Best foods that help your body fight cancer

Dr. Dawn Mussallem, a double board-certified physician and stage 4 breast cancer survivor, has shared five powerful foods that she believes played a crucial role in her recovery and can help others support their health naturally. Speaking on a recent podcast, Dr. Mussallem emphasized that while no food can guarantee cancer prevention or cure, certain nutrient-rich options can strengthen the body’s defences and aid healing alongside medical treatment.

One of the top foods on her list is berries—such as blueberries, strawberries, and raspberries—known for their high antioxidant content. Research, she noted, shows that consuming berries at least twice a week can lower the risk of developing breast cancer and, for survivors, reduce mortality risk by up to 25%.

Next are cruciferous vegetables like broccoli, cauliflower, kale, and Brussels sprouts. These vegetables contain the enzyme myrosinase, which helps activate compounds that support hormone balance by converting estrogen into a less active form. Regular intake of these vegetables has been linked to reduced cancer growth and improved overall health.

Dr. Mussallem also highlighted the benefits of soy foods, including tofu and soy milk. Studies suggest that moderate soy consumption may support better outcomes among breast cancer survivors due to the presence of plant-based estrogen-like compounds that can help regulate hormonal activity.

She further encouraged incorporating colorful vegetables and legumes, rich in phytonutrients and fibre, to boost antioxidant activity, improve digestion, and reduce inflammation—key factors in maintaining long-term wellness.

Importantly, Dr. Mussallem clarified that her approach focuses on whole, plant-based foods rather than supplements or extreme diets. While food cannot replace treatment, she said, it can play a powerful complementary role in recovery and prevention. Her insights reflect a growing body of research connecting dietary patterns with cancer resilience and overall wellbeing.
