This study is published in the January issue of the International Journal of Health Services, a peer-reviewed, leading international public health journal. IGF-1 is a powerful stimulator and regulator of cell-growth and division in humans and cows. The study concludes that increased IGF-1 levels are risk factors for breast and colon cancer. Given the cancer risks, and other health concerns, why is rBGH milk still on the market? Since , independent scientists have expressed concern about the lack of research on the potential health effects of IGF-1 in rBGH milk.

Milk and the Cancer Connection
Dairy products including cow's milk may be associated with an increased risk for breast cancer, according to a new study funded by the National Cancer Institute. Researchers looked at the dietary intakes of 1, women diagnosed with breast cancer and found that those who consumed the most American, cheddar, and cream cheeses had a 53 percent increased risk for breast cancer. Those with ER- breast cancer a designation of estrogen receptor status who drank the most fluid milk had a 58 percent increased risk for breast cancer. Components in dairy such as insulin-like growth factor IGF-1 and other growth hormones may be among the reasons for the increased risk for cancer.

Usual consumption of specific dairy foods is associated with breast cancer in the Roswell Park Cancer Institute Databank and BioRepository.
The dish on dairy
Recombinant bovine growth hormone rBGH is a synthetic man-made hormone that is marketed to dairy farmers to increase milk production in cows. This document summarizes what is known about the product and its potential effects on health. The human form of growth hormone, also called somatotropin , is made by the pituitary gland. It promotes growth and cell replication.
The researchers tracked men in the Physicians' Health Study, an ongoing cohort study, for 11 years. Of the 20, men in the study, 1, developed prostate cancer. At the beginning of the study, investigators used brief dietary questionnaires to estimate the men's consumption of five dairy products, including milk, cheese and ice cream. They found a moderate elevation in risk of prostate cancer associated with higher intakes of dairy products and dairy calcium, adjusting for other risk factors such as age, smoking, exercise levels, and body mass index. The researchers also found that men who drank more than six glasses of milk per week had lower levels of the potentially protective form of vitamin D than men who drank fewer than two glasses of milk per week.
