Can the IGF-1 in Colostrum Cause or Further Cancer?
Recent developments have prompted an intensive search for information regarding colostrum involvement in the plight of cancer. This issue has evolved in part from the evidence derived from medical research studies indicating that IGF-1, insulin-like growth factor-1, plays a role in the progression of carcinoma or sarcoma. It is the position of Symbiotics, Inc., the producer of New Life Colostrum, that colostrum does not play a causal role in the onset of this disease, nor does it mediate the proliferation of cancerous cells. The role of IGF-1 in the proliferation of cancer cells is not exactly clear. Insulin-like growth factor 1 is a peptide hormone secreted by the liver in response to growth hormone. Mammals produce IGF-I for normal cellular activities. IGF-1 regulates cellular activities such as cell proliferation, differentiation and apoptosis. A feature of cancer is uncontrollable proliferation, loss of differentiation and an inability to undergo apoptosis. Because IGF-1 is a stron
