Breast, Colon and Prostate

IGF-1

Insulin-like growth factor 1 is a hormone that promotes cell development and growth - also development and growth of cancer cells.
Obesity, dairy and meat consumption stimulate production of IGF-1.

Breast Cancer

The discovery of the "breast cancer gene"—BRCA-1—in 1994 led many women to believe that breast cancer was hereditary—just bad luck. In some cases, it led to premature amputation (!). The most famous example is that of actress Angelina Jolie. Breasts removed.

Is that true? Just bad luck?

No. Only 3% of all breast cancers can be attributed to genetic predisposition. And even then, environmental factors determine whether the inherited gene will develop into cancer. But for various economic reasons, it's more advantageous to scare people, offer surgery, and prescribe medication.

The biggest risk factors for breast cancer are:

Early menstruation
Late menopause
High blood levels of female hormones
High blood cholesterol

A diet high in animal products and processed carbohydrates:

Promotes early menstruation
Increases the age of menopause
Increases blood levels of female hormones
Increases cholesterol levels

You can do the math right?

Estrogen exposure is almost three times higher in women who eat a lot of animal products, and it's the estrogen level that has a significant impact on the development of breast cancer. Because a dairy cow typically produces milk 300 days a year (completely against its nature), the estrogen dose is ridiculously high, and therefore also for the consumers of her breast milk: dairy consumers!

Colon Cancer

Colon cancer (colon/rectum = colorectal cancer) is much more common in "developed" countries than in less developed ones. This, again, has nothing to do with genetic predisposition, but rather with lifestyle, where diet plays the most significant role.

In the Western world, where a standard diet rich in animal products prevails, half the population will have developed a tumor in the colon by the age of 70, with 10% developing into a malignant tumor.

The single greatest risk factor for developing colon cancer is meat consumption. This undeniable evidence has been available for a long time. Furthermore, research has shown that a lack of fiber in the daily diet promotes colorectal cancer, while eating enough fiber reduces the risk of this cancer by 33%!

Prostate Cancer

Prostate cancer is a very slow-developing cancer, and a man with prostate cancer is likely to die sooner from causes other than this cancer, but not always. Prostate cancer is most common in countries that follow a Western diet and lifestyle. Here too, dairy is the devil. Studies show that consuming more dairy doubles your risk of prostate cancer and quadruples the risk of a fatal form of prostate cancer, compared to men who consume little or no dairy.
