Drinking red wine in moderation may reduce one of the risk factors for breast cancer, providing a natural weapon to combat a major cause of death among U.S. women, new research from Cedars-Sinai Medical Center shows. The study, published online in the Journal of Women's Health, challenges the widely-held belief that all types of alcohol consumption heighten the risk of developing breast cancer. Doctors long have determined1 that alcohol increases the body's estrogen(雌性激素) levels, fostering the growth of cancer cells.

But the Cedars-Sinai study found that chemicals in the skins and seeds of red grapes slightly lowered estrogen levels while elevating testosterone(睾丸素) among premenopausal(绝经前期的) women who drank eight ounces of red wine nightly for about a month.

White wine lacked the same effect.

Researchers called their findings encouraging, saying women who occasionally drink alcohol might want to reassess their choices.

"If you were to have a glass of wine with dinner, you may want to consider a glass of red," said Chrisandra Shufelt, MD, assistant director of the Women's Heart Center at the Cedars-Sinai Heart Institute and one of the study's co-authors. "Switching may shift your risk."

Shufelt noted2 that breast cancer is the leading type of women's cancer in the U.S., accounting3 for more than 230,000 new cases last year, or 30 percent of all female cancer diagnoses. An estimated 39,000 women died from the disease in 2011, according to the American Cancer Society.

In the Cedars-Sinai study, 36 women were randomized to drink either Cabernet Sauvignon or Chardonnay daily for almost a month, then switched to the other type of wine. Blood was collected twice each month to measure hormone4 levels.

Researchers sought to determine whether red wine mimics5 the effects of aromatase(芳香酶) inhibitors, which play a key role in managing estrogen levels. Aromatase inhibitors are currently used to treat breast cancer.

Investigators6 said the change in hormone patterns suggested that red wine may stem the growth of cancer cells, as has been shown in test tube studies.

Co-author Glenn D. Braunstein, MD, said the results do not mean that white wine increases the risk of breast cancer but that grapes used in those varieties may lack the same protective elements found in reds.
