer outcomes among patients taking dietary supplements after breast cancer (BC) diagnosis. We evaluated dietary supplement behaviours among adult BC patients via questionnaire. Sociodemographic data, supplement use, attitudes, and healthcare provider (HCP) advice were analysed. Of 185 participants, 45% were regular supplement users following diagnosis. Regular supplement use was associated with higher education level (p = 0.05). The majority perceived supplements to be safe. Over half reported not receiving advice from HCPs. In summary, supplement use is prevalent among BC patients. Development of guidelines in relation to safe use of dietary supplements after cancer diagnosis is crucial.
