Dietary principles for patients with pregnancy-associated breast cancer

The nutritional management of pregnant women with breast cancer is crucial to ensure the health of both the mother and the fetus. The interplay between cancer progression, pregnancy, and diet poses unique challenges that require a comprehensive approach to treatment. Objective: To review the international scientific perspectives on the dietary principles best suited for managing pregnant women with breast cancer, focusing on balancing maternal and fetal health, minimizing side effects of cancer treatments, and maintaining optimal nutritional status. Methods: An extensive review of current international scientific literature was conducted to identify key dietary components, nutritional interventions, and guidelines that influence outcomes for pregnant breast cancer patients. Results: An optimal diet is characterized by adequate energy intake, high-quality proteins, omega-3 fatty acids, micronutrients, and antioxidant-rich foods, while avoiding carcinogenic, pro-inflammatory, and hormonally active foods. Conclusion: Nutritional therapy for pregnant women with breast cancer requires an individualized, evidence-based approach, aimed at optimizing maternal and fetal health, supporting cancer therapy, and enhancing prognosis. Further research is needed to establish standardized dietary protocols.
