Part of preventing an occurrence or re-occurrence is knowing what happened in the first place. An extensive history as well as testing to understand one’s individual biochemistry is critically important, especially in the complexity of breast cancer. A combination of assessing nutrient status, looking at genetics, addressing free radicals and establishing a healthy micro-biome are all important parts of building an immune system that can stand up to cancer. Breast cancer, while frightening, is not insurmountable. By taking a whole person approach, we can have an optimal outcome. Breast cancer does not have one cause but many. Breast cancer is not one gene, but epigenetic. The more we explore a complete network of pathways the stronger ability we have to understand each person, their journey towards health, and their ability to prevent and overcome breast cancer.
