Breast cancer has one of the highest rates in the world. This disease, perhaps more than any other, causes panic and fear in women. Especially if the family already has or had someone with oncology. The renowned scientist Colin Campbell, based on the results of 40 years of research practice in biomedical research, proved that it is not about genetics.

Four risk factors

There are at least four important risk factors for breast cancer that are affected by nutrition. Many of these relationships have been confirmed by the China Study and have been irrefutably substantiated in other studies.

High estrogen levels

Scientifically proven that women who are rich in animal foods and poor in whole plant foods reach puberty earlier and later menopause, thus extending their reproductive period. In addition, throughout their lives, they have higher levels of female hormones – estrogen. There is evidence that estrogen levels are a key determinant of breast cancer risk. Estrogen is directly involved in the cancer process and usually serves as an indicator of the level of other female hormones related to risk factors for breast cancer.

Why is it important to monitor your diet?

The rise in estrogen and related hormones is the result of a typical Western diet rich in fats and animal proteins and poor in dietary fiber.

This means that the occurrence of breast cancer can be prevented by eating foods that will help keep estrogen levels in the blood under control. The sad truth is that most women are unaware of this.


It is not necessary to completely abandon food of animal origin, you can at least reduce its use – source.

Is genetics important?

Repetitive occurrence of the disease in relatives suggests that genes do play a role in the development of breast cancer. In fact, the vast majority of cases of the disease are not related to genetics and hereditary factors.

Among the genes that increase the risk of breast cancer, BRCA-1 and BRCA-2 have received the most attention since they were discovered in 1994. These genes, if mutated, increase the risk of breast and ovarian cancer. Mutated genes can be passed down from generation to generation, they are inherited. But, firstly, only 1 out of 500 people are carriers of mutated forms of these genes. Second, these genes are not the only ones responsible for the development of cancer. And thirdly, the presence of genes or any other gene responsible for the development of breast cancer does not in itself guarantee the occurrence of this disease. Environmental and nutritional factors play a major role in the activation of these genes.

Non-nutritional prophylaxis

Given all the new information about genetic risks and heredity, women are often encouraged to be screened for breast cancer. This is a smart move, especially for those who test positive for the BRCA genes. But it’s important to remember that mammography or genetic tests that detect the presence of BRCA genes do not prevent breast cancer.

Screening is simply observation to detect the progression of the disease to a detectable level. Regular examinations help detect swelling at an earlier stage, which increases the patient’s chances.

Alternative prevention options are now taking medications that actually reduce the activity of estrogen, which is known to lead to a decrease in the risk of developing breast cancer.

“My question is simple: why don’t we first think about what explains such high estrogen levels, and when we recognize that the reason lies in the diet, why not eliminate it? We have enough information today to show that a diet low in animal protein, fat, and high in whole grains can help reduce estrogen levels. Instead of solving the problem by changing the diet, we are spending hundreds of millions of dollars developing and distributing a drug that will not necessarily have the desired effect and will almost certainly have unintended side effects, ”says Colin Campbell.

Dr. Campbell’s recommendation

The author of The China Study recommends a diet free of animal products, refined carbohydrates and fatty ingredients, avoiding alcohol, and exercising frequently. And regular check-ups, especially for those at high risk.

Colin Campbell is convinced that the main source of our health is nutrition. For centuries we have been looking for a pill for all diseases, while it is right in front of our eyes – on a plate. It’s better than anything modern medicine has to offer to fight cancer, multiple sclerosis, second-degree diabetes, heart disease, and other autoimmune diseases.
