Mediterranean diet and breast cancer: A narrative review

Breast cancer is the second most common neoplasm and the deadliest among women worldwide. Its incidence varies according to human development and is associated with several risk factors, including age, genetic factors, obesity, and dietary habits. Recent research has revealed a significant influence of dietary habits on the onset and progression of this disease, which is why this review aims to comprehensively analyze the available literature to understand better the role played by the mediterranean diet in the development and management of breast cancer. The mediterranean diet has anti-inflammatory and antioxidant effects, may influence gene regulation, and produce hormonal and intestinal microbiota changes, resulting in improved quality of life for breast cancer patients by alleviating symptoms such as pain, inflammation, and reducing the risk and mortality from this disease. Evidence suggests that greater adherence to the mediterranean diet reduces the risk of breast cancer, as well as an improvement in patients' quality of life and mortality. These findings underscore its potential relevance in the context of dietary patterns associated with breast cancer prevention and management, which could inform considerations for public health policies. Further research is needed to confirm these observations and to understand the underlying mechanisms better.
