New Breast Cancer Concern
by Robert Cohen

There is a type of breast cancer that was once considered to be extremely rare; invasive lobular carcinoma. A new study, published in the current issue of the Journal of the American Medical Association (JAMA 2003; 289:1421-4), reveals that rates of this breast cancer jumped from 9.5% of all breast cancers to 15.6% in just a 12-year period (from 1987 to 1999). This study was based upon the analyses of 190,000 cases of breast cancer.

While most breast cancers are first detected as "lumps" through self examination, this cancer is quite different. Invasive lobular carcinoma begins inside of mammary ducts. A related commentary in the current issue of the British Medical Journal reveals: "In the classic form of this cancer, the tumor cells are arranged in single file or strands infiltrating the breast stroma. So, unlike the more common type of breast cancer that develops as lumps, this type grows as sheets of cancerous cells, making it more difficult to detect by physical examinations and mammography."

For every breast cancer scientist, there seems to be a different theory. But there is one thing with which all researchers agree: Breast cancer is about hormones. Something triggers a series of yet-to-be understood hormonal events.

Something happened to cause this dangerously lethal trend. Why such an increase? What event is affecting women differently in 1999 that was not affecting them in 1987? For one thing, women have been eating increased levels of concentrated dairy products thanks to the ever increasing effective ad campaigns run by the dairy industry's marketing firms. Each bite of cheese and serving of yogurt contains steroid hormones. In his landmark book, Don't Drink Your Milk, Frank Oski, M.D. (once the director of Pediatrics at Johns Hopkins Hospital) wrote: "About 80 percent of cows that are giving milk are pregnant and are throwing off hormones continuously. Progesterone breaks down into androgens..."

Pregnant cows also produce hormones which instruct their own mammary tissues to grow. It should be no surprise that progesterone, prolactin, oxytocin, and estrogen affect humans who ingest bovine steroid hormones. In 1970, the average American consumed just ten pounds of cheese. By 1999, the average American was consuming 30 pounds of cheese. Ten pounds of milk are required to produce one pound of cheese. Could this be the missing link to understanding the dramatic increase in the rate of invasive lobular carcinoma?

Post-menopausal women are not supposed to be producing milk. Hormonal messages to do so are contrary to a woman's physiology. The inappropriate presence of lactation hormones may very well explain the emerging invasive lobular carcinoma explosion among the ever increasing population of baby boomers who are becoming post-menopausal.

Although Monsanto's genetically engineered bovine growth hormone was not approved until 1994, millions of pounds of milk from test herds entered America's milk supply as early as 1989 in New York, Miami, and Pennsylvania. Genetically engineered milk contains increased amounts of insulin-like growth factor, the hormone identified as a key factor in the growth of every type of breast cancer.

An increase in the consumption of concentrated hormone-rich dairy products coupled with America's first "Frankenfood" (genetically engineered milk) may lead to the conclusion that "Got milk?" is responsible for "Got Cancer."
