 英国人のティム・ブラウンは、毎朝娘の母乳を飲んでいる。2年前に大腸ガンの診断を受け、娘が結婚する1週間前に入院したが、その1ヶ月後にはガンは肝臓やリンパ節に転移して末期ガンと診断された。手術不能で化学療法を開始した。娘が母乳の効果をテレビで見てアイデアを思いついた。前立腺癌が母乳で軽減したアメリカ人の話を見て、父親に8ヶ月の息子のための母乳一部を与えることを決めた。
 FDAはウェブサイト上で、母乳中の蛋白質が癌細胞を「自滅さ」せることができるとしている。
 母乳は高価で入手には処方箋が必要である。米国には6つの母乳銀行があり、成人向けに特別に提供している銀行が1つある。その他は未熟児向けのものであり、十分に足りていない。

Fighting Cancer With Daughter's Breast Milk?
Expert: 'Promising Research' Could Back Up Man's Claim Breast Milk Helped Cancer Battle

画像When Tim Browne sits down to a bowl of corn flakes in the morning, he slurps up one unusual, and controversial, extra ingredient: his own daughter's breast milk.
A father-and-daughter team battle cancer using breast milk.

He doesn't do it for the taste -- Browne initally said his daughter Georgia's breast millk tasted "not unpleasant, but slightly pungent" -- but for his health.

Nearly two years ago, the retired teacher and musician from Wiltshire, England, was diagnosed with colon cancer. He went into surgery a week before his daughter's wedding, but a month later, doctors told him the cancer had spread to his liver and lymph nodes and was terminal.

Surgery was ruled out this time, so Browne began a course of chemotherapy. Desperate to help, his daughter Georgia came up with the idea while watching a show about breast milk.

"[It was] a man in America. It was prostate cancer this man had and he'd been drinking breast milk every day," she said. "Anyway, this guy really swore by the breast milk and said that it had reduced his tumors."

Georgia was nursing her 8-month-old son Monty and offered to set aside a few ounces of milk every day for Browne. Browne started calling Monty his "milk brother."

"If I have a lactating daughter, why not take advantage of her? As long as Monty didn't mind," Browne said.

Browne had to stop taking his daughter's milk when nausea from the chemotherapy made the taste intolerable to him. He is not cured of the cancer, but he is convinced that taking the milk was the right thing to do.

"It's very difficult to tell if something is working or not," Browne said. "What we feel comfortable about is the process of doing it has been amazing and has helped all of our family."

ABC News medical contributor Dr. Marie Savard said that even though breast milk is known to have benefits and it's make up can't be reproduced, "there's no research to say those same proteins in human breast milk will benefit this man."

Savard said the placebo effect in this case, though, is very real.

"I think the most tender part of this piece is providing hope," she said. "They both together strengthen their relationship. Does it work? We don't know."

Scientists Cautiously Optimistic About Breast Milk Potential

Browne is not the only cancer fighter turning to what scientists call the "highly alternative" treatment of drinking breast milk.

According to the Food and Drug Administration, there have been "intriguing new developments [which] indicate that breast milk may ... reduce the risk of childhood cancer."

A protein in human milk can cause cancerous cells to "self-destruct," the FDA said on its Web site. That unique characteristic of the protein could potentially help battle cancer in adults, some doctors say.

"There's promising research that would indicate that in the future the solution for not only preventing cancer, but even treating and curing cancer might be in human milk," said Dr. Lori Feldman-Winter at Cooper University Hospital in New Jersey.

But for the relatively few adults seeking the alternative treatment, breast milk is expensive, requires a prescription and is difficult to find, unless they happen to be near one of the six milk banks in the United States that were created specifically to provide breast milk to adults.

"In the past we have had one to two inquiries a month," said Dr. Deborah Tuttle of the Mothers' Milk Bank at Christiana Hospital in Newark, Del.

Other milk banks give their milk to premature infants, where doctors prefer to use breast milk because research shows a greater chance of benefits.

As far as breast milk becoming a common treatment for terminal cancer patients, Savard pointed out that there's not enough milk in the country for premature babies. And because they are known to benefit from breast milk, that's where the focus needs to be, rather than cancer treatments.

But because Browne gets his milk from his daughter -- after her son eats -- "I think there's not harm done in this situation," Savard said.

HHS Blueprint to Boost Breast-Feeding
http://www.fda.gov/fdac/features/2003/303_baby.html

Benefits of Breast-Feeding

Science has proved that breast-fed babies have a healthier start in life. Human milk contains a balance of nutrients that closely matches infant requirements for brain development, growth and a healthy immune system. Human milk also contains immunologic agents and other compounds that act against viruses, bacteria, and parasites. Since an infant's immune system is not fully developed until age 2, human milk provides a distinct advantage over formula.

Because breast milk provides protection against germs that a baby or mother may carry, studies in infant feeding have found lower rates of several chronic childhood diseases, including respiratory infections and ear infections, as well as symptoms such as diarrhea, among children who were breast-fed.

Research also suggests that breast-fed infants gain less weight and tend to be leaner at 1 year of age than formula-fed infants. This early indicator may influence later growth patterns, resulting in fewer overweight and obese children.

But infants aren't the only ones who benefit from breast-feeding. Mothers, too, are the recipients of many positive hormonal and physical effects. Breast-feeding releases a hormone in a woman's body that causes her uterus to return to its normal size and shape more quickly and reduces blood loss after delivery. In addition, according to the Blueprint, studies have shown that breast-feeding for longer periods of time (up to 2 years) and among younger mothers may reduce the risk of premenopausal and possibly postmenopausal breast cancer. Also, the risk of ovarian cancer may be lower among women who have breast-fed their children.

Haynes says intriguing new developments indicate that breast milk may even have another role in the battle against cancer. In particular, breast-feeding may reduce the risk of childhood cancer.

Researchers have identified a protein in human milk--human alpha-lactalbumin made lethal to tumors (HAMLET)--that induces apoptosis, or programmed cell death, in which cells, responding to environmental signals, self-destruct. Apoptosis, a relatively new study in biology, is the natural mechanism the body uses to recycle material that is not needed for functioning. When apoptosis is initiated, the cell's genetic material becomes shredded so that the cell cannot replicate itself. With cancer cells, apoptosis is inhibited, allowing rapid growth of dysfunctional cells. Haynes says that the isolation of HAMLET as a trigger for apoptosis in cancer cells could give further weight to evidence linking breast milk to reduced incidences of some cancers.

From a budget standpoint, breast-feeding can save a family hundreds of dollars a year, even with the added cost of breast pumps, devices regulated by the Food and Drug Administration that allow mothers to express milk when they are away from their babies or when they want to save extra milk to be given to the baby at other times. According to the Blueprint, breast-feeding also saves money for insurers and employers by cutting down on doctor visits and sick days.
