Improved antioxidant status by omega-3 fatty acid supplementation in breast cancer patients undergoing chemotherapy: a case series.

Introduction Breast cancer is the second leading cause of cancer death in women worldwide and the third most common cancer in India. Various studies have reported that chemotherapy reduces the antioxidant status in patients with cancer. A diet rich in omega-3 fatty acids has been shown to offer protection against breast cancer through various mechanisms. However, there are no reports suggesting a relationship between consumption of omega-3 fatty acids during chemotherapy and antioxidant status in patients with breast cancer. Thus, the objective of this study was to evaluate whether fish oil supplementation could improve the antioxidant status of five women with breast cancer undergoing chemotherapy.
