There are six main causes of nearly all chronic illnesses, including cancer, and they are as follows:
- Genes and genetic programming
- Nutrition
- Toxins/radiation
- Stress
- Lack of physical activity or a physical injury
- Hormone imbalance
One of the most prevalent misconceptions about cancer is that it is usually caused by genetic factors. Jeffrey Bland, in his book, Genetic Nutritioneering, dispels this myth by providing scientific evidence that only 20-30% of chronic disease is attributed to genes. In the case of breast cancer, for example, only 5-10% of cases can be traced to the presence of the BRCA gene; all of the remaining cases are caused by toxins, hormone imbalances, nutritional deficiencies and stress, or a combination of these factors.
