Breast Cancer

The following ten references provide converging lines of evidence that focus upon one central point.There are hundreds of millions of different proteins in nature, and only one hormone that is identical between any two species. That powerful growth hormone is insulin-like growth factor, or IGF-I. IGF-I survives digestion and has been identified as the KEY FACTOR in breast cancer’s growth.

IGF-I is identical in human and cow.

If you believe that breast feeding “works” to protect lactoferrins and immunoglobulins from digestion (and benefit the nursing infant), you must also recognize that milk is a hormonal delivery system. By drinking cow’s milk, one delivers IGF-I in a bioactive form to the body’s cells. When IGF-I from cow’s milk alights upon an existing cancer…
