ReviewUse of antioxidant supplements during breast cancer treatment: a comprehensive review.
An estimated 45-80% of breast cancer patients use antioxidant supplements after diagnosis, and use of antioxidant supplements during breast cancer treatment is common. Dietary supplements with antioxidant effects include vitamins, minerals, phytonutrients, and other natural products. We conducted a comprehensive review of literature on the associations between antioxidant supplement use during breast cancer treatment and patient outcomes. ⋯ The evidence is currently insufficient to inform clinician and patient guidelines on the use of antioxidant supplements during breast cancer treatment. Thus, well designed clinical trials and observational studies are needed to determine the short- and long-term effects of such agents.
