Abstract

Cancer is a leading cause of death globally, with lifestyle factors, including diet, significantly influencing cancer risk and patient outcomes. This article explores the critical role of diet in both the prevention and treatment of cancer. Evidence suggests that a diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats can reduce the risk of various cancers. Key nutrients and compounds such as antioxidants, phytochemicals, fiber, and omega-3 fatty acids exhibit protective effects against cellular damage and inflammation, contributing to cancer prevention. During cancer treatment, a balanced and nutrient-dense diet supports patients by maintaining strength and energy, managing side effects, bolstering immune function, and promoting healing. This comprehensive overview underscores the importance of dietary choices in mitigating cancer risk and enhancing treatment efficacy, advocating for nutrition as a pivotal element in the broader strategy against cancer.
